Abstract: Existing combined sewers in the Chicago area discharge a mixture of storm-water runoff and sewage to the rivers approx 100 times/yr and on occasions overload the river system making it necessary to reverse the flow of the river system into Lake Michigan. Storm-water and drainage in the combined sewer area will be managed by a system of tunnels and reservoirs under construction. In the separate sewered area, a system of reservoirs, channel improvements, and land treatment is being implemented; and, to reduce the erosion and siltation problems of the rivers and streams, on-site detention in new residential and industrial developments is being required. Thus, the goals of Chicago's Areawide Wastewater Management Program are comprehensive, including simultaneous flood control and water quality improvements.
