The Manitowoc Public Utilities Cross Connection Control Program is designed to prevent backflow or backsiphonage of contaminated water into the drinking water supply. The MPU program has been around for many years, but has recently been updated in response to changes in State regulations in an effort to better protect potable (drinking) water systems from potential contamination. This program is run in accordance with the Wisconsin Department of Natural Resources (WDNR) and NR810.15 of the Wisconsin Administrative Code. MPU is required to report to the WDNR annually on the status of testing and inspecting cross connections at the businesses and homes that we serve.
