Communities across the globe face an increasing array of water resource challenges and the Chicago region is not immune. Despite access to Lake Michigan, significant portions of the region are already encountering water supply and quality issues. To maintain a long-term drinking water supply, ON TO 2050 recognizes the need to coordinate and conserve its shared water supply resources. Assessing long-range forecasted demands in the context of available water supply can inform local and regional planners about the sufficiency of water supply and encourage actions that conserve water, protect supply, and/or pursue alternative drinking water sources.
CMAP, in partnership with Illinois-Indiana Sea Grant and University of Illinois Extension, developed the ON TO 2050 Regional Water Demand Forecast to inform decisions about land use, transportation, and infrastructure that affect water supply and demand. This forecast builds on the previous regional water demand forecast for Water 2050, Regional Water Demand Scenarios for Northeastern Illinois: 2005-2050 (2008) and is based on the ON TO 2050 Socioeconomic Forecast. The forecast is presented in 5-year intervals to the year 2050 at the municipal, county, and regional scale, as well as by drinking water source and sector for the seven counties of the Chicago region. It focuses on the largest water sectors -- residential public water supply, non-residential water supply, and domestic self-supply -- and provides individual forecasts for 245 municipalities in the region. As a long-range water demand forecast, it is intended for planning purposes and is not suited for assessing infrastructure capacity or peak demands at the system level.
Forecast data is available for download on the CMAP Data Hub. For additional information on the water demand forecast methodology and data, contact Nora Beck (firstname.lastname@example.org or 312-386-8677) or Margaret Schneemann (email@example.com or 312-676-7456).
