What is Water-as-a-Service?

Start with the model, because the whole story lives there. Henry is blunt about it: “the technology is not the problem,” he told me, “the delivery model, the business model is the solution to our biggest infrastructure problems.”

In the normal world, a town buys a plant. It borrows the money, hires a firm to design and build it, and then owns and runs it more or less forever. Water-as-a-Service flips every one of those verbs onto the provider. Seven Seas finds the capital, builds the plant, owns it for good, operates it, and you simply buy the treated water, usually a fixed charge that pays down the plant plus a price per cubic meter you actually use. You are not buying a machine, you are buying water, the way you buy electricity. Seven Seas liked the idea enough to trademark the name, WaaS, which tells you they think the model, not the membrane, is the product.

Where it sits: the water delivery-model zoo

“A private company runs a water plant” hides at least six different deals, and the line that separates them is simple: who puts capital at risk, and who ends up owning the thing. At one end is Design-Bid-Build, where the city pays for everything and owns it forever. In between sit the half-measures: Design-Build-Operate, where the city still finances and owns the plant but hires one team to build and run it; and Build-Operate-Transfer, where a private builder fronts the cash, runs the plant for twenty or thirty years, then hands the keys back. Water-as-a-Service is the far end, where the provider pays, owns, and the keys never change hands at all. You just keep buying the water.

If that picture feels abstract, the table below puts the who-pays, who-owns and who-runs of each model side by side.

The real innovation is the deal, not the desalination

Here is the part I find genuinely clever, and it has nothing to do with membranes. The desalination itself is decades-old, widely available technology. The breakthrough is the deal. As Henry tells it, water has always had two camps that refuse to talk to each other: the engineering builders, who can size a pump but freeze when you ask them for an IRR (the internal rate of return, the yardstick for what a project earns), and the project-finance money, which can write the check but often cannot spell reverse osmosis. Water-as-a-Service forces those two into one company that gets paid only when the water flows, which kills the margin each camp would otherwise stack on the other.

And the model compounds. Henry’s real moat is not a plant, it is having done this so often that he no longer needs a fresh financial close, new engineers, or “a new lawyer that tells us how the water-as-a-service agreements work” for every deal. Do it once and it is hard. Do it 200 times and it is a machine.

Why doesn’t the US just do this everywhere?

If the model is this good, why hasn’t every thirsty American city switched? Because of a wall called Design-Bid-Build, built from two materials. The first is law: almost every US state requires public construction to go to the “lowest responsible bidder,” which needs a finished design to bid against, which legally splits design from construction. That split, mandated by statute, is the US municipal default.

The second material is decisive: cheap money. A city borrows through tax-exempt municipal bonds that run roughly 150 to 210 basis points below what a private company pays, topped up by the federal State Revolving Funds (about $133 billion in loans over 25 years) and WIFIA. So a US utility’s own credit is cheaper than any private owner’s, and it rarely needs a private balance sheet at all. Add that about 80% of Americans get their water from a government-owned system, plus a long memory of privatizations that soured (Atlanta handed its water to a private operator in 1998 and took it back by 2003), and you have ground Water-as-a-Service simply cannot occupy.

So where does Water-as-a-Service actually win?

It wins where that wall is thin, and there are three such places. The first is industrial customers: a factory, a mine, or a refinery signs the water contract directly, with no public tender, moving a water plant off its balance sheet so its capital stays in its core business. Henry says these are still “a handful” of his book, but they are the growth leg, and the cleanest pure-play around, Belgium’s listed Ekopak, is built entirely on industrial reuse.

The second is islands and decentralized systems, Seven Seas’ heartland: across the Caribbean and Latin America, where public capital is thin and the cheap-muni market does not exist, a private build-own-operate provider is simply the practical route. Seven Seas is the primary water supplier to the US Virgin Islands, St. Maarten and the British Virgin Islands. The third is anywhere a small, fast, brackish or reuse plant beats a megaproject. Set California’s Carlsbad plant (conceived 1993, opened 2015, around $1 billion) against Henry’s decentralized model, where his crews commission a working island plant in under two months.

The catch: it follows the money, not the thirst

Before you remortgage the house to buy water annuities, here is the catch the brochures skip. A 30-year water contract is only ever as good as the customer signing it. Henry uses a mortgage analogy: “the better your credit rating, the lower your mortgage rate,” and a water deal is no different, because “we need to make sure that we get paid.” So the model needs strong, creditworthy off-takers, which in practice means the US and other wealthy economies, and it struggles exactly where water is scarcest and poorest. The development-finance literature says the same thing in colder language: capital flows to creditworthy buyers, not to need. Water-as-a-Service is a credit instrument first and a water technology second.

There is one tidy exception that proves the rule. The largest market on earth for long-term water-purchase contracts is the Gulf, among the most water-scarce regions there is, but also high-income and state-backed. Scarcity did not unlock it. A guaranteed check did.

Why is a Water-as-a-Service company worth a billion dollars?

Now the part a fund actually pays for. Strip away the water and a book of these contracts is recurring, contracted revenue, locked in for decades, from customers obliged to pay. That is an annuity, and it behaves like a toll road: the predictable, inflation-resistant cash flow infrastructure investors are built to buy. The demand behind it is bottomless: the US alone faces a reported $1.26 trillion in water and wastewater needs over 20 years (US EPA, 2023 to 2024).

Now the arithmetic. In March 2020, Morgan Stanley’s infrastructure arm bought Seven Seas for a reported $500 million. In May 2025, the Swedish investment firm EQT agreed to buy it for a reported $1 billion-plus. By my count, in my own Leviathan database, that is the same asset roughly doubling in five years, while never once ringing a stock-market bell.

What changed in between was not the technology. Henry took a “great company” that had gone “stagnant” and rebuilt its strategy, its team, and a sales pipeline “where before there was none.” Four years, he reminds me, is a nanosecond in infrastructure.

So what did the billion-dollar water exit actually look like?

It looked like a company passed between investors its whole life. Private-equity firms owned Seven Seas through the 2000s. In 2016 its parent, AquaVenture, went public on the New York Stock Exchange under the fitting ticker WAAS, raising about $134.6 million (Renaissance Capital, 2016). In 2020, Culligan took AquaVenture private and carved Seven Seas out, selling it to Morgan Stanley Infrastructure Partners for a reported $500 million (BusinessWire, March 2020). Then, in May 2025, EQT agreed to buy it for that reported $1 billion-plus (EQT, 2025). Four owners across two decades, and the strange part: of those four prices, only the 2016 IPO was ever officially confirmed.

And the exit was not luck. It was designed from the day Henry took the job. When he interviewed with Morgan Stanley, he asked the only question that mattered: what is your exit strategy, and is an IPO an option? They told him plainly it was not. So from September 2021, everyone knew exactly what ending they were building toward, which is roughly how you actually buy a water company and turn a profit.

Who is Seven Seas Water, exactly?

Quick context, because, again, you have rightly never heard of them. Seven Seas Water Group has been treating water for about two decades. Today it runs more than 200 desalination and wastewater plants across the US, the Caribbean and Latin America, from islands like the US Virgin Islands all the way to Peru, with headquarters split between Tampa, Florida and Houston, Texas. Its core trick is brackish-water desalination, taking water that is salty but not quite seawater and making it drinkable, plus wastewater treatment through its AUC division. Not a household name, just the quiet plumbing behind a lot of other people’s taps. Which is exactly the kind of unglamorous, mission-critical infrastructure that hides in plain sight until a fund pays a reported billion for it.

Why do these water companies sell to funds instead of going public?

So if the model is this good, why has Seven Seas never simply floated? Henry’s answer is that public markets are “a cyclical animal,” and that water is tiny by stock-market standards, mostly regulated utilities and the firms selling “pumps, pipes, valves.” Private owners can price the contracted future; public markets mostly price last year’s profit. So the annuity keeps trading privately, between infrastructure funds. Morgan Stanley, then EQT, with Ember, KKR and XPV chasing the same playbook, and the price tags to match: KKR paid a reported $2.07 billion for the environmental group Ecorbit in 2024, while a closer cousin, H2O Innovation, went private for C$395 million. This is water privatization in slow motion. I asked the same question of a far bigger name in 600 private water bets and zero public exits, watched another platform turn bolt-ons into a reported $1.8 billion exit, and mapped the patient money behind it in how HG Ventures became a top-5 water investor. I even sorted water’s investors into three tribes once, because I am, as ever, fun at parties. Subscribe to the (don’t) Waste Water newsletter here.

How to invest in water if you’re not a billion-dollar fund

So can you, personally, own a slice of this? Mostly, no, and it is worth being honest about that. The Seven Seas kind of deal lives behind billion-dollar infrastructure funds with institutional minimums, not a brokerage app. What is actually open to you is the unglamorous public half Henry described: listed water utilities, the big equipment makers, and a handful of genuine water-focused funds and ETFs (an ETF being a basket of stocks you buy in a single click). The recurring water-as-a-service upside, the annuity that EQT just paid a reported billion for, stays almost entirely private. Henry, for what it is worth, defines a “water company” generously, counting even firms that simply help others use less of it, so if you go looking, look wider than the obvious utilities.

The frontier Henry keeps pointing at is the “third leg,” industrial Water-as-a-Service, factories handing their entire water headache to an operator and keeping their own capital for their own business. And my crystal ball still says the one chapter Seven Seas keeps skipping, an actual IPO, is the most likely next one, the very thing the whole sector keeps not doing. Whichever way EQT eventually rings that bell, the lesson holds. In water, the billion-dollar moments rarely arrive with a gong on an exchange floor. They happen quietly, between people who understood the delivery model long before anyone else was listening. Go listen to the full conversation with Henry on the podcast, it is genuinely worth your time, and it will change how you read the next water headline.

Frequently asked questions

What is Water-as-a-Service (WaaS)?

A model where a company builds, owns and operates a water or wastewater plant and sells the treated water under a long-term contract, instead of selling the plant itself. The customer pays for water, usually a fixed charge that covers the plant plus a price per cubic meter, with no upfront capital; the operator carries the financing and the risk. Seven Seas Water trademarked the term.

How is Water-as-a-Service different from Build-Operate-Transfer or Design-Build-Operate?

Under Design-Build-Operate, the public customer finances and owns the plant the whole time and just hires one team to design, build and run it. Under Build-Operate-Transfer, a private developer finances and runs it for 20 to 30 years, then hands ownership back. Under Water-as-a-Service, the provider owns the plant for good and you never own it, you only ever buy the water.

Why doesn’t US municipal water use Water-as-a-Service?

Two reasons. Low-bid procurement laws push cities into Design-Bid-Build, where the public owner finances and owns the plant. And tax-exempt municipal bonds plus federal loan funds make public capital cheaper than any private owner’s, so a US city rarely needs a private balance sheet. WaaS therefore concentrates on industrial customers, islands and decentralized systems instead.

Who owns Seven Seas Water?

EQT Infrastructure, through its EQT Infrastructure VI fund, since its 2025 acquisition from Morgan Stanley Infrastructure Partners. Before that it belonged to Morgan Stanley (2020 to 2025), and earlier to AquaVenture Holdings and its public shareholders (NYSE: WAAS), with Culligan owning the parent briefly in 2020.

What did EQT pay for Seven Seas Water?

It was never officially disclosed. Sources put the enterprise value above $1 billion including debt, on a deal agreed on 22 May 2025, roughly double the reported $500 million Morgan Stanley paid for the same business in 2020.

