Backflow Prevention

 

Backflow Prevention Program and Cross-Connection Control

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.
