Water Innovation Fund
Water Innovation Fund is an early-stage investor in water technology. In the (don't) Waste Water Leviathan directory it appears through a single holding, FieldFactors, the Dutch company behind the Bluebloqs system for capturing, cleaning and reusing urban rainwater. As of 2026 that is its one water-relevant company, a one-off rather than a dedicated water portfolio.

The take
Water Innovation Fund is one of the quieter names in water tech, a backer that turns up in funding announcements rather than on a conference stage. In the directory I keep for (don't) Waste Water it appears through a single company, FieldFactors, the Delft team turning paved cities into sponges: catching storm water where it falls, filtering it through nature-based biofiltration, and banking it underground for reuse instead of letting it run to the drain.
Water Innovation Fund travels light on the public record. It backs water-technology companies at the seed stage and invests alongside dedicated water specialists, but it publishes little about a wider thesis, a team, or a fund size, so this profile sticks to what is verifiable rather than what could be inferred. The name itself is generic: several public grant programmes use the words 'water innovation fund', which makes it easy to confuse with schemes that hand out non-dilutive money rather than take equity.
Water Innovation Fund is, for a newcomer mapping who actually writes cheques into water, a one-off data point, not a destination. Its single seed position in FieldFactors plants it firmly in the nature-based, urban-water-reuse corner of the market, next to the climate-and-water specialists active there. If more of its activity becomes public the picture will fill in; for now it is one honest line in the ledger, worth knowing precisely because the water field is small enough that even a single conviction bet counts.

Frequently asked
- What does Water Innovation Fund invest in?
- Water Innovation Fund backs water-technology companies at an early stage. In the (don't) Waste Water Leviathan directory it holds one water-relevant company, FieldFactors, which builds nature-based systems that capture, clean and reuse urban rainwater. Its visible activity sits in the urban water-reuse corner of climate technology.
- Is Water Innovation Fund a dedicated water fund?
- On the public record there is little to confirm a water-only mandate. Water Innovation Fund appears in the directory through a single seed-stage water investment, FieldFactors, so (don't) Waste Water treats it as a one-off water backer rather than a specialist fund built solely around water.
- Is Water Innovation Fund the same as the UK water innovation grant programme?
- No. Several public bodies run grant schemes with 'water innovation' in the name, such as the UK water regulator's Innovation Fund, which awards non-dilutive money to utilities. The Water Innovation Fund in this directory is an equity backer that took a stake in the startup FieldFactors, not a grant scheme.
- How many water deals has Water Innovation Fund done?
- In the (don't) Waste Water Leviathan database, Water Innovation Fund has one water-relevant company, FieldFactors, across a single seed-stage deal recorded in 2025. That makes it a one-off entry rather than a repeat water investor in the activity tracked so far.
