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 requires us to think ahead. 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.
Since 2006 the Illinois Department of Natural Resources has tasked the Water Survey with leading regional water supply planning activities for 11 Illinois regions. Learn more about the team that carries out this important activity.
