Subsurface Sewage Treatment System (SSTS) Program
Most homes and businesses in municipalities discharge their sewage to publicly owned sewage treatment plants. In rural areas, sewage is treated "onsite" utilizing septic tanks and soil treatment areas. These systems are called Subsurface Sewage Treatment Systems (SSTS). In either case, it is extremely important that sewage be treated properly to insure safe drinking water and safe water recreation, and so that the public is not exposed to health risks from sewage.

Winona County Planning Department through the Zoning Ordinance and authority from the Minnesota Pollution Control Agency regulates the design, permitting, installations, and inspections of Subsurface Sewage Treatment Systems (SSTS).
