About WalCoMet
The Walworth County Metropolitan Sewerage District (WalCoMet) is a water reclamation facility that was created by an order dated December 26, 1974, by the Wisconsin Department of Natural Resources, pursuant to Wisconsin Statutes Sections 200.01 to 200.16, to include all territory within the corporate limits of Elkhorn and the area served by the Delavan Lake Sanitary District (DLSD). In subsequent actions, the following areas were added to form the present service area of WalCoMet: Walworth County Institutions, the City of Delavan, the Village of Williams Bay, the Town of Walworth Utility District No. 1 (Inspiration Ministries), Geneva National Sanitary District, the Village of Darien, the Town of Darien Utility District No. 1 (Pioneer Estates Mobile Home Park), Lake Como Sanitary District and Mallard Ridge Landfill.
The total area serviced lies within the corporate boundaries of these 11 entities and comprises approximately 16 square miles and have a current population of over 28,000 residents. The ultimate drainage area that can contribute to the system encompasses about 70 square miles. Wastewater discharged within each entity enters their collection system where it is either pumped or flows by gravity to the 10 lift stations, 31 miles of force main, and 7 miles of gravity sewers owned and maintained by WalCoMet. Flow from each entity is measured and sampled at lift stations. Each lift station must be maintained for continuous service.
