Cross Connection Control & Backflow Prevention Program

Park City Public Utilities works hard to ensure the safety of your drinking water. Our Cross Connection Control and Backflow Prevention Program plays a vital role in preventing contamination of drinking water caused by backflow through a metered connection.

Park City Public Utilities requires the submission of backflow test reports online. All testers are required to enter their certified test results here.

We will no longer accept paper copies of the test results.  Our goals with implementing this software include improved compliance, an increase in on-time backflow tests, and reduced administrative burden.  There is no charge for this program.

If you are a tester in the area, you can create an account by reaching out to with the information listed at: Backflow Tester Registration.

Park City requires all backflow tests to be submitted online, through the SwiftComply website. The following testers are registered with Park City’s SwiftComply system and registered with the State of Utah as of the time of publishing this page. 


If you are a tester who would like to be added (after completing registration) or removed from this list, please email

You may choose to have any State certified backflow tester complete your annual test. We recommend that you confirm that the tester you select is willing to submit your test results through SwiftComply. If you proceed with a certified tester and that tester does not submit your results through SwiftComply, you will have to have your device retested at your expense by a company willing to submit this information. The State certified list is available here.

Park City does not endorse any specific individual or company. It is recommended that you contact and receive quotes from several testers to ensure a fair price for the testing and any additional work to be done.  

Water distribution systems are designed so that water flows in one direction from the treatment plant or pumping facility to the customer. Backflow is an undesirable flow reversal of water and other substances into Park City's distribution system. Even though the water that reaches your home or business is safe, it can be contaminated by a backflow incident within your own piping that could also contaminate or otherwise degrade water quality in the water distribution system.

Federal and state laws require public water systems to protect their systems from cross connections and backflow. Park City Public Utilities takes every precaution to prevent cross connections by working closely with consumers, contractors, engineers, and regulators to ensure that all those who are required to comply with cross-connection control and backflow prevention meet the requirements.

Make sure you are in Park City's service area before submitting a test to SwiftComply using our Service Area Map.
