An as-built is a drawing of your septic system in relation to your house and property boundaries. Your septic system Designer completes the as-built after the septic system is installed. Public Health – Seattle & King County keeps these as-built drawings on file as public information.

You can request Public Health to search their records for your septic system. It is highly recommended to obtain a copy of your as-built for landscaping projects. See Landscaping tips with a septic system for more information.

NOTE: Not all records are complete and older septic systems may not have as-builts.
