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.
