Septic System Operational Certificate

Thurston County regulations require an Operational Certificate, issued by Thurston County Health Department, for certain types of septic (on-site sewage) systems and systems within designated areas of the County. The goal of the Operational Certificate is to assure that septic systems are properly operated and maintained. Properly monitored and maintained systems have longer operating lives and less impact on our water resources.

There are two programs for renewal of the Operational Certificate. Depending on where your septic system is in Thurston County and what type of septic system is installed, determines the guidelines for inspecting and renewing your Certificate.
