The Water Funder Initiative (WFI) is a left-of-center environmental advocacy group and a project of the Windward Fund.

The Water Funder Initiative promotes “water sustainability” in conjunction with the center-left Energy, Hewlett, Packard, Walton, S.D. Bechtel, Mitchell, and Rockefeller Foundations. Among other things, the Initiative seeks to create a “water fee” in key states such as Texas, California, and Colorado to pay for “affordable basic [water] supplies for disadvantaged communities”; “reform municipal and green bond rules” to encourage more public financing of environmentalist projects; and support politicians who want to alter water rate structures in order to “incentivize conservation.” ^[1]
