Backflow Prevention Program

Backflow Prevention Program

The Consolidated Mutual Water Company’s (Consolidated’s) backflow prevention program is required by the Colorado Department of Public Health and Environment (CDPHE) Regulation 11.39.  The program ensures consumers continue having access to safe drinking water. The Backflow Prevention Department helps protect the safe drinking water from contamination or pollution caused by backflow from an owner’s internal plumbing system or alternative water sources by surveying all applicable accounts for existing or potential hazards.

Consolidated’s Backflow Prevention Department enforces and monitors the installation and testing of required backflow prevention assemblies, which must meet the lead-free and USC approval standards (approved model lists available upon request). If the installation of a backflow prevention assembly is required, the Stockholder must schedule an authorized Consolidated representative to witness the initial testing of the new assembly. The Stockholder is also responsible for having backflow prevention assemblies tested every year after installation.

Consolidated must be notified within 24hrs of failed testing, and the backflow prevention assembly is required to be repaired or replaced within ten days. Be advised that Consolidated may require certified inspections at more frequent intervals (e.g., change of business use or significant changes in the use of water).

Contractors – be advised adequate backflow prevention is required during construction or any projects utilizing Consolidated water. Please contact the Consolidated Backflow Prevention Department directly for new construction and retrofit DOMESTIC or FIRE line backflow specifications.

Any person or company who violates this program or CDPHE regulations shall be subject to the termination of water service until the violation is properly corrected and inspected by an authorized representative of the Consolidated Backflow Prevention Department.