How big is the water-as-a-service market?

There is no single reliable figure: independent estimates put growth at roughly 7 to 13% a year through the early 2030s, but the absolute market-size numbers vary about threefold between firms. The hard number is the demand behind it: the US EPA puts 20-year US water and wastewater needs at about $1.26 trillion.

How do you invest in water?

For most people, through listed water utilities, water-equipment makers, and water-focused funds or ETFs. Direct stakes in private water-as-a-service operators like Seven Seas are generally limited to institutional investors and large infrastructure funds. —

The post Seven Seas Water: How Water-as-a-Service Built a $1B Exit appeared first on (don't) Waste Water.

The water sector is not about to crack. It is standing inside an inflection point it has never actually reached before, and that is exactly why it feels so fragile. By my count, 2025 beat every record that matters: the bench of private-equity-owned water platforms grew from 42 companies in 2015 to nearly 600, private equity ran 165 water acquisitions in a single year, and on day one of the Global Water Summit, the sector’s first and only unicorn, Gradiant, doubled its worth to a $2 billion valuation. Every load-bearing part of a self-sustaining capital machine is finally in place, except the last one. There is no IPO pipeline. And a machine that cannot complete a single lap does not break from too much money pouring in. It breaks from money that cannot get back out. So the real question is not whether water tech is overheating. It is whether anyone can finally cut the cord.

So is the water sector actually about to crack?

Here is the honest answer, and it is the one I went to Madrid to test: no, it is not cracking, but it is closer to the edge than it has ever been. Of the five steps a water company climbs from idea to established business – starting up, raising early rounds, fuelling growth, handing over to private equity, and finally exiting – the first four all beat their records in 2025 and early 2026. Only the fifth, the exit, is missing. That is not a sector overheating. That is a sector that has built every part of a machine except the door the money leaves through.

I think about a water company the way I think about a yo-yo. A founder gives it the first flick of the wrist, and with enough money, brains and muscle it spins faster and faster – that is venture capital, then growth capital. But a yo-yo always has a string attached, and the string eventually calls it back. In my metaphor, that is a private equity fund: it sends the company down on a scaling journey, then reels it in to sell to a bigger fund that flicks it harder still. Only when someone finally turns that yo-yo into a water wheel – a full-scale, self-sustaining company – can the cord be cut. That final player is the riddle. And the riddle is what decides whether the whole thing holds.

So I went to find the players themselves. Over three days in Madrid I got to sit down, one to one, with six of the people who actually move this money – the founders, the funds, and the bankers who broker the exits – plus a dozen more conversations off the record. Almost none of what follows was said from a stage. It is the candid version, the kind you only get sitting across a table, and it is the reason I think the picture is both more exciting and more fragile than the press releases let on.

What does the water capital chain actually look like in 2025?

On the private-equity side, the share of all water deals run by PE buyers basically doubled in a decade, from around 14% in 2015 to 37% last year, with 165 PE-led acquisitions in 2025 alone – the most on record. And the shape is telling: 80 of those 165 were sub-$10 million targets. High velocity, low ticket. The loop is spinning faster than ever, but with smaller cheques. The early stages tell the same story of abundance: by my count there were 108 funding rounds along the early steps in 2025, against 33 in 2018, and the specialist funds writing those checks are now raising faster than the companies they back.

It is not just the venture end filling up. XPV, on the later-stage side, closed two new vehicles in 2025 worth $625 million and pushed past a billion dollars under management. Thematic European money is arriving for the first time too – Summa Equity beefed up a whole water team this year. And the biggest strategic in the world, Xylem, is quietly underwriting the early stage through a fund of funds. So the intake valve is wide open from every direction at once. (I dug into how private equity actually plays water in my newsletter on the three PE strategies reshaping water tech, if you want the mechanics – and you can subscribe here while you are at it.) If you want the founder’s-eye view of where all this capital starts, I walked through it in how water-tech venture capital actually fuels growth.

Why are there 600 private water bets but no way out?

Here is the catch I keep coming back to inside my Leviathan database, where I have logged 5,531 completed water deals since the year 2015. The bench of PE-owned water platforms went from 42 companies in 2015 to nearly 600 in 2025 (arguably, by my own definition – I will expand on that another day). But a platform is not an exit. When private equity sells to private equity, the yo-yo just gets flicked again by a bigger hand. The string is still attached. And each of those platforms now swallows about four times as many bolt-on acquisitions as it did a decade ago, which means the loop does not run on building new platforms anymore – it runs on feeding the ones it already has.

So who does cut the cord? Mostly the strategics, and they are picky in a very specific way. Two of the people who broker these deals for a living sat down with me to walk through it. As Samrat Karnik, who runs water M&A at Houlihan Lokey, put it, a target has to be ready before a strategic will touch it.

That is why the dollars flow to established, profitable, growing platforms and not to technology bets. Veralto bought Aquatic Informatics for its scaled software platform; Badger Meter bought s::can and then SmartCover, both proven businesses with a real commercial engine. As David Rose of Thales Water Advisors framed it, acquiring a company can simply be a faster, de-risked proxy for R&D – but only once it is proven. The growth itself comes in a strict order: a product gap first, then a market gap, then a geography.

Will Gradiant IPO?

Then, sitting across the table from me, Anurag Bajpayee said the quiet part out loud. Gradiant – now a two-time unicorn after its Series E landed at a $2 billion valuation – stopped raising money to survive about four years ago. It is a cash generator now, and the biggest use of proceeds from this round is acquisitions, not runway. So why raise at all, and why talk about going public? Because, he told me, you cannot control your own destiny otherwise.

Notice what he is not saying. There is no date, and the IPO market right now is not exactly throwing a party. What he is saying is that liquidity is already happening privately: Gradiant has a reasonably viable secondary market for its shares, and some of the people who came in at Series A and B have already cashed out at very attractive multiples. That matters, because it is the closest thing water tech has to a working exit – and it is the backstory to how this company became the first and only water-tech unicorn in the first place.

Hasn’t water tech tried to go public before?

This is where the “zero public exits” in my title comes from, and it is the part that should worry anyone betting on the loop. Of those 5,531 deals in my database, the genuine public-market exits are a rounding error – barely a handful even mention a listing, and several of those are companies going the other way, taken private (H2O Innovation, for one). IPOs in the 2020s are a very pale echo of the 2010s. So the cord almost always gets cut somewhere other than a stock exchange.

Look at what Madrid was actually talking about and you see the shapes that work. Evoqua was built by private equity, taken public, then sold to Xylem for $7.5 billion. Ovivo’s electronics arm went to Ecolab for $1.8 billion. Seven Seas Water passed from one infrastructure fund to the next. And Axius Water, a platform private equity bolted together in barely five years, was sold to CRH – a building-materials group, a true wildcard from outside water – just two weeks before the summit opened. The path to a public exit does exist, mind you: NanoH2O sold to LG Chem and then on to Glenwood for $1.2 billion, and De Nora actually rang the bell, a story I told in how De Nora went from zero to IPO in seven years. It is just that, so far, it is the exception that proves how rare the rule is.

What is the “missing middle” trying to route around the drought?

While the exit door stays jammed, capital is busy trying to build its own. Aurelia Carrère, Thematic Chair at Summa Equity, calls her play the “missing middle”: a platform that buys companies in the gap between early-stage venture and the big buy-outs, scales them with utilities, and goes deliberately deep on one theme – emerging pollutants, and PFAS-destruction in particular. Her targets are concrete.

Summa starts from a platform doing roughly €5 to €10 million of EBITDA and builds up, the same way it already runs a waste-management platform across the Nordics. What I like about Aurelia’s framing is that she ties her private-equity missing middle to a missing middle in water itself – the same empty middle of the company landscape that Guillaume Clairet of H2O Innovation has been describing for years (we compared notes on it off the record in a Madrid corridor – hi Guillaume!), and the gap I went hunting for across 2,587 water companies in my own newsletter. The hole in the cap table and the hole in the company map turn out to be the same hole, seen from two sides. If you want that thesis in full, it runs right through the H2O Innovation acquisition playbook and my 2,587-company investigation.

Xylem is solving the same problem from the opposite end. Rather than pick early winners itself, it acts as a limited partner – a fund of funds – inside specialists like Burnt Island Ventures, using them as what Sivan Zamir, now Xylem’s Chief Innovation and Product Officer, calls the “top of the funnel.” Two very different firms, both engineering a way to manufacture the exit the public market is not providing. That is what an immature ecosystem looks like when it refuses to sit still.

How mature is the water investment ecosystem, really?

So I asked everyone the same blunt question: on a scale to ten, where is this ecosystem? The answers were a Rorschach test. Job van Schelven of Pureterra Ventures, ten years in, said three, maybe four. Aurelia called the system’s maturity “globally high.” Sivan was “really bullish.” And Anurag, who arguably built the biggest thing in the room, was the harshest of all: a three, maybe a four, against a Silicon Valley he puts at eight or nine. His arithmetic is the one I keep.

A single Gradiant IPO, he reckons, would move water from a three to a six. To get to an eight or a nine, you would need a few of those – not one fairy tale, but a track record. That is the whole thesis in one number. The capital is here, the platforms are here, the talent is here. What is missing is proof, repeated enough times that nobody can call the first one a fluke.

So, is the inflection point in the room?

After three days in Madrid I tried to argue myself out of it, and I could not. We are living through the most active capital chain the water sector has ever had. The growers have dry powder, the rotation operators are running at a record pace, the strategics are paying premium prices for de-risked platforms, a genuine wildcard like CRH just walked in for the first time, and the sector’s only unicorn doubled its valuation while talking IPO out loud. For the first time, I would not laugh that idea off the stage. I am not saying it is a good idea either – the jury is still out – but that is not a sector waiting for an inflection point. That is a sector living inside one.

But being at an inflection point is not enough. A chasm is something you cross – would make a good title for a book – because if you do not cross it, you die in the middle. All the scaffolding is in place, and it is also still very fragile. The next twelve months will not be decided by how much money flows in; that part is solved. They will be decided by whether one company, probably this one, can finally turn the yo-yo into a water wheel and cut the cord in public. Watch that door. The full conversation is worth your time – and if you want to hear all six investors make their case, the episode is right here.

Frequently asked questions

Will Gradiant IPO?

Gradiant is, in CEO Anurag Bajpayee’s words, “pretty close to being IPO-ready,” completing its reporting and compliance work and watching the market. No date has been set. He frames going public as the way to control the company’s destiny and give shareholders meaningful liquidity, while noting that a viable private secondary market already lets early backers cash out.

Is Gradiant the first water-tech unicorn?

Yes. Gradiant is the water sector’s first and only unicorn, and after its 2026 Series E it became a two-time unicorn at a $2 billion valuation – the raise itself was undisclosed.

Why are there so few water-tech IPOs?

Of the 5,531 completed water deals in my Leviathan database since 2015, genuine public-market exits are a rounding error, and IPOs in the 2020s are a pale echo of the 2010s. The track record is thin, so water companies almost always exit through a strategic sale or a private-equity-to-private-equity handoff rather than the public market.

How big is private equity in water now?

Private equity ran about 37% of all water deals in 2025, up from roughly 14% in 2015, with 165 acquisitions in the year – a record. Most were small: 80 of the 165 targeted companies worth under $10 million. The bench of PE-owned water platforms has grown from 42 in 2015 to nearly 600.

What is the “missing middle” in water private equity?

