The Zoning Department administers the Winnebago County Sanitary Ordinance and Chapter SPS 383 of the Wisconsin Administrative Code, which regulate the installation and maintenance of Private Onsite Wastewater Treatment Systems (POWTS), better known as "septic systems." Both the Winnebago County Sanitary Ordinance and SPS 383 require that all septic systems, regardless of when they were installed, must be inspected/serviced a minimum of once every three (3) years.
Maintenance involves the visual inspection of the system by a licensed plumber, pumper, or inspector, and includes pumping of the septic tank(s) and pump chamber (for dosing, in-ground, at-grade, and mound systems) by a licensed pumping service. Your system may include an effluent filter on the outlet of the septic tank or may have a filter in the pump chamber. If so, that filter must be cleaned.
