Abstract:Plans were developed for optimal use of available groundwater and surface water resources for adequate and dependable water supply to all towns in Cook, DuPage, Kane, Lake, McHenry, and Will Counties. An efficient water-demand model, based on a town's population and industrial employment, was used for future demand projections. The potential yield of sand and gravel and Silurian dolomite aquifers was investigated. Cost functions were developed in terms of July 1980 dollars for wells, pumps, water conveyance system components, reservoirs, and treatment plants. Out of a total of 273 towns, 96 are presently served with lake water either directly or from Chicago. The groundwater supply from shallow aquifers is adequate for 85 towns. Thus, 92 towns need other sources of water if the safe yield of the deep sandstone aquifer is not to be exceeded. Six optimal regional systems to meet these demands were developed. The Fox Valley system considers conjunctive use of groundwater, as well as direct supply from Lake Michigan. The Kankakee River system considers water withdrawal from the river near Wilmington. The other four systems — Lake County, Northwestern Cook County, DuPage County, and Southern Cook County — obtain water from the lake directly or from Chicago. With the proposed individual groundwater and regional surface water systems, there is ample water for all towns in northeastern Illinois to meet their water demands for the next 30 or more years, without mining of the deep aquifer.
