The purpose of flushing is to remove sediment and mineral deposits that settle on the bottom of water mains and to verify proper operation of hydrants. Discolored water can be drawn into homes or businesses if water is used during or immediately after area water mains are flushed. The discolored water results from naturally occurring minerals that will be dislodged during flushing. This mineralized water is not harmful to drink, but could cause laundry stains. If you have any questions or concerns about the water main flushing, please call the Romeoville Water Department at (815) 886-1870.
