About this program
The Environmental Protection Agency is distributing capitalization grants through the Clean Water State Revolving Fund (CFDA 66.458) to state environmental agencies and territorial governments to finance wastewater treatment infrastructure projects and water quality management activities, with most recent awards closing in May 2026. The program capitalizes state-administered revolving funds that issue low-interest loans to municipalities, utilities, and other subrecipients for planning, design, and construction of eligible water quality improvement and protection projects. Recent awards reflect an expanding emphasis on emerging contaminants—manufactured and naturally occurring substances including pharmaceuticals, industrial chemicals, pesticides, and microplastics—as well as climate resilience initiatives targeting wastewater treatment infrastructure damaged by hurricanes and wildfires.
The program is highly active, with 1,828 awards totaling $46.44 billion in federal obligations and $52.34 billion combined federal and non-federal dollars obligated since program inception in 1994. Award cadence has grown steadily: 155 awards in 2025 and 166 in 2024, compared to 122 in 2022. Funding is dominated by EPA headquarters ($26.9 billion across 1,042 awards, or 58 percent of federal dollars), with significant concentration in EPA Region 4 ($3.91 billion, 134 awards), Region 5 ($3.78 billion, 86 awards), and Region 2 ($3.45 billion, 54 awards). The portfolio is predominantly Formula Grants (85 percent, 1,549 awards) with a smaller complement of Project Grants (15 percent, 279 awards).
Recent awards range from $29 thousand (Karuk Indian Tribe emerging-contaminants assessment, August 2025) to $166.4 million (Ohio EPA, January 2026). Representative capitalization grants include $81.86 million to Kansas, $42.94 million to Tennessee for IIJA-funded wastewater infrastructure, $107.18 million to an unnamed recipient for general CWSRF financing, and multiple emerging-contaminants-focused awards in the $1–$10 million range to South Carolina, Ohio, Minnesota, Oregon, and Connecticut. Recent awards also surface new priority areas: South Carolina received $9.4 million for decentralized wastewater systems resilience post-hurricanes, and Hawaii received $22.4 million for wastewater treatment works recovery from hurricanes and wildfires.
No open grant opportunities for new applicants are present in the source. Applicants are state environmental agencies, state revolving fund administrators, and tribal entities. Award approval averages 45 days. Pre-application coordination with the appropriate EPA Regional Office is required, and states must prepare and provide for public comment an intended use plan identifying eligible projects.
