Cross Connection Control and Backflow Prevention Program

Cross Connection Control and Backflow Prevention Program

The Cross Connection Control Program protects the District's water system from possible contamination caused by a backflow event. These events happen when contamination is allowed to enter the drinking water system through a cross connection.

Commercial water users are required to:
  1. Install a backflow prevention device.
  2. Test upon installation and on an annual basis. It is the customer’s responsibility to have annual testing completed by a certified tester. A list of testers can be found here.
  3. Submit reports to the District’s Backflow Program Office by

    June 30th of each year.

Reports should be emailed to

Certified Backflow Testers


The South Adams County Water and Sanitation District’s Backflow Prevention Program, in conjunction with State Drinking Water Regulations and the CDPHE, require that all technicians have one of the following certifications, ASSE or ABPA.

Certified Testers List

The Certified Testers List is provided as a resource to assist the District’s water service customers in finding a contractor to complete testing and installations of backflow prevention devices, as needed. The District makes no representation regarding the abilities, performance, or quality of these resources, nor does the District assume or accept any responsibilities for the actions of testers or testers/installers named on the list.

We recommend that customers exercise judgment when contracting with any testers/installers, and to call several different testers for pricing and availability before setting an appointment for testing. Testing of devices usually vary from $50 to $150.
