Sanitary Sewer

The City of Franklin does not discriminate on the basis of race, color, national origin, sex, age, or disability in its programs or activities. 

The Sanitary Sewer Division accounts for the activities of the sanitary sewer operations of the City.  The City is part of the Milwaukee Metropolitan Sewerage District (MMSD), which provides interceptor sewers and treatment of the sanitary sewage generated in the City.  Sewer activities handled by City personnel include maintenance and cleaning of collection sewers and monitoring of the sanitary sewer system located within the City.

Sewer bills are based on water usage where water is provided from the Franklin Water Utility and are a flat charge for all single-family and two-family customers.
