Water & Wastewater grant FAQ

Who funds water & wastewater programs?

Water & Wastewater programs are funded by the same infrastructure ecosystem as the rest of the field: USDOT and the EPA at the federal level, the state DOTs and state water and sewer programs that administer and re-grant federal transportation and water-infrastructure funds, the Bipartisan Infrastructure Law, and state capital programs. Some funders run dedicated lines; many fund this work through broader public works and infrastructure programs.

What can water & wastewater grants pay for?
