Septic Application Status

You can check your current application status online.

Designing and building a septic system on your property can be a lengthy process. 

State and local rules and regulations require that you first hire a licensed professional who will evaluate your site, design a system, and complete the permit application process with our office. 

For more information on the application and permitting process, take a look at our permit process steps page.

The Snohomish Health Department reviews septic system designs for single-family homes and small businesses (systems less than 3,500 gallons per day). The Washington Department of Health enforces regulations for larger sewage systems in Snohomish County.
