The Onsite Wastewater Program is responsible for all permitting and inspecting activities that require a septic tank system for wastewater disposal while offering technical assistance to those designing septic and wastewater systems.
What is a septic system?
A septic system is a subsurface wastewater system consisting of a settling tank and a subsurface disposal field. Septic systems are used when sewage treatment plants are not accessible. They safely treat and dispose of wastewater produced in the bathroom, kitchen and laundry. Wastewater may contain disease-causing germs and pollutants that must be treated to protect human health and the environment.
