As part of the regular maintenance to the City’s water distribution system, the Public Works Water Division performs seasonal hydrant flushing. By simply flushing hydrants to allow water to flow rapidly through them [in a controlled manner], water quality is improved and mineral build-up in the water mains is minimized. Hydrant flushing also ensures that hydrants are ready for emergency use.
Hydrant flushing signs are posted in advance throughout the affected area.
St. Charles is divided in half for hydrant flushing: West side and East side, which is divided by the Fox River. The hydrant flushing schedule is as follows:
Northwest Quadrant will be done during the first part of the week of October 3
Southwest Quadrant will be done during the second part of the week of October 3
Northeast Quadrant will be done during the first part of the week of October 10
Southeast Quadrant will be done during the second part of the week of October 10
Please watch for signs announcing hydrant flushing which will be posted by the Water Division. Flushing may start as early at 5 a.m. and continue through 4 p.m.
Water is safe to use and consume during hydrant flushing, however, residents may temporarily experience rusty colored water. Public Works recommends residents take the following steps during hydrant flushing:
- It is best to limit your water use, if possible.
- If you experience rusty water, 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 a stain removal product at no cost to residents at the following facilities:
- Public Works located at 1405 S. 7th Avenue
- City Hall Front Reception Desk located at 2 E. Main Street
