What makes a real water investor
Most "water investors" aren't. The single most common pattern in water capital is the one-and-done: a fund writes a single water cheque, never returns, and quietly exits the category, yet still shows up on every "investors in water" list. That noise is exactly what this ranking is built to cut through.
The Water Commitment Score rewards behaviour, not branding: repeat water bets, recent activity, leading and re-upping, and genuine water focus. It is why a small, dedicated fund like Burnt Island or Echo River outranks a giant generalist with one water deal, and why a fund that was active years ago but has gone quiet slips down the ranking as its staying power decays.
