Water quality grants and loans

We have information and resources for water quality-related funding opportunities, as well as tools needed to manage projects funded by our Water Quality funding programs.

Funding opportunities vary by funding source, funding category, and project type. With a single application process and funding list, we can create funding packages that meet the financial needs of project applicants.
 

Water Quality Combined Funding Program

The annual single-application process to apply for funding from multiple sources all at once, for eligible projects that benefit water quality. For the funding program guidelines, click the heading link above.

The current (State Fiscal Year 2019) Draft List of applicants projected for funding is now available.
 

Funding sources of the Water Quality Combined Funding Program

Clean Water Act Section 319 Federal grants

The U.S. Environmental Protection Agency (EPA) provides grants to Washington under Section 319 of the federal Clean Water Act. The state is required to provide a 40 percent match in funding. The Section 319 grant program offers funding to eligible nonpoint source pollution control projects, similar to the state Centennial Clean Water Program.

Centennial Clean Water Program grants

To improve and protect water quality, the state Centennial Clean Water Program provides grants for water quality infrastructure and nonpoint source pollution projects. 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 State Revolving Fund loans

Provided by the federal Clean Water Act (CWA), the Clean Water State Revolving Fund (CWSRF) program is funded through an annual EPA capitalization grant, state matching funds, and principal and interest repayments on past program loans. The CWSRF 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 Financial Assistance Program grants

The Stormwater Financial Assistance Program (SFAP) is designed to fund stormwater projects and activities that have been proven effective at reducing impacts from existing infrastructure and development and enhance existing stormwater programs. Stormwater facility projects and a limited set of stormwater activities project types are eligible for SFAP funding. 
 

On-site Sewage Systems Program

This program provides funds to local governments to set up low-interest loan programs to repair or replace failing on-site sewage systems. Property owners unable to qualify for conventional bank loans and marine waterfront property owners can use the program get loans to fix or replace their systems where failures might directly affect Puget Sound. Both the Clean Water State Revolving Fund and the Centennial Clean Water Program provide funding for this program:
  • Clean Water State Revolving Fund (CWSRF) loans can be used by counties and cities to loan money to qualified land owners to repair or replace their failing on-site sewage systems.
  • Centennial Clean Water Program grant funds can help defray some of the operating costs and lending risks for these programs. Local governments can grant funds to cover operating costs for the program, provide small grants to property owners, and establish a loan-loss reserve account to cover their obligations should a property owner default on a loan.
