Backflow Prevention Program

In adherence to Article 12 of the Colorado Department of Public Health and Environment’s Primary Drinking Water Regulations, the Backflow Prevention and Cross-Connection Control Program protects the public water system from cross-connection contamination by requiring customers to:

  • Install containment devices on water services feeding specific types of properties, such as commercial buildings and multi-residential units.
  • Test containment devices after initial installation and annually thereafter to make sure they are functioning properly.
