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.


  • Submit completed test reports to Cherry Creek Valley Water & Sanitation District (CCVW&SD) by                                                                              Email: ccvwbackflows@qwestoffice.net (only backflow inquiries please)  Fax: 303-755-4908 or                                                                           Mail: 2325 S Wabash St, Denver, CO 80231
