Thornton Composite Reservoir will benefit 556,000 people in 14 communities throughout the South Side of Chicago and south suburbs in Cook County; protect 182,000 structures, such as homes, businesses and other facilities; and improve water quality in the Calumet Rivers and Calumet-Sag Channel. The reservoir is part of the Metropolitan Water Reclamation District of Greater Chicago’s Tunnel and Reservoir Plan (TARP), which is designed to improve water quality and prevent flooding caused by combined sewer overflows. TARP, also known as the “Deep Tunnel,” consists of more than 100 miles of tunnels deep below the surface of the Chicago region and three reservoirs designed to capture and hold stormwater and combined sewage for treatment at water reclamation plants.
