What We Do
The MWRD will protect the health and safety of the public in its service area, protect the quality of the water supply source (Lake Michigan), improve the quality of water in watercourses in its service area, protect businesses and homes from flood damages, and manage water as a vital resource for its service area.
Thanks to the work of the MWRD, water quality has improved dramatically in Chicago area rivers and streams. The source of the region’s drinking water in Lake Michigan is protected through more than a century of the MWRD’s work.
The MWRD treats wastewater from Chicago and 128 surrounding communities at our seven water reclamation plants.
The Metropolitan Water Reclamation District's annual budget is a $1.4 billion financially responsible spending plan that invests in public infrastructure, addresses regional and localized flooding issues, and continues a commitment to fully funding the Retirement Fund.
The MWRD values the communities we serve and we prioritize environmental justice, fair treatment and meaningful involvement in our work.
Native landscaping can help reduce flooding, protect water quality and provide habitat for wildlife.
The Tunnel and Reservoir Plan is a system of deep, large diameter tunnels and vast reservoir designed to reduce flooding, improve water quality in Chicago area waterways and protect Lake Michigan from pollution caused by sewer overflows.
