The Clean Water State Revolving Fund helps Oregon communities protect water quality by offering low-interest loans for a variety of clean water projects like wastewater treatment, stormwater management, habitat restoration, land acquisition and more! As loans are repaid, the funds are reused to support new projects across the state.

Other types of Loan support
In addition to directly funding projects, Clean Water State Revolving Fund dollars can go to communities to support loan programs within those communities.
The Local Community Loan encourages public agencies, often rural counties, soil and water conservation districts or irrigation districts, to use revolving fund financing to establish their own local loan program to address local water quality issue(s) within their jurisdiction.
The Community Development Financial Institution Loan allows Clean Water State Revolving Fun to offer financing to qualified institutions who will make sub-loans to individuals to either
- repair or replace failing on-site septic systems, or
- replace failing on-site septic systems with connections to an available sewer.
If you're interested in these loans, contact DEQ staff or submit a Loan Information Request Form. Staff contacts are listed on the Clean Water State Revolving Fund contacts home page.