It is the gap between early-stage venture funding and large buy-outs – companies at roughly €50 to €150 million of revenue that need a platform to scale. Summa Equity is building specifically in that band, starting from platforms doing €5 to €10 million of EBITDA and focusing on emerging pollutants like PFAS.

The post Will Gradiant IPO? 600 Water Bets, Zero Public Exits appeared first on (don't) Waste Water.

By my count, the fifth most active water tech investor on the planet is not a water fund. It is the venture arm of a 100-year-old, family-owned asphalt-and-quarries company from Indianapolis, and water is barely a fifth of what it does. HG Ventures has backed 12 water rounds across 7 companies in my Leviathan database, which puts it behind only Burnt Island Ventures, Echo River Capital, PureTerra Ventures and Emerald Technology Ventures, every one of them a dedicated water specialist. HG is the only corporate venture arm in that top five. And here is the part I can say that nobody else can: I have sat down with the founders of five of the seven companies HG backs. So let me show you the fund through the people I have actually interviewed.

Who are the most active water tech investors in 2026?

When I rank every investor in my Leviathan database by the number of water rounds they have joined, the order at the top is Burnt Island Ventures with 48, Echo River Capital with 23, PureTerra Ventures with 16, Emerald Technology Ventures with 15, and then HG Ventures with 12.

Deal count here just means the number of distinct rounds an investor has joined, which is the cleanest way I know to measure how active someone really is rather than how loud they are. I have had every one of those four specialists on the podcast, and to a fund they exist to do water and nothing else. Then there is HG, a corporate fund most people in water have never heard of, keeping their company while calling itself something else entirely. That is the puzzle, and it is worth taking apart.

What is corporate venture capital, and why does HG’s version work?

Corporate venture capital, or CVC, is venture investing run from inside an operating company instead of from a standalone fund. A normal fund raises money from outside backers, the limited partners, and has to hand it back with a profit on a clock that usually runs about ten years. A CVC invests the parent company’s own balance sheet, and the textbook knock on it is the four-year curse: most corporate venture arms get quietly shut down around year four, the moment the parent loses patience.

HG sidesteps that curse by structure, and Ginger Rothrock, who runs the fund as Managing Director, put it more plainly than I could.

So while a classic fund is counting down to the day it has to sell, whether or not selling is good for the company, HG can simply wait. No limited partners, no clock, no forced exit. (I made an unpopular but honest case about this kind of money once, if you want the argument in full.) When you are a century-old family business, patience is not a strategy you adopt, it is just who you are.

Why a fund this small still chases returns

There is a second objection, and Ginger raised it before I could. Plenty of corporate venture arms exist purely as strategic antennae, where the money barely matters against the parent’s core business. She is candid that HG is a different animal, and the reason is size. She pointed to a friend at Samsung’s venture arm who did a three million dollar deal, got 20x, and handed back sixty million, and Samsung, a company that ships phones and televisions by the container-load, barely noticed.

A strategic CVC like that is mostly motivated to help the parent sell more product. HG is small enough, in pure dollar terms, that the money it returns to The Heritage Group matters just as much as any strategic value, which is precisely why it behaves like a real investor rather than a corporate science project. That, more than anything, is why it out-deal-flows the funds around it.

There is a fair objection here. If water is only 18% of HG’s thesis, how does it out-invest funds that do nothing else? When I analysed 1,425 water investors last year, I found that 86% of them put less than a tenth of their portfolio into water, and the median allocation was a thin 6.7%. In water tech, I wrote at the time, you are either a tourist or a specialist, and almost never a resident. (If you want the detailed maths on the three investor tribes hiding in that data, I dug into it on my newsletter – consider subscribing.)

By those numbers HG is a tourist, water a slice rather than the whole pie. The trick is that it behaves like a resident, and that has almost nothing to do with how much money it points at water and almost everything to do with the kind of money it is, and where it chooses to spend it.

From an incinerator to a water thesis

HG’s first water cheque was never meant to be a water strategy. It was a waste problem. The Heritage Group used to own and operate an incinerator through its environmental arm, and around 2019 Ginger’s team watched the PFAS-laden waste streams come in and simply not slow down. PFAS, the “forever chemicals” now turning up in drinking water across the world, were arriving by the truckload and were not going anywhere.

So they went looking for anyone working on the contaminant itself, and found exactly one company.

From that single waste-driven bet the thesis grew outward into industrial wastewater, water reuse, and zero liquid discharge, the extreme case where a plant recovers essentially all of its water and discharges almost nothing. (here is the economics pushing industrial water reuse) Three of HG’s seven water companies sit somewhere on the PFAS spectrum, which tells you the origin never really left.

HG’s water portfolio is, basically, my guest list

This is where I can do something no other write-up of HG can. Across those 12 rounds sit 7 companies and a little over 190 million dollars of total financing, and HG itself has deployed exactly 48,523,663 dollars into water, a figure I got confirmed straight from the firm, to the dollar, which is the kind of number no public database will hand you.

Five of those founders have sat across from me. Alex Rappaport built ZwitterCo around a membrane meant, in his words, to “solve the Achilles heel of filtration: fouling, clogging,” which is exactly the bottleneck that makes industrial water reuse so hard. Julie Bliss Mullen started Aclarity to destroy PFAS rather than just trap it, the way she had degraded other contaminants in her PhD: “they all could be degraded, and I did it electrochemically.” And Emily Hicks at FREDsense moved her field water test onto “a polymer based on a plant material that binds PFAS,” selective enough that, when it grabs the molecule, it releases a fluorescent dye she can simply measure.

The other two interviews show how wide HG’s idea of water actually runs. Megan Glover scaled 120Water, the one HG has since partly exited, on a sharp insight that the lead-in-water crisis is really a software problem: “the contaminant is lead, but at the root cause it’s a data management issue.” And back in 2020, Ari Raivetz told me that Transcend’s software “automates the first 20 to 30% of the engineering of a water or wastewater treatment facility,” cutting the grunt work out of plant design. Puraffinity’s PFAS media and ElectraMet’s metal recovery round out the seven. Patient money, pointed squarely at the unglamorous, regulated, industrial end of water.

What does HG offer a founder besides a cheque?

Notice what those five companies have in common beyond a logo on HG’s website: each one needs to prove a technology works on real, ugly, industrial water before a customer will trust it. That is exactly where a corporate parent stops being a handicap and becomes the product.

HG’s one-line thesis is to invest where The Heritage Group can help, then actually help. A pure financial VC can wire money and make introductions, but it does not own the quarries, the asphalt plants and the environmental operations where a young water technology can be tested on genuinely difficult streams. That access is the edge HG sells, and it is a large part of why it wins deals against funds with deeper pockets.

How do you pitch a water tech VC like this one?

Now the part founders most need to hear, because it runs against instinct. The person deciding whether to back you is a PhD chemist with The Heritage Group’s R&D labs down the hall, so you would expect her to lead with the technology. She puts it last.

The single thing she sees founders get wrong is not knowing who their real competition is. And the kindest thing an investor like this can give you is speed, a point Simon Olivier of Cycle H2O made to me from the other side of the table: he would rather founders “come to us early or earlier,” and if they are not ready, send them off to coaching than leave them hanging. For a founder chasing a cheque, a fast no can be almost as useful as a slow yes, and on that front HG is unusually quick.

The same-day yes or no

That speed is not a figure of speech. HG runs all of its diligence in-house, with no outside consultants, and the front of the process is brutally quick. A first call lasts half an hour. Then the founder goes in front of the entire investment group for an hour, back and forth, and HG decides that same day whether it is going into diligence at all.

If the answer is yes, one partner becomes the diligence lead and chases down two or three go/no-go questions straight away: is the revenue real, does anyone actually care about this, and is it a fit for The Heritage Group. Only then does it open into the fuller process, which almost always includes a technical session with experts pulled from inside the group. For a founder, that combination, a fast verdict and a hundred years of industrial muscle behind a yes, is rare enough to be worth pitching for.

Is water actually a good long-term investment?

This is where the patient money starts to look less eccentric and more correct. The public market has been an unkind place for small water technology companies, and the real returns have been accruing quietly in private rounds instead. In my database, the early-stage cheques where investors like HG actually live, the pre-seed to Series A rounds, more than tripled, from 33 in 2018 to 109 in 2025.

That is a 3.3 times jump, and it comfortably outruns the broader market of all water rounds, which only doubled over the same stretch. So the demand for capital is real and growing fastest exactly at the stage HG plays. The open question is the exit: water has produced very few of them, and a fund on a ten-year clock has to sell whether or not a buyer has shown up. (the rare escape is how Gradiant became the first and only water tech unicorn)

This is where HG’s lack of a clock turns into a quiet superpower, and where it has already done something most water investors are still waiting to do: it booked an exit. When 120Water raised its 43-million-dollar Series B in early 2024, HG sold down its stake “with a good multiple,” as Ginger put it, rather than riding along. The reasoning was telling. 120Water is a municipal software company, and as she said, “we don’t do municipal, we don’t know a lot about the areas in which they operate, so part of it was just fit,” while her first fund needed to start returning money: “we need to get some exits. There was an opportunity to get some liquidity, so it worked. We still have some ownership.” That is the asymmetry in one move. HG never has to sell, so when it does, it is because the fit is wrong and the price is right, not because a clock ran out. It is the whole reason the most active investor on my list is the one under no pressure at all.

The one-word thesis

When I asked Ginger for her one-word thesis on water, the answer came back as “inevitable.” After nine years of out-deal-flowing funds that do nothing but water, that lands a good deal heavier than the bumper sticker it sounds like. The harder question is what happens when all these private bets finally need a way out, in a sector that has barely produced one, and that is the conversation Ginger and I have in full on the episode.

Frequently asked questions

Who are the biggest water tech investors in 2026?

By number of water rounds in my Leviathan database, the most active are Burnt Island Ventures, Echo River Capital, PureTerra Ventures, Emerald Technology Ventures, and HG Ventures. The first four are dedicated water funds. HG Ventures, the corporate venture arm of The Heritage Group, is the only corporate investor in the top five.

What is corporate venture capital (CVC)?

Corporate venture capital is venture investing run from inside an operating company rather than an independent fund. Because the parent is not on a limited-partner clock, a CVC like HG Ventures can hold a company for a decade or more without being forced to sell, which is why it can behave more patiently than a traditional fund.

How do you pitch a water tech VC?

Lead with the story, not the technology. HG Ventures screens first on whether a founder can explain the market, name their real competition, and tell a clear, articulate story. Founders who open with the technology tend to lose, and at HG the decision to enter due diligence can come the same day you present.

Is water a good long-term investment?

Water demand is structural, but the returns mostly sit in private markets rather than public ones, where small-cap water stocks have a long record of drifting down after their IPO. Early-stage private water rounds more than tripled between 2018 and 2025, which is where specialists and corporate venture arms like HG Ventures concentrate.

What are industrial water reuse and zero liquid discharge (ZLD)?

Industrial water reuse means treating a plant’s own wastewater on-site and recycling it back into the process. Zero liquid discharge is the extreme version, where essentially all of the water is recovered and almost nothing is discharged. Rising freshwater costs, tightening discharge rules, and corporate ESG targets are pushing both up the agenda.

The post How HG Ventures Quietly Became a Top-5 Water Tech Investor appeared first on (don't) Waste Water.

