Illinois American Water Commences Critical Annual Maintenance in Metro East Region
BELLEVILLE, Ill. – Illinois American Water is set to begin its comprehensive annual maintenance program in the Metro East water system on August 17th. This vital initiative, slated to continue through the end of September, encompasses essential tasks such as testing and flushing fire hydrants, alongside a temporary modification in water treatment protocols. These proactive measures are designed to ensure the uninterrupted delivery of high-quality water and robust fire protection services to both residential and commercial consumers across the region.
The maintenance program involves two key components: water main and fire hydrant flushing, and a temporary shift in water treatment at its East St. Louis and Granite City facilities.
**System Integrity: Flushing Water Mains and Fire Hydrants**
A cornerstone of the annual maintenance involves flushing the water system and rigorously testing fire hydrants. This process simulates a high-velocity flow of water through the mains, crucial for maintaining optimal water quality and ensuring the reliability of fire suppression infrastructure. During these flushing operations, customers may temporarily experience a slight reduction in water pressure or observe brief instances of discolored water. If discolored water is encountered, it is advised to avoid using laundry facilities and to briefly run cold water taps until clarity is restored.
This systematic approach to infrastructure maintenance is not merely a procedural step but a critical investment in the long-term health and resilience of the water supply network. By physically clearing potential sediment buildup and verifying the operational status of hydrants, Illinois American Water reinforces its commitment to public safety and service reliability, particularly in its role supporting emergency response capabilities.
**Optimizing Disinfection: A Temporary Water Treatment Adjustment**
In conjunction with the infrastructure flushing, Illinois American Water’s dedicated water quality team will implement a temporary change in its water treatment process. The company will be switching to a form of chlorine known as “free chlorine,” which is distinct from combined chlorine by its absence of ammonia. This transition will occur at the water treatment plants serving East St. Louis and Granite City.
Free chlorine is a more potent disinfectant and is often utilized by water utilities during periods of system flushing. While chlorine is a standard and rigorously monitored disinfectant in public water systems, the shift to free chlorine is a strategic decision to enhance disinfection efficacy during the maintenance period. Customers may notice a temporary change in the taste or odor of their water due to this adjustment, which is a normal and expected outcome and poses no health concerns.
Recognizing the specific needs of sensitive facilities, Illinois American Water has proactively communicated this change to institutions equipped with specialized water purification systems, including hospitals and dialysis centers. Individuals with particular health concerns or who rely on specialized medical equipment are encouraged to consult with their healthcare providers for personalized guidance.
**Extensive Service Area and Customer Outreach**
This comprehensive maintenance program will extend to all direct service communities, including Belleville, Brooklyn, Cahokia Heights, Canteen Township, East St. Louis, Fairmont City, Granite City, Madison, Lovejoy, Nameoki Township, National City, Sauget, Shiloh, St. Clair Township, Stookey Township, Swansea, Venice, Washington Park, and Livingston. Furthermore, the initiative will also impact wholesale communities served by Illinois American Water, such as Bond Madison Water Company, Cahokia Heights, Caseyville, Glen Carbon, Metro East Municipal Joint Action Water Agency (MEMJAWA), Millstadt, Mitchell Public Water District, O’Fallon, Pontoon Beach, Pontoon Beach Water District, and Scott Air Force Base.

Direct service customers are being notified through the company’s established notification system, which includes personalized calls, emails, and text messages based on individual preferences.
