Backflow & Cross Connection Control Program

Overview

A cross connection is any point in a water distribution system where contaminants may come into contact with potable water. During a backflow event, these contaminants can be drawn or pushed back into the potable water system. 

A backflow prevention device is installed at points where a cross-connection is likely and prevents contaminated water from entering the potable water distribution systems.

The Colorado Primary Drinking Water Regulations provide the authority for local cross-connection control programs. These regulations mandate public water suppliers to require installation of containment assemblies on all service connections that pose a potential health hazard to the public drinking water system.

State and local plumbing codes regulate backflow prevention requirements within buildings. In Colorado, state and local plumbing codes are based on national standards, such as the Uniform Plumbing Code and the International Plumbing Code.

The regulations and codes require all backflow prevention assemblies to be inspected and tested annually. This is to ensure that they are functioning properly.

2023 Program Updates

In 2022 the City of Arvada implemented a schedule change for the testing and certifications of all backflow prevention assemblies. All assemblies must now be tested by a certified tester by July 31st annually.

Beginning in 2023, a fee schedule for non-compliant customers has been added. Please note a letter will be sent at the beginning of each year with your device information. Please do not throw this away, as your testing company may request this information.

Thank you for your assistance in helping ensure that the City of Arvada continues to provide clean, safe water to everyone in the community.
