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?
Funding for drinking water, wastewater, sewer, and stormwater systems — water main and treatment-plant upgrades, sewer and stormwater improvements, and water-system planning — for municipal water and sewer utilities, towns, and special districts. Typical eligible costs include construction and rehabilitation, engineering and design, planning, equipment, and the local share of a capital project for towns, cities, counties, special districts, and utility authorities.
