Backflow Devices and Testing

A backflow prevention device is designed to protect water supplies from contamination.  They are commonly used on lawn irrigation and fire sprinkler systems.  Many homes and businesses in the City of Cornelius have a backflow prevention device.  

We, your Water Department, protect the water entering your system.  However, it is the property owner's responsibility to protect the water on their property and in their home.  Oregon Administrative Rule 333-061-0070 states the premise owner shall assume responsibility for testing, maintenance, and repair of the installed approved backflow prevention assembly and that testing shall be done at least annually.  

If you need information on locating a certified tester or have any questions, you can call Public Works at 503-357-3011.  A list of certified testers and more detailed information about the design and use of backflow prevention devices is located below.
