City of Oconomowoc and Environs


Sanitary sewer service area plans for the City of Oconomowoc and Environs that identify the outer boundary of the area within which sanitary sewers may be extended. The plans also identify the extent of environmentally sensitive lands within each sewer service area. A map identifying the location and extent of the State-approved sanitary sewer areas may be found here on the SEWRPC Regional Map Server

Upon approval of the SSA Plans, sewer extensions must be in conformance with the delineated 20-year growth boundary. As the designated water quality management planning agency for the seven-county southeastern Wisconsin Region under the Federal Clean Water Act, SEWRPC is responsible for working with local governments and sewerage plants and the Wisconsin Department of Natural Resources to ensure that the federal and state laws are fulfilled.