Every water utility on earth still validates its drinking water roughly the way it did in 1887: take a sample, smear it across a petri dish, and wait about 72 hours for the bacteria to grow numerous enough to count by eye. Which means the “real-time” dashboard your local utility is so proud of is, in plain terms, reporting on what died in the water last Tuesday. That three-day blind spot is one of the most expensive habits in the whole water industry, and killing it is the entire premise of real-time microbial monitoring. On episode 21 of season 13, I sat down with Lorenzo Falzarano, the founder of Orb, who builds inline sensors that count microbes in seconds instead of days. His framing is blunt: if artificial intelligence is the water sector’s shiny new brain, somebody still has to build the optic nerve. So here is why the eyes have been missing for 140 years, what running blind actually costs, and why the money is finally starting to pay attention.

Why are water testing methods so dangerously outdated?

Start with the uncomfortable fact. The reference method for deciding whether your tap water is safe, the culture plate, was invented in 1887, the same decade the motorcar started elbowing the horse off the road. You take a sample, you put it in an incubator, and you wait roughly 72 hours for colonies to grow visible enough to count by sight. By the time the answer lands on someone’s desk, that water is long gone, drunk or discharged or pushed into a river. We have spent the last few years building digital twins and bolting artificial intelligence onto everything that holds water, and the whole sophisticated apparatus is still being fed a number that describes the past. As Lorenzo puts it, we are running the global water system on a 3-day delay.

Culture method (the petri-dish test): you take a water sample, place it on a nutrient plate, and let any microbes multiply for one to three days until the colonies are big enough to see and count. Accurate, cheap, and almost 140 years old. Its flaw is time: the result describes the water as it was, not as it is.

The hidden cost of running a water plant blind

Now, running blind is not free. It is just an invisible line item, one I would call the safety tax. Because operators cannot see the biological load in real time, they default to the worst case: overdose the disinfectant, run the ultraviolet lamps at full tilt, hold extra contact time, all just in case. When I dug into the numbers behind this episode, I found a single 100,000 cubic-metre-per-day plant burning roughly $21,000 every single day in excess chemicals alone, which works out to about 6% of its total operating cost, spent purely to maintain a safety buffer against a risk nobody could measure. Run the UV lamps flat-out when the water is already clean and you waste something like 15% of that energy. And because overdosing creates extra sludge, and sludge handling can be 40% of a plant’s operating cost, you end up paying to manufacture waste you then pay again to haul away.

I once described this whole dynamic, in a newsletter, as the reason you walk slower across a dark hotel room: take away the sense you normally use to avoid risk, and you overcorrect on everything else. I wrote about why, in this gold rush, the smart move is to sell shovels.

What happens when nobody finds the source?

And the safety tax gets a lot more expensive when things actually go wrong. Lorenzo drops one statistic that sums up the entire crisis: by Orb’s reckoning, around 70% of water contamination investigations end as cold cases, where the utility never finds the root cause. Why? Because without high-resolution data, you are working a crime scene three days after the evidence washed downstream. Regulators have started pricing in that blindness directly. In 2025 the UK regulator Ofwat hit Thames Water with a £104.5 million penalty over failures across its sewage operations. And when cryptosporidium broke out in Brixham in 2024, the contamination cost the Pennon group £16.3 million and put roughly 16,000 homes under a boil-water notice for weeks. That was not the cost of fixing the damaged valve that let the parasite in. It was the price of not knowing the valve was broken until thousands of households were already drinking the consequences.

What is real-time microbial monitoring, really?

So here is the precise gap Orb is built to fill. At a treatment works today, operators mostly watch two things: turbidity and chlorine. Neither one tells you what is actually alive in the water, and many times there is no correlation between a turbidity reading and the real microbial load. Yet by Lorenzo’s account, the top five of the ten most common water-quality standard failures are all bacteriological, meaning they are about living organisms, the coliform bacteria and E. coli that flag something unsafe has slipped through, rather than the chemistry. Sit with that for a second: the single biggest reason plants fail their standards is the one thing almost nobody monitors live.

Turbidity: how cloudy the water is, measured by how much light it scatters. It is a useful, cheap proxy for “something changed,” but it is a health-blind one, a clear glass of water can still be teeming with bacteria.

How does Orb count microbes in seconds, not days?

So how do you compress three days into three seconds? Instead of growing bugs on a plate, Orb shines light at the water and reads the way microbial cells fluoresce, glowing back a little brighter than the plain water around them, and counts them as they flow past. No reagents, nothing consumed, nothing destroyed, just photons doing the work. The reading comes back in about three seconds instead of three days. Orb’s website pushes a sharper number, claiming the method is roughly 1,700 times faster than the incumbent way of counting microbial pollution, and you can take the exact multiplier as the marketing line it is, because the part that actually matters is the change of category, from days to seconds. And the sensor is only half of it: the signal feeds an intelligence layer that does not just tell an operator their bacteria count jumped, it points at the most likely reason it jumped. Making all that data legible to the people actually running a plant is its own hard problem.

Fluorescence sensing: certain molecules absorb light at one wavelength and re-emit it at another. Living microbial cells, rich in proteins and amino acids, fluoresce in a tell-tale way, so an optical sensor can count them in flowing water without any chemical reagents, in real time, instead of waiting for a culture to grow.

Lorenzo is candid that this means building hardware, which is exactly the thing most investors would rather avoid. But you cannot have a smart-water revolution without it. I have argued before that measuring water quality is, awkwardly, a hardware problem dressed up as software.

Orb is not chasing the petri dish alone

And no, reassuringly, this is not one company shouting into the void. The whole frontier is racing the same near-140-year-old plate, which is the best possible sign that the problem is real. On my own podcast I heard the identical complaint from a completely different angle when Sam Dukan walked me through Diamidex, whose MICA system delivers an E. coli result in 6 hours instead of 24, and a Legionella result in 2 days instead of the usual 10, while matching the standard method exactly. Different physics, same enemy: the clock.

There is a small ecosystem forming here, and I have hosted more of it than I expected. FREDsense, for instance, is chasing the same goal with an electrochemical biosensor.

Is real-time water monitoring actually a market yet?

This is where it gets genuinely interesting for anyone who deploys capital, and where my day job collides with my podcast. When I ran the numbers across my own Leviathan database, the entire peer set of real-time water-quality biosensing companies, the ones genuinely doing what Orb and Diamidex do, has raised only about $97 million across 54 rounds, ever. No single round in that group tops roughly $12 million. To put that in perspective, that is the whole category raising, across its entire history, less than a single mid-size Series B in almost any other deep-tech vertical. This is not a crowded gold rush. It is a frontier that has barely been funded at all, which is either a warning or an invitation depending on your temperament.

The shape of that line matters more than the total. For years the category raised single-digit millions and looked like a science project. Then 2024 and 2025 happened, and last year alone the peer set pulled in $34.4 million across 11 rounds, its busiest and best-funded year ever. The money is, finally, starting to notice the eyes are missing. I track where water-tech capital actually goes in my state-of-funding work. If you want the running version of this, I send it out in my newsletter.

Water reuse is ending water’s three-day grace period

So why now, after 140 years of the industry shrugging at the three-day lag? Because the future of water is reuse, and reuse quietly demolishes the old excuse. You cannot recycle water through faster and faster treatment cycles while waiting three days to confirm a batch is safe. By the time your culture result comes back, you are storing three-day-old water in a tank, which, as Lorenzo points out, is arguably worse than the water you started with. The moment treatment cycles get short enough, real-time validation stops being a nice-to-have and becomes the gate that the whole process has to pass through.

Frequently asked questions

How is drinking water tested for bacteria?

The standard method is the culture, or petri-dish, test: a water sample is placed on a nutrient plate and any microbes are left to multiply for one to three days until the colonies are large enough to count by eye. It is accurate and cheap, but slow, the result describes the water as it was up to 72 hours earlier.

How long does water quality testing take?

For the classic culture method, one to three days. Faster lab techniques have cut that sharply, Diamidex returns an E. coli result in about 6 hours, and real-time inline sensors like Orb’s read microbial signals in seconds. The trade-off has historically been between speed, cost, and how closely a method matches the regulatory gold standard.

What is real-time microbial water monitoring?

It is the continuous measurement of the living, microbial load in water using inline sensors, rather than sending samples to a lab. Reagent-free optical sensors count microbes as the water flows past and feed the readings to software that flags trends and, increasingly, the likely root cause of a contamination event.

Why is real-time water quality monitoring important?

Because the three-day lag is expensive in two directions. It forces operators to overdose chemicals and energy as a precaution (the “safety tax”), and when contamination does happen, roughly 70% of investigations never find the source. As water reuse spreads, instant validation of each batch becomes unavoidable.

What is coliform bacteria in water?

Coliforms are a broad family of bacteria used as an indicator of water quality: most are harmless, but their presence signals that conditions could allow harmful organisms through, and some, like E. coli, point to faecal contamination. Coliform failures are among the most common reasons a treatment works breaches its standards.

Is real-time water monitoring a good investment?

It is early and thinly funded. By my count across the Leviathan database, the real-time water-quality biosensing peer set has raised only about $97 million across 54 rounds in total, with no single round above roughly $12 million, but 2025 was its biggest year yet. Small market, fragmented field, accelerating demand: make of that what you will.

The eyes are finally being built

For 140 years the water industry got away with testing for life by waiting for it to grow. Reuse, regulation, and the simple cost of running blind are quietly ending that grace period, and the companies building water’s missing eyes are still cheap, few, and early. Whether Orb is the one that wins is an open question. That the eyes are finally being built is not. Go listen to my full conversation with Lorenzo Falzarano, it is worth your hour.

The post Real-Time Water Quality Monitoring vs the 1887 Petri Dish appeared first on (don't) Waste Water.

This looks like a solar panel, but it’s really a water tap, one that needs no pipe, no grid, no connection to anything, and still pours out enough clean, mineralized water for two people, all year long. Unless it’s freezing, or too cloudy, or raining too hard, or the unit just breaks. SOURCE Global built that machine, called it a Hydropanel, and convinced Bill Gates, Jeff Bezos, BlackRock and Microsoft to pour roughly $270 million into it. That makes SOURCE one of the three most-funded water-tech companies there has ever been, by my count in my Leviathan database. And then, in about twelve months, it went quiet and died. So what actually kills a company that raised that much, from investors that smart? Three things, mostly: it ran out of cash and couldn’t raise more, its panels started breaking faster than it could fix them, and the pivot meant to save it came too late. Let me walk you through how.

What did SOURCE Global actually build?

So let’s start with the machine, because it really is a beautiful idea. A Hydropanel is a solar-powered box that pulls water vapour out of the air, condenses it into liquid, and mineralizes it into drinking water, with no connection to a grid or a pipe. That’s atmospheric water generation, AWG for short: making water from thin air. The company behind it was founded in 2014 in Arizona as Zero Mass Water, and renamed SOURCE Global in 2020. Its founder, Cody Friesen, is an MIT-trained materials scientist who collected just about every innovation prize going, from MIT’s Innovators Under 35 to the Lemelson-MIT Prize. And when I rank every water-tech company by the funding I’ve logged in my Leviathan database, SOURCE comes in third, behind only Gradiant and Lilac Solutions. It’s the only company in that top tier that’s now dead.

