Due to projected growth of the population and economy, Illinois could require 20 to 50 percent more water in coming decades. Ensuring adequate and reliable supplies of clean water for all users at reasonable cost requires us to think ahead to the year 2050. As a state, we need to know how much water will be available, how much water we will need, what the options are for providing additional supplies, reducing demand and what the impacts and costs will be.
In January 2006, Governor Rod Blagojevich signed Executive Order 2006-01, requiring the Illinois Department of Natural Resources (IDNR) to lead state and regional water-supply planning activities. To begin that effort, the State initially selected two areas for priority pilot planning: northeastern Illinois and east-central Illinois, and then added a third area: Kaskaskia Region.
