Delavan Lake Sanitary District and Walcomet (Walworth County Metropolitan Sewerage District)

The original plan for sewer service provided that DLSD would construct a sewer collection system around Delavan Lake and would own and operate a wastewater treatment facility. However, a number of other communities in the area were experiencing wastewater problems with their respective treatment facilities. A study was conducted indicating that the most cost-effective solution to the wastewater problems of not only DLSD, but also a number of the surrounding communities, was to create a regional wastewater treatment facility. Accordingly, the Walworth County Metropolitan Sewerage District was created in the mid-1970s by order of the Wisconsin Department of Natural Resources. It owns and operates the regional treatment facility. DLSD was one of the original customers of WALCOMET and continues in this capacity.
