The purpose of a backflow prevention device is to keep unsafe drinking water from mixing with the potable water supply. A backflow prevention device is to be installed on all residential irrigation systems, fire sprinkler systems, commercial facilities where chemicals are used, boiler systems, and other systems where drinking water could become contaminated.
Thornton personnel test all backflow prevention devices annually, as required by the State of Colorado. This testing process helps Thornton ensure a safe drinking water supply for its residents.
For further information on backflow prevention devices, contact the Cross Connection Program Specialist by placing a service request, calling 720-977-6586, or emailing firstname.lastname@example.org.
