Our septage procedures are designed to comply with all applicable District, State and Federal regulations. Septage is regulated by our Rules and Regulations. The Tri-City Water Resource Recovery Facility (TCWRRF) is the only designated receiving facility in WES. Haulers that discharge septage at the TCWRRF are required to have a valid Septic Tank Waste Discharge Permit, which is issued for a three-year period.
Permit Application Process
To apply for a WES Septic Tank Waste Discharge Permit, septage haulers must complete and submit a completed Application for Permit form, current copy of DEQ license for sewage disposal, a $10,000 Surety Bond or Bond Continuation Certificate, a current copy of the DEQ Pumping Truck Inspection Report and three-year permit* fee. The application review process takes approximately 3–5 days after which the WES staff will then issue or deny a septage discharge permit.
Septic Tank Waste Discharge Permit application can be downloaded online. For additional information, contact WES Industrial Pretreatment Program at 503-557-2834.
* WES Septic Tank Waste Discharge Permit is a three (3) year permit, however, surety bonds, DEQ license, and DEQ Truck Inspection are issued annually. An updated copy of these items must be submitted to WES Septage Program annually.
