Willowbrook Water Supply

The Village of Willowbrook receives one hundred percent (100%) of its daily potable water supply from Lake Michigan.  As a member of the DuPage Water Commission, the Village has been receiving an average of approximately 1 million gallons of water per day since January 1, 1992 and is able to provide enough water to meet even the highest demand on the warmest summer days.  Lake Michigan water is a higher quality source than the combination deep and shallow wells that have provided water to Willowbrook in the past. The Village continues to maintain its deep well, which could operate as a reliable backup source in an emergency.
