Environmental Stewardship

Milwaukee has an abundant water resource in Lake Michigan, which contributes to a high quality of life and a reliable supply of fresh drinking water. We use Lake Michigan water and return it to the lake.

As a steward of the resource, the Milwaukee Water Works uses sustainable practices to reduce its energy, carbon and water footprints while purifying and pumping the water. We focus on supply-side conservation, water accountability, energy conservation, operational efficiency and consumer advocacy to prevent water waste. 

Environmental Collaboration Office

The Environmental Collaboration Office, or ECO, strives to make Milwaukee a world class eco-city. ECO develops practical and racially equitable solutions that improve people’s lives and the economy while working to protect and restore the natural ecosystems that support our long-term prosperity.  ECO collaborates with the community, develop global partnerships, offer award-winning programs, and implement the ReFresh Milwaukee sustainability plan. ECO is also managing development of Milwaukee's Climate and Equity Plan

Safely Dispose of Unused Medicine, Household Hazardous Waste, and Electronics A clean water source is one of the barriers to protect public health.

These compounds are present in the lake water but none have been found in treated drinking water.
