The Snohomish Health District offers an online database of septic system records for properties in Snohomish County. These electronic records contain septic as-built drawings, system type, and in some cases notes on septic maintenance and other permit activity. “As-built” refers to the drawing on file that shows where a drain field (septic system) was installed on a particular piece of property.
The Snohomish Health District was the first local health jurisdiction in Washington to develop an electronic database for as-built records. Beginning in 1997, we began scanning as-built and permit records into the system. The system became available online to the public in 2006.
