Where does septic information on the as-built site come from?

In general, the only information included is the as-built drawing, which is the final drawing of what your system looks like after installation. Additional information on the property’s septic system may be on file at the Snohomish County Health Department  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 County Health Department Land Use program. Attached scans are from the district’s files.
