About this program
The Environmental Protection Agency is funding planning, design, construction, and operation of drinking water system resilience projects under CFDA 66.448, with the most recent grant award issued on October 1, 2025. The program has distributed $17.3 million in federal funding across 11 awards since November 2024, with activity accelerating from 2 awards in 2024 to 9 awards in 2025.
The program supports concrete infrastructure and planning activities that increase drinking water system resilience to natural hazards in underserved communities and systems serving populations under 10,000. Eligible activities include water conservation and efficiency improvements, modification or relocation of infrastructure at risk from flooding and other natural hazards, desalination facility design and construction, watershed management and source water protection, renewable energy integration in water conveyance and treatment, and resilience enhancement measures. Recent awards fund service line replacements (copper and PVC piping), emergency generator installation at water treatment facilities, integrated water resources management planning, cistern sensor networks for drought monitoring, water main interconnections, and storage tank aeration systems.
Funding is distributed across seven EPA regional offices. EPA Region 9 and Region 10 dominate by federal dollars obligated, together accounting for $12.7 million of the total $17.3 million. The remaining regions contribute in smaller increments, with Region 3 at $2.9 million and the long tail at under $600 thousand per region. All 11 awards issued to date are Project Grants, with no Cooperative Agreements awarded.
Award magnitudes range from $240 thousand to $4.7 million, with a combined non-federal match of $400 thousand across the portfolio. Representative recent awards include the City of Fresno's $3.7 million project to replace 891 deteriorated polyethylene service lines with copper piping, the U.S. Virgin Islands Department of Planning and Natural Resources' $400 thousand effort to deploy wireless sensor networks and develop integrated water supply models for drought resilience on St. Croix, and the City of Saint Paul, Alaska's $4.6 million infrastructure upgrade targeting power reliability and water quality monitoring.
The most recent posted opportunity (EPA-OW-OGWDW-23-01) closed on November 6, 2023. No current open solicitation is listed in the source.
