About Us

The Milwaukee Metropolitan Sewerage District (MMSD) is a regional government agency that provides water reclamation and flood management services for about 1.1 million people in 28 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 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 98.4%, since 1994, for capturing and cleaning wastewater from 28 communities in a 411 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.

IIn 2017, MMSD created the Fresh Coast Resource Center (FCRC) to empower people, homeowners, businesses, nonprofits, and government to take an active role in protecting our most precious natural resource: water. By helping the community to protect our rivers and Lake Michigan, we work to achieve our goal of capturing the first 0.5 inches of rainfall in our service area. This helps keep excess water out of our sewers which helps prevent sewer overflows and reduce runoff pollution. The FCRC is here to assist the community by providing the inspiration, education, and tools needed to create successful green infrastructure projects such as:

• Rain Barrels
• Rain Gardens
• Porous Pavement
• Bioswales
• Green Roofs
• Natural Landscaping
• Funding Opportunities

Since 1926, the MMSD has safely recycled the nutrient-rich microbes resulting from the water reclamation process into Milorganite slow-release nitrogen fertilizer. The production of Milorganite fertilizer is one of the nation’s oldest recycling efforts.

We have a vision by 2035 to significantly reduce our energy consumption to have 80 percent of our energy supplied from renewable sources. Milorganite is already using alternative energy sources such as solar, landfill gas, and digester methane in its production facilities to help achieve this goal.
