On-site sewage system projects
Our on-site sewage system funding allows local partners to provide grants and loans for repairing and replacing private systems, such as fixing a failed septic system. Failing systems threaten water quality and public health.
On-site sewage systems — such as septic systems — are an excellent way to treat residential or small business wastewater in areas where a sewer system is not available. Failing on-site sewage systems (OSS) threaten Washington’s drinking water supply, which primarily comes from groundwater. They also negatively affect Washington’s multi-million dollar shellfish industry, treaty rights, recreational opportunities, and can create public health hazards.
A failing OSS can be expensive to repair or replace. In Washington, a new conventional system can cost upwards of $25,000; the cost for an alternative system can be a lot more. Property owners can find themselves facing a bill they may not be able to afford.
Local programs are here to help
We provide funds to local partners to set up programs to help homeowners repair or replace failing OSS. These programs help property owners secure financing for fixing a failing OSS who may otherwise be unable to qualify for traditional financing.
The Water Quality Combined Funding program provides funding for this work. Funding comes from the Clean Water State Revolving Fund (CWSRF) and the Centennial Clean Water Fund. In addition to funding OSS repair and replacement, this program can also support rebate programs for ongoing maintenance of septic systems, homeowner workshops, and development of local management plans.
The OSS Regional Loan Program (RLP) provides financing for the repair and replacement of OSS through Craft3, a non-profit third-party lender. The RLP is a partnership between Ecology, Department of Health, local counties and health departments, and Craft3.
Craft3 offers affordable Clean Water Loans to help property owners repair or replace their failing septic systems and — if approved by the county — to connect to municipal sewer systems.
Loan features include:
- Financing the full cost of designing, permitting, installing, and maintaining your septic system
- Competitive interest rates and no up-front costs
- Highly inclusive for a range of incomes and property types (including commercial and non-owner occupied)
- Deferred payment options may be available for homeowners with lower income
- A $2,000 reserve to support the system’s ongoing health

While the OSS Regional Loan Program is an option for homeowners across the state, Ecology is supporting a handful of other programs that can help homeowners in certain areas.
The Clallam Conservation District provides funds to low-income homeowners for OSS repair and replacements in high-priority areas throughout the county.
