As-Built Records

The Snohomish Health District offers an online database of septic system records for properties in Snohomish County, which can show you what your existing system looks like and what type it is. 

These electronic records contain septic as-built drawings, system types, and may include notes on septic maintenance or other permit activity. “As-built” refers to the drawing on file that shows where septic system components were installed on a particular piece of property.
