Backflow Prevention Device

  • Clean water is important to everyone.  One cross-connection can compromise the quality of water.  A cross-connection occurs when potable water meets with the outside environment.  Any bathtub, sink, washer, dishwasher, toilet or garden hose is a potential cross-connection.
  • A backflow device must be installed after the meter (see below for approved devices)
  • All backflow devices are mechanical and will eventually fail.  Testing is crucial to ensure the safety of the public water system.  Each device should be tested annually.
  • Colorado State regulations require your backflow devices be tested each year.  If you are not sure when your device was last tested, please call the District office at (970) 923-2056.  More information about selecting a Certified Backflow Technician is available at
