Help Protect CFU's High Quality Water

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.

CFU has contracted with Aqua Backflow to help manage this program. We appreciate your cooperation with Aqua Backflow regarding requests for information or when you receive a mailed survey.

Your licensed or certified backflow tester will enter your test results through the Aqua Backflow website TrackMyBackflow.com. You can also view your submission status on this site under the resources tab.