Raising $270 million was the easy part

Here’s the thing about fundraising milestones: they get cheered as proof a company is winning, but they’re really just proof it needed cash. No founder gives up equity for fun. The way I think about it, venture money is nitro for your engine: you use it to grow faster than you naturally can, while hoping the car doesn’t explode before you’ve finished building it. SOURCE strapped on four bottles of nitro. It raised about $22 million in a Series A in early 2018 (a startup’s first big institutional round), another $20 million in a Series B the same year, $50 million in a Series C in 2020 led by BlackRock, and then the big one, a $130 million Series D in 2022 led by Bill Gates’ Breakthrough Energy Ventures. Each later round is a bet on the last one’s promise paying off. So the real story of SOURCE isn’t the money. It’s the promises that money was bought with, and whether they came true.

Did the technology actually work?

For a while, genuinely, yes. The first promise, back in 2018, was to “leapfrog infrastructure just as cell phones do”: if piping water to people is too expensive, decentralize it instead, and bring it straight to whoever needs it. And SOURCE delivered the proof. It donated Hydropanels to Puerto Rico after Hurricane Maria, dropped them in the middle of nowhere in Australia and Syria, put them on pediatric wards in Jamaica. It closed that first funding cycle with a bold rollout in Neom, Saudi Arabia, and later deployed across the Navajo Nation, the Philippines and Colombia, reaching references in 54 countries. Nobody expected those panels to be cheap or eternal yet; they expected a proof of concept, and then a proof of market, and they got both. Then, on my own podcast microphone in 2022, SOURCE made the promise that would come to haunt it.

The Hydropanels couldn’t survive the field

To chase “the cheapest water on Earth,” SOURCE had to cut costs, hard. So it built a 400-person plant in Penang, Malaysia, and moved to as many cheap parts and materials as it could. The trouble is that making cheap parts that still work is its own skill, and from the former employees I heard from on both sides of the Pacific, that didn’t go smoothly: constant plan changes, indecision from the top, and at the Malaysian facility, a churn of layoffs and rehires that wrecked consistency. Quality slid. The most documented case is Allensworth, California, where panels bought to fix arsenic-tainted groundwater ended up sitting broken in people’s yards. But here’s what makes it sting: just a couple of years earlier, on that same microphone, SOURCE had promised those panels would last two decades.

How long do SOURCE Hydropanels actually last?

Not twenty years. That was the marketing. Quietly, a couple of years later, SOURCE walked the commitment back to five years of support. And in the field, plenty didn’t even make that: in 2024, the local outlet SJV Water reported that in Allensworth, two years in, many residents had pulled the Hydropanels out of their yards because they’d stopped working and were just taking up space, with the maintenance crew, in the company’s own words, thinned by “high turnover.” It’s worth remembering that as far back as 2018, the YouTuber Thunderfoot had done the brutal arithmetic in a video literally titled “Zero Mass Water busted”: at around $4,500 for two rooftop panels, you could have a tanker truck haul you the same water from the other side of the country over the panels’ lifetime, and still pay five times less.

What were the warning signs the money was running out?

The first tell wasn’t a press release. It was silence. SOURCE’s backers have famously deep pockets, Breakthrough Energy Ventures, Microsoft’s Climate Innovation Fund, BlackRock, so when they declined to throw in a bridge (a small, short-term top-up, usually at the last round’s price, from investors you already have), that alone said something. Then the rumour started going around the small world of water investors that SOURCE was raising a down round: new money at a lower valuation than before, which dilutes and devalues the existing investors twice over, and which usually either closes within weeks or never closes at all. For months, it was crickets. Then, in April 2025, an SEC filing surfaced showing SOURCE trying to raise $75 million and having sold just $19.3 million of it. The name at the top of that filing wasn’t Cody Friesen. He’d vanished from the document entirely. I reached out to him at the time, and didn’t hear back.

Why did a water-from-air company start canning water?

This is the part that sounds insane until it doesn’t. In 2023, SOURCE bought Proud Source Water, a bottled-spring-water brand, and launched Sky Water: canned water made from its Hydropanels. A company that had spent years arguing bottled water was the problem was now… selling cans of water. But it’s a page straight out of the Xerox playbook. When the Xerox 914 copier proved too expensive to sell in the 1960s, Xerox stopped selling the machine and started leasing it, charging per copy; customers bought the output, not the hardware. Selling canned Hydropanel water could, in theory, do the same: create steady volume for the factories while the panels stayed in SOURCE’s own hands. The problem is that beverages are brutal: by industry counts, 90% of beverage startups fail within two years, and the move needed marketing cash SOURCE no longer had.

So is SOURCE finally, fully dead?

By my read, effectively yes. SOURCE posted to LinkedIn near-daily, then stopped dead on the 27th of February 2025; my own liveness scoring in the Leviathan database flags that as a silence ratio of nearly 200 against a critical threshold of ten, and scores the company dead at 0.90 confidence. The executives updated their profiles to “open to work” through the spring, the products went out of stock, and source.co quietly carried on as a Shopify storefront on autopilot. The one apparent survivor was Proud Source Water, still selling, seemingly near breakeven, the closest the SOURCE empire ever got to profitability. Then, after I published this story, readers from Mackay, Idaho, where Proud Source bottles its water, wrote to tell me that plant had closed too. I haven’t been able to confirm it independently, and public listings still show the brand active, so treat it as a developing thread, not a settled fact. But if it’s true, even the lifeboat sank.

SOURCE’s death doesn’t doom atmospheric water generation

It’s tempting to read it the other way, that the best-funded one died so the rest are doomed, but the data says otherwise, and I dug into exactly this in my newsletter follow-up to the episode. By my count, since SOURCE raised its Series A in 2018, seventeen other AWG companies have raised growth-stage money, roughly $120 million between them, and nine of those raised in 2025 alone, backed by genuinely water-savvy investors like Burnt Island Ventures and Echo River Capital. The difference is that they mostly avoid SOURCE’s original sin. You can make water from air, you can do it fully off-grid, and you can sell it cheaply to consumers, but you only get to pick two of those three. SOURCE tried for all three at once. The others picked their two.

Was SOURCE a scam?

Also no, and the distinction matters. A scam is Theranos: Elizabeth Holmes went to prison because she *knowingly* deceived. SOURCE’s loudest critics were never hidden, Christopher Gasson at Global Water Intelligence called it an “egregious waste of money” in print, and the analyst Rhys Owen said flatly that it was overvalued, both of them one Google search or one phone call away from any investor doing diligence. What actually fooled people was subtler, and almost poetic: the Hydropanel looked like a solar panel, so investors assumed solar’s plummeting cost curve would apply to it too. It won’t. There are hard thermodynamic floors on pulling water from air that no amount of scale erases. SOURCE, in the end, confused thermodynamics with a religion.

What should a water investor take away from this?

Not a witch hunt. The temptation after a failure this loud is to start hunting for the next dodgy water-tech, and I’d push back on that. Water entrepreneurship is, frankly, an unreasonable endeavour, and if you leave it only to cautious water engineers (like me), you get nothing but incremental improvement, which at the scale of today’s water problems may simply not be enough. The lesson of SOURCE isn’t “stop dreaming.” It’s “dream rooted in the physics, not in spite of it.” Cody Friesen says a builder’s gotta build, and he’s already onto something new, so I’ll be watching for it.

Frequently asked questions

What does SOURCE Global do?

SOURCE Global makes solar-powered Hydropanels that pull water vapour from the air and mineralize it into drinking water, with no grid or plumbing connection. Founded in 2014 in Arizona as Zero Mass Water and renamed in 2020, it raised roughly $270 million but is now effectively defunct.

Who is the CEO of SOURCE Global?

Founder Cody Friesen, a materials scientist trained at MIT, led SOURCE until early 2025. Bill Witz took over as CEO in March 2025, and Friesen publicly announced he had left the company in June 2025.

Is SOURCE Global publicly traded?

No. SOURCE Global is a private company (a Public Benefit Corporation). Its last major raise was a 2022 Series D; an April 2025 SEC filing sought $75 million but had sold only $19.3 million.

How long do SOURCE Hydropanels last?

SOURCE originally marketed a lifespan of up to 20 years, then quietly reduced its commitment to 5 years of support. In the field, many units failed within two to three years, with reports of broken fans, dead batteries, and absent maintenance.

Is SOURCE Global still in business?

Barely. Its LinkedIn has been silent since February 2025, its products are out of stock, and its leadership has departed; my liveness scoring rates the company dead at 0.90 confidence. Its acquired brand Proud Source Water remained active, though one unconfirmed reader report says its Mackay, Idaho plant has since closed.

The post SOURCE Global: How a $270M Water Startup Died in 12 Months appeared first on (don't) Waste Water.

SKion Water is the water technology platform of SKion GmbH, the investment company of Susanne Klatten, and yes, that is the BMW heiress. It is, by my count, the most prolific private buyer of water companies you have never read a deal price for. My Leviathan database holds 32 SKion-family acquisitions from 2012 through 2024, Ovivo and Paques included, and exactly one purchase has a disclosed price. In December 2025, the quiet compounder did something loud: it sold Ovivo’s Electronics division to Ecolab for roughly 1.8 billion dollars in cash, about twelve times the only price it ever disclosed paying. Three months later, SKion Water’s CEO Reinhard Hübner took over as Ovivo’s CEO to rebuild it. I have had him on my podcast three times since 2022, so let us replay the tapes against my database: what he said, what he bought, why he sold, what comes next.

Who owns SKion Water?

SKion Water is a subsidiary of SKion GmbH, the wholly-owned investment company of Susanne Klatten, daughter of Herbert and Johanna Quandt and holder of about 19% of BMW. Said plainly: the BMW fortune has spent thirteen years quietly building a water empire.

The man running it never planned to be there. Reinhard Hübner is an operations guy with a PhD in mathematical optimization who spent almost two years inside Thames Water working on leakage, hired into SKion in 2010 because Klatten, as he tells it, did not want an investment banker running her water bets but somebody with an industrial background.

He built what finance people call a platform, a holding company that grows by buying companies and keeping them rather than flipping them, and it is evergreen: one family’s permanent capital, no fund clock. The first water moves in 2012 were minority bets, 20% of the Dutch biotech specialist Paques and a stake in Turkey’s Miranda, and only later was the portfolio grouped into SKion Water as one umbrella, as Reinhard tells it on my 2022 tape, after SKion was named Water Company of the Year.

How many water companies does SKion Water actually buy?

On my 2022 tape, Reinhard gave me the number: “We buy 4 to 8 companies every year. Some of them are publicly announced, some not, or just announced at the local markets…” My deduped Leviathan database shows 32 SKion-family acquisitions from 2012 through 2024, 17 direct and 15 through portfolio companies, with five-deal peaks in 2019 and 2022.

My count and his do not match, so let me walk the gap. The twelve months before the conversation I published in May 2024 show three on the public record: Sanpure in India, VIGAflow in Chile, E2metrix in Quebec. Reinhard says four; his own 2022 caveat reconciles it: some deals are never announced, and a public-record database structurally undercounts a buyer who does not brag. I also removed eight duplicate records my own pipeline had double-ingested before quoting anything (counting is harder than it looks, for me too).

A bolt-on is a smaller acquisition by a company you already own, and SKion runs on them: Ovivo alone made six since 2018, the same pattern H2O Innovation ran for 25 years.

What SKion looks for before it buys

“In a technology acquisition, you have to get your head around the technology,” Reinhard says, and he means it physically: sometimes SKion buys one unit of a machine and tests it before buying the company, and he once put on the gear for digester diving himself (a real job, look it up, and pray you never need it). The scope rule is just as plain: “At heart, we are a treatment company,” meaning water and wastewater treatment plus the services and consumables around it, and explicitly not pipes and networks.

