Septic and Onsite Wastewater Program

Septic and Onsite Wastewater program has moved

Effective Jan. 4, 2016, our program that reviews septic and onsite wastewater systems moved to the Clackamas County Department of Transportation & Development. You shouldn't notice much of a difference, as they are still available on the second floor of the county Development Services building. Phone numbers and email remain the same.

The onsite wastewater treatment systems program is designed to regulate the installation, repair, and maintenance of septic systems on homes and businesses not served by community sewer systems. Onsite wastewater treatment systems must be designed, installed, and maintained for the following reasons:

  1. To protect the groundwater aquifer and surface waters from pathogen and nitrogen contamination.
  2. To protect the health of the populace by properly treating and disposing of disease causing human waste.
