Backflow Prevention

Back-flow Prevention and Cross Control Program (BPCCC)

The Pueblo West Metropolitan District’s (PWMD) Utilities Department, is dedicated to the protection of its public drinking water supply. Per the Colorado Department of Public Health & Environment (CDPHE), the District’s Utility Department has established a Written BPCCC Program. Properly working backflow prevention assemblies keep our drinking water clean and safe. 

The installation and annual testing of backflow prevention assemblies is a state requirement to help protect water quality and public health. State Regulation 11.39 requires PWMD to maintain a BPCCC Program to track the inspection, installation and annual testing of backflow prevention assemblies on all hazardous cross-connection (potential points of contamination and backflow). 

These regulations apply to all Commercial or Industrial water system connections where an uncontrolled cross-connection has been identified. Site surveys may also be necessary to assess the potential hazards on your property.

Read Resolution 2019-071 from the Pueblo West Metro Board of Directors adopting a written backflow and cross-connection control system for Pueblo West Metro District.

A backflow prevention device protects the potable water system from contamination hazards. To prevent a backflow occurrence, it is required there be a mechanical backflow prevention device between the delivery point of mains and commercial or industrial businesses who are connected to the main water infrastructure systems. The Environmental Protection Agency (EPA) holds local water suppliers responsible for maintaining a certain amount of purity in potable water systems.

  1. Where is the backflow assembly required to be installed?
  2. Will my water service be interrupted during the test?
  3. How much does a backflow device cost?
  4. Who is responsible for paying for the device and testing?
  5. What happens if I do not comply?
  6. Once my device is tested, who mails/emails my completed test form each year?

The backflow assembly must be installed on the customer's service line after the meter set and before any branching of the line to accommodate any additional taps, faucets or hose connections. There also must be a 12" clearance area around the entire device.
