Drinking Water

The Village of Carol Stream purchases its drinking water from the DuPage Water Commission. The Commission is a coalition of suburbs that was formed to develop a source of reliable, high-quality water, apart from local wells. The Commission receives its water through the City of Chicago from Lake Michigan.  For more information on the DuPage Water Commission, click on the icon below: 

We are required to provide our customers with information concerning the quality and source of our drinking water, the results of water sampling, and our compliance with drinking water regulations.  Click on the link below to access this information:
