Grants and contracts for water supply, treatment, reuse and resilience. The active funders are the World Bank and regional development banks, EU LIFE and Horizon, the US EPA, and water utilities procuring through the public-tender feeds. Listed below are the open water grant calls in that landscape, taken from each funder's own notice and re-checked on every refresh.
Water and ocean funding sits mostly with development finance and national infrastructure budgets rather than with innovation programmes. The recurring sources are the World Bank and the regional development banks, the Green Climate Fund, EU LIFE and Horizon, and national water and environment agencies. Awards tend to be tied to a specific catchment, coastline or utility, so geographic eligibility is usually the first thing to check rather than the last.
This page lists open water grants currently tracked by Raise Lens — 629 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is water work rather than anything whose description happens to mention it.
The funders publishing water grants here include Imagine H2O, Echo River Capital, Keystone Foundation, among 2 others. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between funders than between individual calls.
Geographic coverage on this page spans SE-ASIA, ASIA, NORTH-AMERICA, GLOBAL, GLOBAL-SOUTH. Eligibility is usually tied to where the work happens or where the applying organisation is registered, and the two are not always the same — worth checking before investing time in an application.
