In April, Public Works Utility Division crews will flush fire hydrants citywide. The entire process takes about three weeks. In general, hydrant flushing is completed twice a year to maintain water quality, and ensure hydrants are properly working. If you have any questions regarding this program, please contact the Warrenville Public Works Department at 630-393-9050.
