Project Update September 2025:
In September, we reached a big milestone on the Dredged Material Management Facility (DMMF) — the final wall is now in place, officially closing in the site!
But we’re not done yet — there’s still a lot of work ahead, and the project won’t be fully complete until 2026.We put together a new video walking through the key steps of building the DMMF. Check it out to see the progress so far!
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.
