Grant And Loan Resources


Funding programs of the Combined Funding Cycle

  • Centennial Grants

    • This program is funded by state dollars, provided primarily via the State Building Construction Account. The Centennial program provides grants for water quality infrastructure and nonpoint source pollution projects to improve and protect water quality. Eligible infrastructure projects are limited to wastewater treatment construction projects for financially distressed communities. Eligible nonpoint projects include stream restoration and buffers, on-site septic repair and replacement, education and outreach, and other eligible nonpoint activities.

  • Clean Water Act Section 319 Federal Grants

    • The federal Environmental Protection Agency (EPA) provides Section 319 grant funds to Washington State with the state required to provide 40 percent match in funding. The Section 319 program provides grants to eligible nonpoint source pollution control projects similar to the state Centennial program.

  • Clean Water State Revolving Fund Loans

    • Provided for by the federal Clean Water Act (CWA), the Clean Water State Revolving Fund (CWSRF) program is funded via an annual EPA capitalization grant, state matching funds, and principal and interest repayments on past CWSRF loans. This program provides low interest and forgivable principal loan funding for wastewater treatment construction projects, eligible nonpoint source pollution control projects, and eligible Green projects.

  • Stormwater Grants

    • As state and federal funds are appropriated through legislative budget process, Ecology offers financial assistance to local communities to implement projects that prevent or mitigate water pollution from stormwater though four state-funded grant programs. Eligible projects include the design and construction of stormwater facilities that address water from existing hard surfaces, green stormwater retrofits, education and outreach programs, stormwater research, and activities that support stormwater permit implementation.
