1. Who needs septic as-built information?

State law requires that homeowners inspect and maintain their septic system to ensure it is functioning properly. An as-built drawing shows the location of your drain field, which is also useful for:

• Property owners doing landscaping or building
• Real estate professionals preparing for a purchase or sale
• Septic professionals doing maintenance or repair

2. What information is in a record?

Information on each property record includes:

• Year built
• Legal description
• Ownership and septic system status
• Type and location of the drain field installed on the property, if there is one

3. Where does the septic information come from?

In general, the only information included is the as-built drawing, even though additional information on the property’s septic system may be on file at the Snohomish Health District offices.

The "Property Site Information" and "Property Owner Information" sections are from the Snohomish County Assessor’s Office and are updated on a routine basis. The "OnlineRME" and "Comments" sections are entered by the Snohomish Health District Water and Wastewater program. Attached scans are from the district’s files.
