Illinois American Water to Conduct Fire Hydrant Flushing and Treatment Change


This week, Illinois American Water will begin its an annual maintenance
program, which includes testing and flushing fire hydrants in addition
to a temporary change in water treatment. This work helps to ensure
continued water quality and fire protection to homes and businesses; it
will occur across the Metro East water distribution system for the next
two months.

While Illinois American Water crews are testing and flushing fire
hydrants, customers may experience a slight drop in water pressure or
draw some discolored water for a short period of time. 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.

In addition to the hydrant maintenance and flushing, Illinois American
Water's water quality team will be switching 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

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.

Institutions with additional water purification filters for special
needs, for instance Hospitals and Dialysis Centers, have been contacted
about this work and are aware of the treatment change. Anyone with
questions about home health care equipment should reach out to their
healthcare provider.

The maintenance program will occur in all direct service communities in
the Belleville, East St. Louis and Granite City areas and also
sale-for-resale (wholesale) communities. Customers are being notified of
this work via media outreach, customer calls and information on Illinois
American Water's website at
Information is also provided to customer service center representatives.
