Backflow / Cross Connection Program

City of Aurora has entered into a contract with Hempel Backflow to conduct testing throughout the City at a reduced rate.  Residents who have a device have been notified of this program, if they choose to have their test conducted by another tester, the test must be completed and results submitted to City Hall by no later than May 1 of each year. 

State law requires water systems to have an approved backflow assembly if a cross connection exists with systems that can introduce contaminants into the public water system.  This valve assembly will be located between the city water meter and your home or building.  The purpose of this valve is to prevent pollutants or contaminates from entering the public potable water system.  These backflow assemblies must be tested yearly by a state certified cross connection inspector.  The annual testing report must be submitted to Aurora City Hall each year.  

The following list has common examples of when back flow protection is required.  Oregon Health Authority (State of Oregon) maintains a more comprehensive list.

  • Hose bibs without a hose bib vacuum breaker 
  • Irrigation or Sprinkler system                               
  • Auxiliary water supplies (i.e. unapproved wells)
  • Swimming pools directly connected (auto-fill)
  • Post mix beverage machines using carbon dioxide
  • Solar water heating systems
  • Photo developing equipment                                     Ÿ     
  • Chemical injectors          
  • Boilers
  • Portable dialysis machine  
  • Medical equipment requiring water connection
  • Fire Sprinkler systems

The Oregon Health Authority and the City of Aurora work to maintain a safe drinking water system.  State law requires all public water systems to maintain a cross connection monitoring program.  This requires that property owners with cross connection backflow valves have the unit tested annually with the inspection report maintained by the city and reported to the state agency.  The city staff will work to maintain a 100% reporting standard each year.
