Ecology has funded on-site sewage local loan programs since 1988 through the Washington Water Pollution Control State Revolving Fund (SRF). Beginning in 2007, after changes in the Centennial Clean Water Act (Centennial) Rule (713-95A WAC), Ecology has awarded Centennial grants to local governments along with SRF loans. The Centennial grant funds may be used to cover the costs of running the programs, loan loss reserves, and hardship grants to low income homeowners.
Most of the OSS programs in the state are on the west side of the mountains, with properties affecting Puget Sound being targeted.

At the time the program was started, the value of homes and properties throughout Puget Sound had been increasing. However, even at that time, and more so in the years since, finding money - particularly for low-income or long-time homeowners and small businesses - has been a primary obstacle to fixing or replacing aging or failing onsite septic systems.
Ecology administered the loan (Clean Water State Revolving Fund) and grant (Centennial Clean Water) funds awarded to local governments. The local governments, in turn, provided grants and low-interest loans to homeowners and small businesses with failing OSS. The map below shows the locations of repairs made using these set-aside funds.