And then there is the discipline rule, which is where his dry side shows, because some business plans he gets pitched assume revenue physics nobody has ever observed.

His own distinction is worth keeping: with a system integrator, the reference plants tell you whether they can do the job, while a new technology has to prove itself across many different applications before you can trust it.

Who sells their water company to SKion?

At least 9 of the 32 acquisitions in my database have a documented family or founder on the selling side. ENWA came from the Hanssen family explicitly as a succession-planning sale, GEAL from its two founders, Malmberg Water from a family-owned Swedish group, and the founders of Faxon and Sanpure both stayed on as shareholders. Succession, much more than auctions, is this platform’s native deal flow.

On the 2025 tape, Reinhard explained why that works, the closest thing to a sales pitch I ever heard from him. SKion will never be the highest bidder, he says, because it sells permanence instead: by his telling, nobody left Ovivo after SKion bought it off the stock market. Then comes the line I keep replaying.

A succession sale, to give it its name, is a founder or family handing over a business they cannot or do not want to run into the next generation, and it is the one situation where the buyer’s story can beat the buyer’s price. If you want to see who else hunts in that pond, I keep a map of every investor active in water tech.

What is the turnover of SKion Water?

There are no public filings, because SKion Water is private, so the only first-party numbers in existence are on my tapes. On the 2024 one, Reinhard told me: “If you take 2020 as a reference year, we almost tripled in turnover between 2020 and now. We were $500 million-ish in 2020. We’re $1.4 billion budgeted this year.” The 2025 tape adds the proof-of-method on one branch: EnviroChemie had 90 million euros of turnover when SKion bought it in 2013, and the group around it does 350 million today.

Stranger still is how little machinery sits on top. SKion Water is a decentralized holding, meaning the companies keep their names, management, and culture, and the center stays so thin that a group budgeted at 1.4 billion dollars had, by Reinhard’s own 2025 account, no group treasury at all. The price of that choice is real, since European reporting rules like CSRD assume a center that produces paperwork, so a SKion Water Academy now trains the companies instead.

Why did SKion sell Ovivo’s Electronics business to Ecolab?

On August 12, 2025, Ovivo and SKion announced the sale of the Electronics division (ultrapure water for chipmakers) to Ecolab; it closed December 16, 2025, for roughly 1.8 billion US dollars, all cash. For scale: the 2016 take-private, alongside Quebec pension fund CDPQ (30%), paid C$4.00 a share, about 185 million Canadian dollars (142 million US then), the only price SKion ever disclosed. Quick maths: 1.8 billion over 142 million means one division sold for over twelve times the entire company’s 2016 valuation.

Why sell, when the pitch is permanence? The market answer, 2025: “valuations have gone up to a level that personally I think long-term is not healthy,” which politely means: offered silly money, even a permanent owner does the math. His portfolio answer was already on my 2022 tape.

A carve-out is selling one division while keeping the rest; this one cut cleanly because semiconductor water shared nothing with its siblings; Ecolab’s release names its motive: a bigger position along the AI value chain. I dissected the consequences in What the Ovivo Deal is Changing for YOU, and the next one is a click away subscribe.

What happens to Ovivo now?

Three weeks before the deal closed, I sat with Reinhard and the Ovivo team, and he set a clock on the record: “In 10 years, Ovivo will be back at the size where it is today. No doubt.” The ingredients he names are specific: Cembrane’s silicon carbide membranes rolled out across the whole group, PFAS destruction as a second growth engine, and a North American industrial business modeled on Europe’s 350-million-euro EnviroChemie group, targeted at 200 to 300 million dollars. His timeline answer could come from a project manager: “Give me 18 [months], because first we need to close the transaction.”

The carve-out mechanics are unglamorous and he does not hide them: transition services, the contractual period where the seller keeps running systems for the buyer, people moving between entities, plus the odd bonus that Ovivo’s head office, drilled by listed-company years, now lends the group capabilities it never built. Then, four months after our conversation, came the kicker: on March 31, 2026, Reinhard himself took over as Ovivo’s CEO, succeeding Marc Barbeau, on top of his SKion Water duties. The man who opened my 2022 tape with “I’m not an investor” went from operator to investor and back to operator, and he owned his words doing it.

Scoring the slowdown promise, two years on

This has become a running gag between us, and I planted it in the episode’s cold open: every conversation with Reinhard or his colleague Dirk Brusis starts with some variant of “actually, we are slowing it down a bit.” Then, minutes later in the same conversation: “We did 4 acquisitions, there’s 2 more in the pipeline.”

So let us score the May 2024 claims with two years of hindsight. Pipeline deal number one materialized four months later, when Malmberg Water joined through ENWA in September 2024, a lovely Russian doll given that ENWA itself had only been bought the year before. Pipeline deal number two never surfaced publicly, which means it either quietly closed or quietly died, and I genuinely cannot tell you which. And 2025 closed with zero visible acquisitions and one 1.8 billion dollar sale, so the slowdown finally arrived, in the loudest way available to a quiet company, though his own wave theory (“you acquire and then at some point you also have to do the homework”) plus the 18-month rebuild clock say the machine restarts soon.

What does the EPA’s PFAS rule have to do with a German buyer?

On April 10, 2024, the US EPA announced the first federal drinking water limits for PFAS, the synthetic “forever chemicals”: 4 parts per trillion for PFOA and PFOS, with compliance due by 2029. A part per trillion is roughly one drop in twenty Olympic pools. Days later, at the Global Water Summit in London, Reinhard said the quiet part: “It’s hard to achieve and it’s impossible to pay for, but PFAS is a real problem…”

By May 2026, the EPA had come most of the way to his position, proposing to keep the PFOA and PFOS limits but extend compliance to 2031, and to rescind the other compounds’ limits entirely. The affordability call aged well, and it explains the buying: SKion first invested in, then acquired E2metrix, the Quebec electrochemical PFAS-destruction company, because destroying the molecule where you catch it beats trucking contaminated filter media around. On the 2025 tape, PFAS is an Ovivo rebuild pillar, with the know-how sitting squarely in North America (“nobody knows more about PFAS than these guys here”, and, as he corrected himself, girls).

The buyers’ leaderboard nobody publishes

Since I have the database open anyway, here is SKion next to everyone else, because the biggest buyers in water are not who you think. By distinct targets 2012 to 2025 in my Leviathan database, the volume kings are utility consolidators and point-of-use roll-ups: American Water 145, Essential Utilities 128, Waterlogic 99. A roll-up is the strategy of buying many small similar businesses to build one big one, and buying ten municipal systems a year, every year, is a different sport from buying technology companies.

Filter for the technology game SKion actually plays and the tier reads: Suez 48, the engineering consolidator Stantec 48, Evoqua 28 before Xylem absorbed it in 2023, and SKion right among them with 30 distinct targets across its 32 deals. One difference: every other name there publishes prices, files accounts, or answers to shareholders, while SKion discloses essentially nothing and answers to one family. Which is why you read it the way we just did: three tapes, four years apart, checked against a deal graph it never knew existed.

FAQ

Who owns SKion Water?

SKion Water is a subsidiary of SKion GmbH, the investment company wholly owned by Susanne Klatten, the BMW heiress and Germany’s wealthiest woman. It groups her water technology holdings (Ovivo, Paques, EnviroChemie, ELIQUO, Adasa, ENWA, and others) under one umbrella, led by Reinhard Hübner, who has run Klatten’s water investments since 2010.

What is the turnover of SKion Water?

No public filings exist. The only first-party figures are Reinhard Hübner’s statements on my podcast: roughly $500 million in 2020 and $1.4 billion budgeted for 2024, before the 2025 sale of Ovivo’s Electronics division removed a large semiconductor-water business from the group.

Who owns Ovivo?

SKion Water has owned Ovivo since the 2016 take-private (70% at first, 100% since 2020, after buying out partner CDPQ). Ovivo’s Electronics division was sold to Ecolab in December 2025; the rest of Ovivo remains a SKion Water company, with Reinhard Hübner as CEO since March 2026.

How many companies does SKion Water buy per year?

Reinhard Hübner’s own figure is 4 to 8 per year, including deals that are never publicly announced. My Leviathan database verifies 32 SKion-family acquisitions from 2012 to 2024, averaging about 2.5 visible deals per year with peaks of five in 2019 and 2022.

Why did SKion sell Ovivo’s Electronics business?

Two reasons on tape, one in Ecolab’s release: semiconductor ultrapure water shared zero overlap with the rest of the portfolio, valuations had risen to levels the CEO called long-term not healthy, and Ecolab paid roughly $1.8 billion in cash to extend its AI-and-semiconductor water platform.

Will Ovivo grow back after the Ecolab deal?

That is the stated plan: “back at the size where it is today” within ten years, built on Cembrane’s silicon carbide membranes, PFAS destruction, and a new North American industrial water business targeting $200 to 300 million in turnover, with Reinhard Hübner now running Ovivo directly.

The thing to watch is the deals nobody announces

I will leave you with the two bets Reinhard says come next. One is water recycling, since “the water is running out in many places,” and he now counts Germany among them, a sentence he admits he never expected to say. The other is modular, off-site plant building, factories assembling treatment plants from forty-foot modules so nobody has to run a multi-year construction site inside a customer’s facility. Map those two onto a fragmented industry where maybe a hundred companies worldwide have the profile to become platforms (I ran that screen in my newsletter, and the bottleneck is real), and you get a fairly precise picture of SKion’s next decade: more family successions, more quiet local-market deals, and somewhere down the line, the rebuilt Ovivo proving the model twice. The press releases will tell you almost nothing, and that is rather the point: with SKion Water, the deals worth knowing about are precisely the ones nobody announces, which is why I will keep my database open and the microphone on.

The post SKion Water: 32 Quiet Deals, One $1.8 Billion Loud Exit appeared first on (don't) Waste Water.

And here is the part that makes this more than a nice growth story: under private equity ownership, the buying has not stopped. So how does a mid-cap company actually out-buy the giants, and what happens when someone bigger buys you? Guillaume Clairet, H2O Innovation’s COO, walked me through the whole machine on the podcast, and I ran his claims against my own M&A database. They check out, and then some.

H2O Innovation: three pillars, one new owner

Founded in 2000 in Quebec City, H2O Innovation runs three pillars: water treatment systems, specialty chemicals and consumables, and operation & maintenance services. In December 2023, the private equity firm Ember Infrastructure took the company private at C$4.25 per share, a premium of roughly 68%, ending more than two decades on public markets.

Now, “take-private” is one of those finance terms that sounds more dramatic than it is: a buyer purchases all the publicly traded shares, the stock gets delisted, and the company keeps operating with one owner instead of thousands. What it changes is the clock speed. A public board answers to quarterly earnings, and a PE owner answers to a five-to-ten-year plan. And if you wonder why a fund came knocking in the first place, Guillaume’s answer is refreshingly unstrategic: they met the way everyone meets in this industry.

Rare asset is not him bragging, by the way. A $200 to $300 million water company sits in a strangely empty part of the market, as he puts it: “there’s really big ones and then the tiny ones.” I found that empty middle fascinating enough to once dig out the yearly revenues of 2,587 water companies and map it myself I Investigated 2587 Water Companies, and if you would rather not miss the next edition, subscribing costs you exactly one click subscribe. That scarcity is also what put H2O Innovation on the radar of private equity funds hunting in water.

How many companies has H2O Innovation acquired?

