The City of Warrenville will begin its annual fall hydrant flushing program from September 29 through October 31, 2025, Monday through Friday between 7:00 a.m. and 3:30 p.m.
Hydrant flushing is a regular maintenance activity that helps:
During flushing, water may look cloudy or discolored or contain some sediment for a short time. Running your faucets will help clear it up.
Water is safe to drink during this time, even if it looks different.
