The Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) is an award-winning, special-purpose district responsible for treating wastewater and providing stormwater management for residents and businesses in its service area, which encompasses 882.1 square miles and includes Chicago and 128 suburban communities throughout Cook County.

The District has seven water reclamation treatment plants (WRPs). Four of the WRPs have anaerobic digestion systems, including one of the largest WRPs in the world. As part of its Resource Recovery Program, the MWRDGC accepts non-hazardous high strength liquid organic material (HSOM), high strength liquid waste (HSLW), vegetative material, such as yard waste, and wood chips. The MWRD uses these materials to produce its exceptional quality composted biosolids and renewable energy (biogas). It also produces fertilizer from phosphorus recovered during the water treatment process to reduce its release into the waterways. More>>
