Properly designed and installed sewage treatment systems (STS) along with periodic maintenance ensure sewage is sufficiently treated prior to disposal. Protecting the public and the environment from disease-causing organisms and toxic pollutants is equally as important as having a system that drains freely.
For this reason, sanitarians from the Environmental Health Division assess site and soil information to design systems that are specific to the location. The slope, surface features, isolation distances, soil morphology,and amount and type of waste flows are all incorporated into the design calculations.

Once a sewage treatment system is installed and approved, routine maintenance is critical to ensure a safe, viable, long-lasting system.

A permit is required from the Health Department to install, repair, or replace a STS that serves a dwelling or a building that generates less than 1000 gallons of waste per day. Installers, Haulers, and Service Providers are registered through the Health Department and must be covered by general liability insurance and a statewide bond.
