Backflow Prevention and Cross-Connection Control Program

Fort Collins Utilities’ Backflow Prevention and Cross-Connection Control Program protects the public water supply from pollutants and contaminants that could, under certain circumstances, be drawn into the public water supply from private properties.

Commercial, Industrial, Domestic, Irrigation and Fire Lines
All commercial, industrial, domestic, irrigation and fire line services are required to have an approved backflow prevention assembly installed and tested annually.

Residential Properties
Requirements for multi- and single-family residences are assessed based on site hazards. Single-family residential properties are encouraged to hire a certified backflow prevention assembly tester to test their irrigation system every three years.

Auxiliary Water Supply or Dual Water Lines
All customers with an auxiliary water supply or dual water lines, such as a well or pond, also are required to install and maintain backflow prevention assemblies.

The Colorado Department of Public Health and Environment regulates drinking water quality and standards. The Colorado Primary Drinking Water Regulations (Section 11.39) outline Utilities' requirements for backflow prevention and cross-connection control.

In addition to installing an assembly, the water customer must have the assembly tested upon installation and annually thereafter by a certified tester. It’s important to remember that testing of existing and replacement backflow assemblies must be reported to BSI Online, and testing of new installation backflow assemblies should be submitted to Fort Collins Utilities by emailing Y3Jvc3MtY29ubmVjdGlvbkBmY2dvdi5jb20= or mailing to:
