This fact sheet summarizes data collected by the Illinois
Water Inventory Program for the water reporting year 2012.
Water use data is presented in two sectors, public water supply
and the self-supplied industry.
During 2012, reported water withdrawals in Illinois totaled
40,230 million gallons per day (mgd), with groundwater
totaling 480 mgd and surface water 39,750 mgd. Public water
supplies (PWS) withdrew 1,509 mgd and self-supplied industries (SSI) withdrew 38,721 mgd. Electric power generation
is the state’s number one water user, making up a majority of
water withdrawals in 2012. Excluding power generation, which
is generally a non-consumptive use of water, SSI withdrawals
totaled 477 mgd.
