Water Division

The City of Wentzville purchases the majority of its water from PWSD #2 of St. Charles County.  The City Water Division then distributes an average of 5 million gallons of water daily to the residents, businesses, and industries of the City of Wentzville. This is accomplished by the efforts of highly qualified water, state-certified operators maintaining over 250 miles of water mains.  

Lawn Irrigation Tips:  Many irrigation companies set a three-day M-W-F schedule for irrigation systems.  To assist the City in balancing demand, backflow testing reports are due annually by June 1.  When setting up your lawn irrigation system, consider a four-day (T, Th, Sat, Sun) cycle with shorter watering times. 

To report a non-emergency concern, call (636) 639-2121 during regular business hours or use the online Concern System any time.

For after-hours emergencies, please call Public Works at (636) 327-5102 and follow directions to dispatch 24-hour service.
Billing questions may be directed to the Utility Service Center at (636) 639-2155.
