Clean Water State Revolving Fund (CWSRF) Program

The Clean Water State Revolving Fund (CWSRF) provides low‑interest loans, principal forgiveness, and grant options to public agencies, tribal governments, nonprofits, and other eligible entities for water‑quality infrastructure projects across California. Funding can cover construction of wastewater treatment plants, sewer systems, stormwater facilities, water reclamation, and non‑point source pollution controls. Financing terms include interest rates at half the most recent General Obligation bond rate, terms up to 30 years (or the useful life of the project), and repayment beginning one year after construction. Small disadvantaged communities may qualify for up to 100 % grant forgiveness. The program is open continuously, with a typical performance period of three years. Applicants submit an online application and must meet eligibility criteria such as serving populations under 20,000 and meeting income thresholds. • Eligible applicants: cities, towns, districts, state agencies, tribal governments, 501(c)(3) nonprofits, and approved management agencies. • Eligible projects: wastewater treatment, sewer interceptors, water reclamation, stormwater treatment, landfill leachate treatment, and non‑point source pollution mitigation. • Financing: loans (reimbursement method), possible principal forgiveness or grants (up to 100 % for qualifying communities). • No maximum funding limit; partial funding may be allocated annually. • Period of performance: 3 years; award announcements are continuous.
