Milwaukee Metropolitan Sewerage District

Protecting public health and the drinking water supply for millions of people takes the expertise of hundreds of specially skilled and dedicated employees. The Milwaukee Metropolitan Sewerage District (MMSD) is a highly regarded national leader in wastewater treatment, flood management, and green infrastructure. MMSD is a regional governmental agency serving 1.1 million people in Greater Milwaukee. Our mission is to protect public health and the environment through world-class, cost-effective water resource management, leadership, and partnership. Join our diverse team and support your community while protecting our environment. A recipient of the U.S. Water Prize and many other awards, we are most proud of our record for capturing and cleaning 98.5% wastewater, since 1994, from our 28 communities in a 423-square-mile area. Many metropolitan areas struggle to capture and clean the national goal of 85% of all the rain and wastewater that enters their sewer systems.
