Do you support investing in long-term infrastructure projects to clean up local polluted rivers?

The Milwaukee Metropolitan Sewerage District has officially opened the Dredged Material Management Facility. This project provides a secure, permanent location to contain contaminated sediment removed from the Milwaukee, Menomonee, and Kinnickinnic Rivers.

Why it matters

The facility prevents hazardous sediment from re-entering the local environment, marking a key step in restoring the long-term health of regional waterways. It is a critical component of the broader cleanup of the Milwaukee Estuary Area of Concern.

The 42-acre facility can hold sediment volume equivalent to 13 football fields at a depth of 50 feet. It was completed ahead of schedule and $26 million under the projected budget.

The players

Milwaukee Metropolitan Sewerage District

This regional government agency provides water reclamation and flood management services to the Milwaukee area.

Port Milwaukee

This department manages the city's harbor and industrial properties along the Lake Michigan shoreline.

Environmental Protection Agency

This federal agency oversees national environmental policy and coordinates large-scale hazardous waste remediation efforts.

The details

Owned and operated by Port Milwaukee, the facility is the product of a massive partnership including the EPA, WDNR, and We Energies. It is designed to safely sequester dredged pollutants, ensuring they do not leak into the surrounding environment as the cleanup of the Milwaukee Estuary continues.

The Dredged Material Management Facility opened on October 20, 2026.
The facility is projected to take at least 30 years to fill completely.
Settling and compaction of the stored material will take 10 years or more after the facility is full.

The Big Picture

The new dredging site serves as the primary containment infrastructure for the Milwaukee Estuary Area of Concern. This facility follows the established federal framework to accelerate the ecological recovery of the region's three major rivers.

The completion of this project advances the $450 million river cleanup, which aims to improve water quality and ecological safety for local residents. By removing legacy contaminants, the initiative clears the path for improved recreational and environmental health in the city's river system.

The takeaway

This facility provides a long-term solution to environmental hazards that have long impacted regional water health. Residents can expect continued progress on river remediation projects as the site becomes the central hub for dredged materials.
