The Water Treatment Plant, located at 72 Park Avenue, produces all of the potable water for Sheboygan, Sheboygan Falls and Kohler. On average, more than 15 million gallons of water are produced per day. Increased consumption in summer requires production of up to 27 million gallons of water.

The municipal water distribution network throughout the city is maintained by the Sheboygan Water Utility. This consists of more than 205 miles of water mains, 3000 valves, 2000 fire hydrants, three booster stations, and six tanks or reservoirs. New water main design and installation is performed by the Utility in accordance with local ordinances. In addition, the Utility repairs broken water mains around the clock.

The Service Department of the Utility handles all aspects related to water meters for both residential and industrial customers: reading, installation, testing and repair. The accuracy of the meters is important to ensure customers are charged accurately for their usage.

In addition to water charges for over 20,000 customers, the Utility also performs the billing, account maintenance and collections for sanitary sewer usage and garbage collections.
