The Water Utility owns and operates 5 drilled wells, 3 aboveground storage tanks, 1-1.25 million gallons underground treatment reservoir, and more than 66 miles of distribution water mains ranging from 4-inch to 16-inch diameter size.  The utility supplies approximately 1.5 million gallons of potable drinking water to its customers on an average day.  The water supply is served to residential, multi-family, commercial, industrial, and public authority customers.  The water supply distribution system also provides for public and private fire protection systems located throughout the service area.

The water utility treats its' native groundwater water supplies with the addition of fluoride to promote dental health; caustic soda to adjust native pH and protect against corrosion; polyphosphates to sequester iron and manganese and protect against leaching of copper and lead; and chlorine for disinfection.  All chemical additions are monitored and controlled to meet the US Environmental Protection Agency (EPA) and the Wisconsin Department of Natural Resources (WDNR) regulatory requirements.

  • Operate and maintain wells, pumps and treatment facilities
  • Operate and maintain distribution mains, towers, and services
