Metropolitan Water Reclamation District of Greater Chicago

Located in Lockport, Ill., the MWRD built the Lockport Powerhouse in 1907 which marks the southern point of the MWRD-managed Chicago Area Waterway System (CAWS). The Powerhouse is located where the Chicago Sanitary and Ship Canal connects with the Des Plaines River. The facility is an integral part of the MWRD's work to manage the CAWS to reduce the risk of flooding throughout the MWRD service area. The Powerhouse allows the MWRD to control the levels of the waterways and provides financial benefits from hydroelectric power generation. The water flowing through the facility is harnessed by two turbines to provide a safe and environmentally friendly hydroelectric energy source that is sold back to Commonwealth Edison. The MWRD earns approximately 1 million dollars per year from generating hydroelectricity at Lockport Powerhouse.
