During this time Illinois American Water will switch to a form of chlorine known as “free chlorine,” which does not contain ammonia. This stronger disinfectant is typically used when flushing water mains. Chlorine is commonly used in public water systems as a disinfectant and is monitored closely by our water quality professionals.

During the temporary 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.  Annual fire hydrant-water main flushing will also be taking place to ensure continued water quality and fire hydrant operation for public safety.

When Illinois American Water crews are working, customers may experience a temporary drop in water pressure or draw some discolored water for a short period of time. If this occurs, customers should simply let the water run briefly and the situation should clear up on its own.
