Why is the Water Department flushing hydrants?
Hydrant flushing is an important part of maintaining the City’s water distribution system. Flushing hydrants are one way the Water Department maintains the highest quality water possible. Sediments will “settle out” and deposit in the water mains. Occasionally after a period of time, sediments will get stirred up and in turn cause cloudy or discolored water. Flushing removes the sediments. Do these sediments make our water unsafe? No, calcium carbonate is naturally occurring in our source water. As a part of the water treatment process it is removed. The finest particles may settle out in the water mains. The City of St. Charles Water Division routinely tests all areas of the city to ensure safe water supply. What should I do if water department crews are flushing in my area? If water department crews are flushing, refrain from using water at that time.
