A Contractor Information and Outreach Meeting was held on August 9, 2023. The meeting focused on the Dredged Material Management Facility background, key components, supplier diversity and workforce development and the bid timeline. The project is anticipated to bid in the 4th quarter of 2023, Listen to the recording here.

Over the last few months, there have been some updates on the design and MMSD has submitted permit applications to the DNR. As we move forward, we will be receiving permit comments and continuing to move that design forward. The plan is to solicit bids from companies for the construction of the Dredged Material Management Facility in the winter. Watch the May 2023 update video and the June 2022 virtual walking tour of the Dredged Material Management Facility.to learn more.
To build the Dredged Material Management Facility, we first need to relocate a combined sewer overflow outfall. Watch the October 2022 Combined Sewer Overflow Outfall #195 Relocation project video to learn more.

The Milwaukee Metropolitan Sewerage District (MMSD) is partnering with the City of Milwaukee, Wisconsin Department of Natural Resources (WDNR), We Energies, and Port Milwaukee to create a new Dredged Material Management Facility (DMMF) in the Milwaukee harbor. When it is completed, this facility will provide safe, secure containment for 1.9 million cubic yards of sediment removed from the Milwaukee, Menomonee, and Kinnickinnic Rivers.
Over time, contaminated sediment has accumulated in the downstream portions of our rivers. The Milwaukee Estuary (the area where Milwaukee’s three rivers converge) was designated an Area of Concern (AOC) by the EPA in 1987 due to historical contamination. Since then, there have been ongoing efforts to clean up Milwaukee’s Estuary.
The existing Confined Disposal Facility located north of the Lake Express ferry dock is nearly at capacity and does not have available space for the sediment that will be removed from the rivers as part of the Milwaukee Estuary AOC Initiative. The new DMMF will provide the needed capacity for storage of this sediment.
The DMMF is a cost-effective approach that manages the contaminated sediment and protects both river and lake health. In addition to reducing the cost to remove and store the sediment, construction of the DMMF at the lakefront bypasses the negative environmental impacts of hauling the material to a new landfill. If the material was trucked to a landfill instead of to the DMMF, there would be increased truck traffic and the need for landfill expansion.
Once constructed, the DMMF will be owned and operated by the Port of Milwaukee.
The DMMF project is part of a larger initiative to clean up the Milwaukee Estuary Area of Concern (AOC). Learn more about the AOC by watching this John Gurda video or visiting the Waterway Restoration Partnership website.
