Peoria, Ill. (October 10, 2025) — On Sunday, October 12, Illinois American Water will begin its Peoria District annual maintenance program that includes testing and flushing fire hydrants in addition to a temporary change in water treatment. This annual maintenance work supports continued delivery of quality water and fire protection to homes and businesses. The maintenance program will continue through the end of October.
WATER MAIN AND FIRE HYDRANT FLUSHING
Flushing the water system and checking hydrants, in support of fire protection, entails sending a rapid flow of water through the water mains. While Illinois American Water crews are testing and flushing the system and fire hydrants, customers may experience a temporary drop in water pressure or draw some discolored water for a short period. If discolored water occurs, it is recommended that customers refrain from doing laundry and let their cold water run briefly; the water should clear up on its own.
TEMPORARY WATER TREATMENT CHANGE
In addition to the water main and hydrant flushing, Illinois American Water’s water quality team will be switching water treatment to a form of chlorine known as “free chlorine,” which does not contain ammonia. This stronger disinfectant is typically used by water utilities when flushing water mains and fire hydrants. Chlorine is commonly used in public water systems as a disinfectant and is monitored closely by our water quality professionals.
During the temporary water treatment change, customers may experience a more noticeable chlorine taste or odor in their water. There is no reason for concern. This is due to the switch in chlorine types. Institutions with additional water purification filters for special needs, for instance hospitals and dialysis centers, have been contacted about this water treatment change. Anyone with questions about their personal health and health care equipment should reach out to their healthcare provider.

The maintenance program will occur in all communities served directly by Illinois American Water in the Peoria, Bartonville, West Peoria, Rome, Woodland Heights and surrounding areas.
