The City of St. Charles is flushing hydrants beginning April 1 and continuing through May 3. Please note hydrant flushing could temporarily cause water discoloration, even for homes outside the particular flushing area. The discoloration is caused by minerals that get stirred up in the water mains.
Public Works performs hydrant flushing as part of the regular maintenance to the City's water distribution system. Flushing water through the mains helps reduce mineral build-up and ensures the hydrants are ready for emergency use. The City website has a list of frequently asked questions about hydrant flushing.
St. Charles is divided into zones for hydrant flushing. Main Street (IL Rt 64) divides the north/south areas, and the Fox River divides the east/west. Outer Zones: Northwest, Southwest, Northeast, Southeast. Inner Zones: River Valley East and West.
Hydrant Flushing Schedule:
- River Valley East & West - Monday April 1- Friday April 5
- Northwest & Southwest - Monday April 8 - Friday April 12
- Southeast & Southwest - Monday April 15 - Friday April 19
- Northeast - Monday April 22 - Friday May 3
Signs announcing hydrant flushing will be posted in affected neighborhoods. Flushing may start as early as 5 a.m. and continue through 4 p.m
Discolored Water Possible
Please note water is safe to use and consume during hydrant flushing. However, water may temporarily be rusty colored. Consider the following actions during hydrant flushing:
- Limit water use, if possible.
- If water appears discolored, wait until flushing has subsided then run the cold water tap in your bathtub or utility sink until it runs clear (or in 10-minute increments).
- Remember rust-colored water is safe, but it may stain laundry. If this happens, keep clothes wet and treat them with stain remover.
The City offers stain remover at no cost to residents at the following facilities:
- Public Works, 1405 South 7th Avenue
- City Hall, Reception Desk, 2 East Main Street