As you know, I’m fun at parties, so I’ve taken down every M&A move that closed in the water sector since the year 2000 and turned it into a section of my Leviathan database. So when Guillaume started counting acquisitions on the podcast, I checked (to get additional clarity, you understand) and found 19 water-sector acquisitions between 2002 and 2026, with US$99.2 million in disclosed consideration across the 16 deals that have a published price (and a few more that were never disclosed). I verified that count the hard way, deduplicating overlapping records deal by deal, so when I say 19, it is 19. The company itself says about 20, and both numbers are right.

The maple-factory origin story

Because here is the origin story, and I promise it is worth the detour: the very first thing H2O Innovation ever bought was a factory in Victoriaville that built small reverse osmosis systems for maple syrup producers. The young membrane company needed a place to manufacture, the factory had the welders, the automation, the control panel shop, and from one day to the next, a university project could ship water treatment systems. The maple business came along in the deal, and it never left. So when Guillaume counts “soon to be at 20 acquisitions” on the podcast, he is counting from the maple factory; my 19 counts the water-sector deals that followed. And yes, a water company still sells maple equipment, because it kept growing, and nobody walks away from growth out of thematic purity.

That sounds like a lot of buying, so let us put a yardstick on it: US$99.2 million across 16 priced deals is an average of about US$6 million per acquisition. Many single funding rounds in water tech’s venture market are bigger than that. The playbook was never about writing big checks.

What is a sole-source deal, and why does H2O Innovation love them?

A sole-source deal is an acquisition negotiated directly between buyer and seller, with no auction, no bidding war, and no investment bank running a structured process. Of H2O Innovation’s 19 verified acquisitions, exactly one shows a documented competitive process in my records; 14 are evidenced or structurally bilateral, meaning negotiated directly with the seller, and 9 of the 19 used earn-outs.

I will let Guillaume describe the machine himself, because this is the single most quotable minute of the episode.

If you come from tech investing, this is the off-market deal, the pre-empted round, the house bought before the listing went up. And my database says the rhetoric is real: the one banker-run exception was Genesys in 2019, which happens to be one of the largest deals on the list at US$21.7 million. Everything else with evidence was a founder conversation. The earn-out, where part of the price is paid later based on how the business performs, shows up in about half the deals, and that is exactly the structure you would expect when two parties price a company over coffee instead of through an auction. There is even an internal machine for it: an H2O M&A funnel with a senior VP of M&A, separate from Ember’s own funnel.

Is H2O Innovation a roll-up?

Short answer: closer to platform building than to a classic roll-up. A roll-up strategy buys many companies in the same segment to merge them into one bigger entity, often betting that the combined business trades at a higher valuation multiple than the parts. The playbook field in my database reads differently for these 19 deals: 9 add-ons, 6 strategic acquisitions, 2 platform builds, 2 unrecorded.

The distinction matters because pure roll-ups have a rough history, in water as anywhere else. My favorite cautionary tale runs through this exact industry: in 1990, Dick Heckmann bought a struggling little outfit called American Toxxic for US$1.6 million, built it into US Filter through roughly 260 acquisitions, and sold the whole thing to Vivendi for US$6.2 billion in 1999. The asset then lost most of its value, changed hands twice, resurfaced as Evoqua, and in 2023 merged into Xylem at a US$7.5 billion valuation, which works out to more than 4,000 times Heckmann’s starting ticket. Serial acquisition built that company and nearly destroyed it twice. As Reinhard Hübner, who built a $1 billion water revenue company from scratch, put it on the podcast, “the industry is indeed consolidating and it has had consolidation runs before,” and US Filter is the example everyone names. (Reinhard’s SKion Water has since received its own deep dive: 32 quiet deals and one $1.8 billion exit.) H2O Innovation is, at its core, a membrane company.

What separates H2O Innovation from that history is pace and digestion. “We take our time. We take time to integrate,” Guillaume says, and the integration philosophy is deliberately soft: keep the people, keep the channel partners, keep respected brands like Piedmont alive rather than killing them for a tidy logo slide.

How do water companies grow when organic growth is slow?

Water demand compounds faster than water revenue. The editorial line I keep coming back to is that revenue in this sector grows linearly while need grows exponentially, and that structural mismatch is something tariff increases alone cannot close. So a water company that wants to grow fast has exactly two lanes, and H2O Innovation’s answer is to drive in both at once.

And the supply side of this market quietly cooperates. Strategic giants tell small water companies to come back when they are bigger; Karl Michael Millauer, the M&A consultant with 35 water companies on his sell list, says founders hear exactly that, then spend a year or two discovering their real valuation. Which means a disciplined mid-cap with a reputation for closing, for keeping teams, and for paying fairly through earn-outs gets first call on targets the giants never see. The pipeline advantage compounds the same way the revenue does.

What happens when the acquirer gets acquired?

Going private did not stop the machine, and that is the cleanest evidence that the playbook is the asset. Under Ember Infrastructure, H2O Innovation bought NextEra Distributed Water in 2024, Lama Sistemas de Filtrados in September 2025, announced as its 20th deal in 25 years, and in May 2026 announced the acquisition of bestUV, a Dutch UV specialist that founds a whole new disinfection business unit.

In PE language, H2O Innovation is now a platform, the anchor company a fund builds on through further add-ons (a move I dissected in my newsletter on the three PE strategies reshaping water tech, with Ember and H2O Innovation as exhibit one). Ask Guillaume what changed in the deal flow and the answer is, charmingly, not much:

The owner changed, the funnel stayed. Ember bought a company whose product, in a very real sense, is the ability to buy companies well. As Guillaume puts it: “That’s one of the reasons why they were interested in us in the first place.” For the funds watching the water sector, that is the lesson worth stealing: in water, the durable moat was never one technology. It was the relationships that let you buy the next one over coffee.

FAQ: H2O Innovation and the acquisition playbook

Who owns H2O Innovation?

Ember Infrastructure, a New York private equity firm, has owned a majority of H2O Innovation since December 2023. Investissement Québec and CDPQ (Québec’s two big public investment funds) rolled their shares over alongside the management team; together they retain roughly 21%.

How many companies has H2O Innovation acquired?

My Leviathan database verifies 19 water-sector acquisitions between 2002 and 2026, totaling US$99.2 million in disclosed consideration across 16 priced deals. The company counts about 20, which includes the founding purchase of the Victoriaville factory that started the business.

Is H2O Innovation publicly traded?

Not anymore. The company traded in Toronto (latterly as TSX: HEO) until December 2023, when Ember Infrastructure’s take-private at C$4.25 per share closed and the shares were delisted from all exchanges.

What is a sole-source deal?

A sole-source deal is an acquisition negotiated directly between one buyer and one seller, without an auction or a bank-run sale process. Only 1 of H2O Innovation’s 19 verified acquisitions shows a documented competitive process; the rest of the evidenced deals were sourced through direct relationships.

What is due diligence in mergers and acquisitions?

Due diligence is the structured verification a buyer performs before closing: finances, contracts, customers, liabilities, people. Guillaume Clairet’s version is more human: sole-source conversations leave room for the tough conversations about fit and synergies that a tightly run auction process tends to squeeze out.

What are acquisitions in business?

An acquisition is one company purchasing another, either its shares or its assets. Buyers distinguish bolt-ons and tuck-ins (small additions to an existing platform) from strategic or platform acquisitions that open a new market or business line. H2O Innovation’s verified mix: 9 bolt-ons, 6 strategic, 2 platform builds.

Guillaume has lived the startup years, the TSX listing, the take-private, and now the platform era, which is exactly why his read on the next milestone carries weight: the stated ambition is a billion-dollar water company by the end of the decade, and after walking through 19 verified deals, I genuinely cannot tell you whether that number is ambition or just math. Listen to the full conversation with Guillaume Clairet on the (don’t) Waste Water podcast, and tell me in the comments which water mid-cap you think gets bought next.

Let’s get into it!

The Bubble Breakthrough

At the heart of Swirltex’s revolutionary approach lies an elegant yet powerful innovation that harnesses the unique properties of bubbles to transform membrane filtration. The technology introduces carefully controlled air bubbles into the wastewater stream, creating a dynamic spiral flow pattern that fundamentally changes how particles interact with membrane surfaces.

The key breakthrough comes from how these microbubbles influence the fluid dynamics within the membrane system. As wastewater enters the membrane tubes, injected air creates a rotating spiral flow that generates strong centrifugal forces. These forces push heavier contaminants toward the tube walls while allowing cleaner water to flow through the membrane pores. The bubbles also create localized turbulence that continuously scours membrane surfaces, dramatically reducing fouling issues that plague conventional systems.

What truly sets this technology apart is its ability to separate contaminants based on density rather than size alone. Traditional membrane systems rely solely on pore size to filter particles, but Swirltex’s bubble-enhanced approach adds an entirely new dimension to the separation process. The spiral flow pattern can effectively remove oils, suspended solids, and other challenging contaminants that would typically cause rapid membrane fouling.

This innovative mechanism allows the system to operate at lower pressures while maintaining high throughput rates. The reduced operating pressure translates directly to lower energy consumption – typically 30-50% less than conventional membrane systems. Additionally, the continuous scouring action of the bubbles extends membrane life and reduces chemical cleaning requirements, further improving the economics of water treatment and reuse.

The implications of this breakthrough extend far beyond just technical performance. By fundamentally rethinking membrane operation through the strategic use of air bubbles, Swirltex has created a more sustainable and cost-effective approach to water treatment that could help make water reuse viable across a broader range of applications and industries.

Market Pain Points and Solutions

The wastewater treatment industry faces several critical challenges that impact operational efficiency and economic viability. Membrane fouling remains one of the most significant hurdles, causing decreased treatment capacity, increased energy consumption, and frequent cleaning requirements that drive up costs. Traditional membrane systems struggle with high-solids wastewater streams, where suspended particles quickly accumulate on membrane surfaces and clog pore structures.

Operational expenses pose another major pain point, particularly in energy-intensive treatment processes. Standard membrane systems require substantial pressure to force water through fouled membranes, leading to excessive power consumption. Additionally, the chemical cleaning agents needed to restore membrane performance add significant costs while potentially degrading membrane materials over time.

Treatment efficiency suffers greatly when dealing with variable influent qualities. Conventional membrane technologies often fail to adapt to fluctuating waste streams, resulting in inconsistent treatment results and compliance risks. Industrial facilities particularly struggle with this challenge, as production changes can dramatically alter wastewater characteristics.

The bubble-enhanced membrane system addresses these pain points through its innovative approach to solids management. By creating a boundary layer of micro-bubbles at the membrane surface, the technology prevents fouling particles from adhering while simultaneously scouring existing buildup. This self-cleaning mechanism significantly reduces maintenance requirements and extends membrane life.

The system’s enhanced flux rates enable treatment of challenging waste streams with lower operating pressures, resulting in energy savings of up to 50% compared to conventional systems. The technology’s ability to handle varying solids content without performance degradation provides operational stability across diverse applications, from industrial process water to municipal wastewater treatment.

By tackling these fundamental challenges, the technology transforms the economics of water reuse. The reduced maintenance requirements, lower energy consumption, and improved treatment consistency make water recycling more financially viable across a broader range of applications.

Applications and Success Stories

The real-world impact of Swirltex’s innovative membrane technology spans multiple industries, with each implementation showcasing unique solutions to complex wastewater challenges.

A municipal wastewater treatment plant struggling with seasonal algae blooms found similar success. The facility had previously needed to shut down operations during peak bloom periods, creating significant service disruptions. Swirltex’s technology enabled continuous operation throughout algae events while maintaining consistent effluent quality and reducing chemical usage by 35%.

