Water Demand

A myriad of uses exist for water in Illinois such as drinking, cooking, cleaning, industry, irrigation, power generation, waste treatment, recreation and even transportation. In addition there is a need to support aquatic habitats and wildlife. Included here is information such as how much water is used in Illinois, who uses the water, a rough geographic distribution of that use, potential future demands from a growing population and economy, and where that demand may occur.
