What We Do

Protecting public health and the drinking water supply for millions of people takes the expertise of hundreds of specially skilled and dedicated employees. MMSD is highly regarded nationally as a leader in wastewater treatment, flood management, and green infrastructure. A recipient of the U.S. Water Prize and many other awards, we are most proud of our record of 98.5%, since 1994, for capturing and cleaning wastewater from 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.
