In adherence to Colorado's regulations, the Cross-Connection Control and Backflow Prevention Program protects the public water system from cross-connection contamination by requiring customers to:
What is backflow, cross-connection and back-siphonage?
They all mean the same thing - used water that has already left your water pipes and is reintroduced into your home\'s water system. Backflow is caused by a drop in water pressure (i.e., while fire fighters battle a blaze or while crews are repairing a water main). A Backflow Preventer is a mechanical device that acts as a check valve to prevent used water from re-entering and potentially contaminating your drinking water.
How do I prevent this from happening?
1. Install containment assemblies (also known as backflow prevention assemblies, dual check valves (residential) containment devices or backflow prevention devices) on the following water service lines:
¬ Residential property water service lines (dual check valves)
¬ Dedicated irrigation lines (testable devices that comply with the uniform building code)
o Test containment assemblies after initial installation and annually thereafter to make sure they are functioning properly.
o Submit completed test reports.