Perhaps the most striking example comes from the food and beverage industry, where a dairy processor was dealing with high-strength wastewater containing fats, oils, and proteins. Traditional membrane systems failed repeatedly due to severe fouling. The Swirltex installation not only handled the challenging waste stream but also achieved 98% water recovery – a 15% improvement over previous systems. The recovered water quality met standards for process reuse, creating a closed-loop system that saved the facility over 100 million liters of fresh water annually.

Mining operations have also benefited from this technology’s unique approach to difficult-to-treat waters. A copper mine implemented Swirltex units to handle tailings water with high suspended solids content. The system’s ability to maintain stable operation despite variable influent quality resulted in a 50% reduction in operational downtime and significant savings in replacement membrane costs.

What makes these success stories particularly noteworthy is how they demonstrate the technology’s versatility across different scales and applications. From small industrial facilities processing 50 cubic meters per day to large municipal plants handling thousands of cubic meters, the core benefits of reduced fouling, lower energy consumption, and improved recovery rates remain consistent. These implementations showcase how innovative membrane technology can effectively clear remote places’ problems while solving environmental issues.

Economic Value Proposition

The implementation of Swirltex technology delivers compelling financial returns through multiple interconnected pathways. At the core of the value proposition lies a dramatic reduction in operational expenses, primarily driven by the system’s unique bubble-enhanced separation process that significantly reduces energy consumption compared to conventional membrane systems.

By leveraging buoyancy to enhance separation, the technology requires up to 50% less energy to achieve the same treatment objectives. This translates directly to lower electricity costs – a major expense item for treatment facilities. The reduced operating pressure also means less wear and tear on equipment, extending membrane life by 2-3 times the industry standard.

Perhaps most significantly, the technology’s enhanced fouling resistance allows facilities to treat challenging wastewater streams that would typically require extensive pre-treatment or frequent cleaning cycles. By maintaining stable operation even with high-solids or oil-laden waters, facilities can minimize chemical cleaning requirements and avoid costly production interruptions.

This operational stability unlocks new opportunities for water reuse and resource recovery. Facilities can now economically treat and recycle wastewater streams that were previously too difficult or expensive to handle. The technology’s ability to handle variable feed quality also reduces the need for buffer tanks and other capital-intensive infrastructure.

Beyond direct cost savings, the technology enables facilities to increase their treatment capacity without major infrastructure investments. The higher flux rates and reduced downtime mean existing membrane systems can process more volume, deferring or eliminating the need for facility expansions. For new installations, the smaller footprint and simplified design reduce upfront capital costs.

When evaluated holistically, facilities implementing Swirltex typically see payback periods of 12-24 months through combined savings in energy, chemicals, maintenance, and avoided capital expenditures. The technology’s reliability and performance consistency also provide intangible benefits through reduced operational complexity and improved compliance certainty.

The technology’s enhanced solids removal capabilities consistently achieve effluent quality that meets or exceeds regulatory requirements across multiple jurisdictions. By effectively removing suspended solids, oils, and other contaminants in a single pass, facilities can maintain reliable compliance with discharge permits while reducing the risk of violations and associated penalties.

From an environmental perspective, the system’s lower energy consumption directly translates to reduced greenhouse gas emissions. The bubble-assisted filtration process requires significantly less pressure to operate compared to conventional membrane systems, resulting in up to 50% lower energy usage. For a typical municipal treatment plant, this can mean hundreds of tons of avoided CO2 emissions annually.

The technology also minimizes chemical usage through improved mechanical separation. As highlighted in how to treat wastewater in a net grid positive way while mimicking your body, reduced chemical dependency not only cuts operating costs but also decreases the environmental impact of treatment processes. The system’s ability to handle varying influent qualities without chemical adjustments further supports facilities’ sustainability goals.

Water reuse applications particularly benefit from the technology’s reliable performance. The high-quality effluent produced enables facilities to confidently implement water recycling programs, reducing their freshwater withdrawal needs and supporting circular economy initiatives. This becomes increasingly critical as regions face growing water scarcity challenges and tightening restrictions on water consumption.

The compact footprint of Swirltex installations also minimizes land use requirements compared to conventional treatment systems.

The Bubble That Started It All

Sometimes the most revolutionary innovations emerge from life’s simplest observations. For Peter Christou, that moment came while watching soap bubbles float through the air, carrying tiny particles in their wake. This casual observation would eventually lead to a breakthrough in membrane technology that’s transforming wastewater treatment.

Christou noticed how bubbles naturally trapped and transported particles through fluid, much more efficiently than traditional filtration methods. This sparked an idea: what if this natural phenomenon could be harnessed to enhance membrane filtration? The concept seemed promising, but translating it into a practical solution would prove challenging.

After years of research and development, Christou and his team discovered that by introducing microbubbles into wastewater streams in a controlled spiral pattern, they could dramatically improve membrane performance. The bubbles created a natural lifting effect, preventing particles from settling and clogging the membrane surface – a persistent problem that had plagued the industry for decades.

The technology works by generating a unique flow pattern that combines centrifugal forces with buoyancy effects. As wastewater spirals through the system, suspended solids are pushed away from membrane surfaces, allowing clean water to pass through more efficiently. This seemingly simple principle has profound implications for treatment economics.

What makes this innovation particularly remarkable is its elegant simplicity. Like nature’s most effective solutions, it harnesses fundamental physical principles rather than relying on complex chemical processes or energy-intensive mechanisms. The result is a more robust and energy-efficient treatment process that can handle challenging waste streams that traditional membranes struggle with.

The journey from soap bubble observation to commercial technology wasn’t straightforward. It required countless iterations, failed experiments, and persistent refinement. But Christou’s unwavering focus on the core principle – letting bubbles do the heavy lifting – ultimately led to a solution that’s elegantly effective in its simplicity.

Breaking Down the Science

At the core of this innovative membrane technology lies a deceptively simple but powerful principle: the strategic use of microbubbles in a controlled spiral flow pattern. When wastewater enters the system, microbubbles are introduced in precise quantities and sizes, typically ranging from 20-100 microns in diameter. These bubbles attach themselves to suspended solids and contaminants through a process known as bubble flotation.

What sets this approach apart is the engineered spiral flow pattern. As the water-bubble mixture moves through specially designed membrane tubes, centrifugal forces create a unique fluid dynamics phenomenon. The lighter bubble-solid combinations naturally migrate toward the center of the spiral, while cleaner water moves to the outer edges. This natural separation significantly reduces membrane fouling – a persistent challenge in conventional filtration systems that typically forces frequent cleaning cycles and increases operational costs.

The physics behind this process leverages both buoyancy and centrifugal forces. When microbubbles attach to particles, they create bubble-particle agglomerates with densities significantly lower than water. The spiral flow pattern then amplifies this density difference, creating a clean separation zone near the membrane surface. This protective boundary layer prevents larger particles from reaching and clogging the membrane pores.

The membrane itself features optimized pore sizes and surface chemistry that complement the bubble-enhanced separation. This synergy allows for higher flux rates – the volume of water that can pass through a given membrane area – while maintaining excellent filtration quality. The system can handle varying contaminant loads without compromising performance, as the bubble generation and spiral flow automatically adjust to changing conditions.

Perhaps most remarkably, this approach requires significantly less energy than conventional membrane systems. The microbubbles, once generated, help maintain the spiral flow pattern with minimal additional energy input. This self-sustaining characteristic, combined with reduced cleaning requirements, translates to lower operational costs and improved sustainability.

Real-World Applications and Success Stories

The transformative impact of Swirltex’s membrane technology becomes evident through several compelling industrial applications. At a major food processing facility in Alberta, the implementation of Swirltex’s system achieved a remarkable 85% reduction in suspended solids while cutting energy consumption by 40% compared to conventional membrane systems. The facility now reuses 75% of its process water, saving over 500,000 gallons annually.

In the oil and gas sector, a prominent operator faced challenges with produced water treatment. After installing Swirltex’s technology, they achieved consistent compliance with discharge requirements while handling variable influent quality. The microbubble-enhanced system maintained stable operation even when total dissolved solids fluctuated between 5,000 and 40,000 mg/L, a feat previously unattainable with standard membranes.

Perhaps most impressive is the technology’s application in municipal wastewater treatment. A mid-sized facility serving 50,000 residents implemented Swirltex as part of their tertiary treatment upgrade. The system’s unique spiral flow pattern prevented membrane fouling so effectively that cleaning frequency decreased by 60%, while permeate quality improved to consistently meet stringent reuse standards.

In the brewing industry, where water quality directly impacts product taste, a craft brewery installed a Swirltex unit to treat process wastewater. The system achieved 99.9% removal of suspended solids and reduced chemical oxygen demand by 95%, enabling direct reuse in non-product applications. This success has sparked interest across the beverage sector, where water conservation increasingly affects the bottom line.

These results demonstrate how Swirltex’s innovative approach to membrane filtration delivers tangible benefits across diverse applications. The technology’s ability to handle challenging waste streams while reducing operational costs has proven particularly valuable in industries where conventional membrane systems struggle.

This natural ingenuity provides the foundation for Blue Foot’s groundbreaking membrane technology.

The most inspiring model comes from mollusks, particularly mussels and oysters. These creatures process gallons of seawater daily through specialized gill structures called ctenidia. These intricate biological filters capture particles as small as 2 microns while maintaining consistent flow rates. The key lies in their unique surface chemistry and structural arrangement that prevents clogging.

Blue Foot’s innovation draws directly from these natural filtration mechanisms. By mimicking the microscopic texture and chemical properties of mollusk gills, their membranes achieve unprecedented selectivity without sacrificing permeability. The technology incorporates nature’s elegant solution to fouling – a dynamic surface that actively repels accumulated particles through slight structural movements, much like a mussel’s periodic shell adjustments.

This biomimetic approach extends beyond just copying nature’s designs. By studying how different marine species adapt their filtration strategies to varying water conditions, Blue Foot developed adaptive membrane properties that automatically optimize performance based on feed water characteristics.

Perhaps most remarkably, this technology harnesses the same principles that allow whale baleen to filter massive volumes of krill-rich water with minimal energy expenditure. The membrane’s internal channels are arranged in patterns that maximize flow efficiency while maintaining selective filtration, much like the finely-tuned hydrodynamics of baleen plates.

As explored in how biomimicry leverages the best of 3.8 million years of research and development, this nature-inspired innovation represents a fundamental shift in membrane design philosophy. By working with, rather than against, biological principles, Blue Foot has created a technology that promises to transform industrial water treatment.

Breaking the Fouling Barrier

Membrane fouling has long been the Achilles’ heel of industrial water treatment, causing reduced flow rates, increased energy consumption, and frequent cleaning cycles. The biomimetic structure of Blue Foot membranes represents a paradigm shift in addressing this persistent challenge.

The membrane’s unique architecture incorporates microscopic surface patterns that mimic the natural defense mechanisms found in marine organisms. These patterns create localized turbulent flows at the membrane surface, preventing the accumulation of foulants while maintaining laminar flow through the membrane pores. This self-cleaning mechanism significantly reduces the formation of biofilms and mineral scaling.

Beyond surface modifications, the membrane’s internal structure features a gradient of pore sizes that distributes hydraulic resistance more evenly. This distribution prevents the concentrated accumulation of particles at any single point, much like how kidney tissues process waste materials through progressively finer filtration stages.
