How to Properly Decommission a Septic Tank

Decommissioning a septic tank in King County follows a specific process:

1. Pump and Clean the Tank – Before anything else, the tank must be completely emptied. This is where we come in.
2. Disconnect and Abandon – Once pumped, the tank is disconnected from the wastewater system.
3. Filling or Removal – Depending on county requirements and property needs, the tank is either removed or filled with inert material (such as sand or gravel).
4. Report Submission – To complete the process, a Report of Wastewater Tank Abandonment must be filed. We provide this document after pumping the tank.
