How can I Start/Stop Service?

The O’Fallon Utility Billing Department provides Water and Sewer Service to most O’Fallon residents and some unincorporated areas, and also provides water service for most of Fairview Heights. In order to initiate or discontinue service, please call the office at 618-624-4500 and a representative will assist you. With technology rapidly changing, the water department plans to have this service available online in the future.
