The Onsite Program is designed to provide wastewater treatment and dispersal for homes that are not served by a community or centralized sewer system. Drainfields must be properly designed and installed for two reasons:

  • To protect the groundwater aquifer because contaminated groundwater can affect drinking water supplies and pollute rivers, lakes and streams
  • To protect public health because improper disposal of sewage causes many diseases in humans.

The purpose of the Onsite Program is to provide the homeowner with a sewage treatment and dispersal system that is as trouble free as possible and that protects residents from health problems relating to exposure to surfacing sewage and prevent contamination of the water supply.

 The first step to approval for an onsite wastewater treatment system is the site evaluation.
