Why do I need a sanitary permit?
A sanitary permit is necessary to ensure that a proposed Private Onsite Wastewater Treatment System (POWTS) installation will meet the minimum standards specified in the Wisconsin Administrative Code that governs this issue. These standards specify a POWTS separation requirements to seasonal water table, wells, lot lines, structures, water lines and mains, etc. It also identifies treatment methods and products that are acceptable for use in Wisconsin POWTS and the manner in which they should be installed.
