Septic and Onsite Wastewater Program

We regulate the installation, repair, and maintenance of septic systems on homes and businesses not served by community sewer systems. Septic and onsite wastewater treatment systems must be designed, installed, and maintained to protect:

  • the groundwater aquifer and surface waters from pathogen and nitrogen contamination
  • public health by properly treating and disposing of disease-causing human waste
