Water Division

The Water Division of the Public Works Operations Group provides preventive maintenance for the water system (including flushing the fire hydrants and exercising valves); takes care of repairs to the water system (including meters, valves, fire hydrants, pump stations, storage tanks, and broken water mains); installs service taps and meters, activates and deactivates service, and performs leak checks; maintains system-monitoring devices and extracts samples and performs tests to assure water quality.

If you have any questions, please email [email protected] or call 624-4500, extension 3.

In order to reduce costs the division uses AMR which stands for Automatic Meter Reading. Water meters are located in the ground at each property and have an ERT (Encoder-Receiver-Transmitter) mounted under the meter lid that facilitates radio reading. Please be careful around the water meter when mowing or doing other lawn maintenance to avoid damaging the equipment. Damaged water meter components are expensive to replace and can result in costly charges to the customer.

O'Fallon purchases water from Illinois-American Water Company's plant in East St. Louis.  The Division brings water to 18,000+ water customers in both O'Fallon and Fairview Heights through City pipelines.
