O’Fallon Utility bills get a makeover
Residents who use City of O’Fallon utilities including trash, water and/or sewer services will see a new look on their utility bills. The improved design is easier to read and provides users with more information on the back of the bill. Residents will continue to receive one combined bill if they utilize more than one of the trash, water or sewer services. Utility rates and calculations are not impacted by this change in any way. For questions about the new bills, call 636-379-5488 or check out the PDF below for a sample utility bill.
O'Fallon TV
O'FallonTV is also available on Charter Spectrum TV Channel 991 and AT&T U-verse Channel 99.
O'Fallon's mosquito control program
Aside from being itchy and annoying mosquitoes can carry Mosquito-borne diseases. Although relatively rare, there are cases of mosquito-borne illness reported every year throughout the United States. For more information mosquito-borne illnesses, please visit www.cdc.gov. Even though illnesses are rare here, the fact remains, mosquitoes are annoying, can disrupt outdoor plans, force people indoors and hurt!
The City of O’Fallon has a mosquito control program in place. Our dedicated professionals will treat any street or neighborhood of the City upon request of the residents or Homeowners’ Association. To request a spray, just call 636-379-5553 or email citizensfirst@ofallon.mo.us. Please note: Our trucks will spray as they drive down the street. Our crews cannot treat individual yards. Each call will result in a single spray. To have your area treated a second time, you must call again.
