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 that goes above and beyond requirements. Crystal-clear Milwaukee water is provided fresh and pure 24 hours each day. 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. A public utility belongs to all of us. Revenue is reinvested in utility infrastructure.

While providing fresh, safe water for a healthful quality of life, we provide commercial and manufacturing business, and research with a reliable supply of high-quality water at a low price.

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.

The Water Research Foundation (WRF) awarded its Outstanding Subscriber Award for Applied Research to the Milwaukee Water Works in June. The award honors member utilities that have successfully applied WRF research to make notable improvements to their water treatment, delivery and management processes. The award "celebrates the persistence and dedication of some of WRF's most influential partners." The Milwaukee Water Works also was featured as the WRF observes its 50th anniversary in 2016. Milwaukee continues to participate in WRF projects benefitting the drinking water community, as seen in a video here. Read the Milwaukee Water Works and Ozone story.

A recent study by Harvard University found drinking water supplies for at least six million people in the U.S. contain Perfluorinated Compounds, or PFCs, at levels that exceed the U.S. Environmental Protection Agency lifetime health advisory. PFCs are not found in Milwaukee's source water, Lake Michigan, nor are any found in our treated drinking water.

Protecting Public Health

A leading national example of partnerships between health departments and drinking water utilities and other public health stakeholders is the Milwaukee Inter-Agency Clean Water Advisory Council (IACWAC). The group was endorsed by Milwaukee Common Council legislation in 1994 and charged with the overall coordination of water quality issues in the community.

Cross-Connection Control

A cross-connection is any actual or potential physical connection between a drinking water system and a source or system of non-drinkable water or substances. As Milwaukee’s water utility, we are responsible for making sure the water delivered to your home is safe to drink and use. Please help us keep water safe in your home and our water system safe from potential contamination due to cross-connections.
