After nearly 24 hours of heavy rainfall on a near frozen ground across Cook County, the Metropolitan Water Reclamation District of Greater Chicago’s (MWRD’s) Tunnel and Reservoir Plan (TARP) on Friday continued to operate as designed, by capturing stormwater, sewage and additional snowmelt and keeping it out of local waterways and local communities serviced by combined sewer systems.

The flag will be raised at all seven water reclamation plants. 

Heavy rain is expected in the Chicagoland area. Reduce your use of water before, during and after the storm to help prevent flooding and protect water quality.

The Metropolitan Water Reclamation District issued an Overflow Action Alert Thursday, January 30 2025 ahead of expected rainfall in the Chicago area in an effort to prevent overflowing of the city's sewer systems.

For decades, the conversation around climate change has focused on mitigation. By attempting to limit carbon emissions and other human practices contributing to environmental change, you can limit the effects.

The proposed project could cover nearly one-square-mile area along Deer Creek and Third Creek within the Little Calumet River Watershed near Glenwood and Ford Heights, where stormwater storage can help mitigate increasing flooding concerns.
