Dredged Material Management Facility (DMMF)

Project Update October 2024: The Dredged Material Management Facility (DMMF) construction is continuing. Approximately 400 of the 950 circular piles have been installed along the south, west and north walls. Watch the video for a more comprehensive update.

Most of the contaminated sediment from Milwaukee’s rivers is planned to be placed in the proposed DMMF. A DMMF is an area specifically designed and engineered for the containment of dredged material and control of potential releases of contaminants to the environment.

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.
