Replacing a water heater in Fairview Heights.
Fairview Heights doesn't say whether a straight water heater swap needs a permit or post a fee, so call to check. Its Land Use & Development Department issues permits and has a city plumbing inspector. Ameren Illinois handles both electricity and gas here. Water comes from O'Fallon's system for many homes and from other providers in other parts of the city.

It depends on your address. Many residents are on the City of O'Fallon Water Department, which buys from Illinois American Water. Others get water through Caseyville or from Illinois American directly.
