rural SERVICE areas
While we directly serve our owner communities, the municipalities and utility/sanitary districts with sewer infrastructure and collection services, we also serve rural homes and businesses in the region via septic waste disposal services for septage haulers and RVs. Septage haulers are required to have a permit before using the service and are subject to disposal fees, according to the type of waste.
Service Area expansion
Developers seeking to expand the District’s service area to new locations beyond existing boundaries can apply for annexations, sanitary sewer extensions or new developments / redevelopments. There is a formal application process to follow according to Wisconsin state statute. Review materials in the developers section of our website.
