Cross Connection Program

Overview

In accordance with the Safe Drinking Water Act of 1974, the Wisconsin Department of Natural Resources (WDNR), under NR 81.15, requires municipal water suppliers to develop and implement a comprehensive cross-connection control program for the elimination of all existing cross-connections as well as the prevention of future cross-connections.

The Brown Deer Water Utility delivers safe, high-quality drinking water every day. However, outside contaminants and pollutants have the ability to degrade the quality of the drinking water supplied and serve as a health and safety risk. The Brown Deer Water Utility's Cross-Connection Control (CCC) program is designed to continue to safeguard public health and keep the water system safe from contaminants and pollutants.

Brown Deer Utility operators perform inspections of all commercial, industrial, multi-family, public authority, and residential buildings connected to the water supply to detect actual and potential cross connections and make recommendations for the installation of backflow prevention devices or assemblies where necessary. These inspections happen on varying frequencies based on the hazard level of the facility.

Residential Inspections

The Brown Deer Water Utility coordinates residential inspections with the Public Service Commission (PSC) of Wisconsin’s mandatory meter replacement program. Therefore, when a residential water meter is replaced at the end of its 20-year lifespan, a cross-connection inspection will also be performed.
