MMSD

The Milwaukee Metropolitan Sewerage District (MMSD) is a regional government agency that provides water reclamation and flood management services for over 1 million people in 29 communities in the Greater Milwaukee Area.

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 a national 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 98.4% record since 1994 of capturing and cleaning wastewater from 29 communities in a 423-square-mile area. Many metropolitan areas struggle to capture and clean the national goal of 85% of the rain and wastewater entering their sewer systems.
