Cross Connection Control

What is a Cross Connection Device?
A cross connection is any point in a water distribution system where chemical, biological or radiological contaminants may come into contact with potable (drinkable) water.

 During a back-flow event, these contaminants can be drawn or pushed back into the potable water system. A back-flow prevention assembly installed at every point of cross-connection prevents contaminated water from entering the potable water distribution system.

Do I need a Cross Connection Device?
Different jurisdictions mandate the minimum requirements for cross-connection control and back-flow prevention assemblies. The City of Rifle requires that all commercial users that handle food preparation, chemical mixing, refrigeration coolers, manufacturing and petroleum products and medical waste of any kind have a reduced pressure control device.

Any commercial building with Fire sprinkler systems must also have a double check assembly device installed on the system. Underground lawn irrigation systems also require a Cross Connection Control device.

What if I have a Cross Connection Device?
Each year Cross Connection Control devices must be tested and inspected with the report being sent to the City of Rifle. The inspection and testing insure that the devices are functioning properly so as to prevent contamination of the water system.

These tests are dictated by both sound water utility practice as well as the law. Each property owner is responsible for their own back-flow prevention device, including its annual inspection and repair.
