Backflow Prevention

CFU's backflow prevention program is designed to protect our community's tap water from accidental contamination that can occur due to cross-connections. A cross-connection is any point where contaminants can "backflow" from the customer's point of use into the public water supply. Customer-owned lawn irrigation systems are the most common backflow hazard. To prevent lawn fertilizers and insecticides from entering the public water supply, all irrigation systems must be fitted with a backflow prevention assembly and inspected annually by a registered backflow testing firm.

See a list of local registered backflow testing companies.

Download backflow testing report form    This is the form a testing company should use to report results after testing the backflow prevention assembly on an irrigation system. Submission of this form to CFU documents that the homeowner or business has met the annual testing requirement.
