Water Quality

The Milwaukee Water Works (MWW) is recognized as a national leader for providing safe, high-quality drinking water, and for our water quality monitoring program. We treat Lake Michigan water with ozone disinfection, biologically active filtration, and chloramine disinfection. Since 1993, the Milwaukee Water Works has invested $508 million in its infrastructure, to ensure a reliable supply of pure, safe drinking water.

Water quality and operations are regulated by the U.S. Environmental Protection Agency (EPA) and the Wisconsin Department of Natural Resources (DNR), and the Wisconsin Department of Health Services. Rates are regulated by the PSC.

Lead & Copper Compliance Monitoring for 2017 found Milwaukee’s water in full compliance with quality regulations. The sampling is required every three years by the Wisconsin Department of Natural Resources.
