Backflow Services

 State of California regulations require all municipal water systems to implement a cross-connection control program. Cross-connections are the physical connection between the potable water system and where a containment hazard exists, such as irrigation systems, fire protections systems, and any other potential or actual hazard connected directly to the main water supply. “Backflow” is the reverse flow from the fixture/equipment back into the drinking water piping.  If improperly protected, if a backflow event were to occur, contaminates could flow back into the City water supply.

Consequently, it is necessary for the City of Upland to establish and maintain a cross-connection control program ensuring all containment devices are protected and tested annually.

To provide the best program possible, the City of Upland has partnered with Backflow Solutions, Inc. or BSI, the nation’s leading backflow data management firm, to help with this endeavor. BSI is fully devoted to helping public water systems with the development, implementation, and maintenance of cross-connection control programs.

As of 10/01/2017, BSI will be sending backflow assembly due and past due notifications on behalf of the City of Upland. Your contractor will be informed of the new program procedures as well, as they will now have to submit your test results online via BSI’s system, BSI Online. Please contact BSI via email (bsionline@backflow.com) or phone (800-414-4990) if you have any questions. You will still need to call your contractor to schedule your annual backflow assembly test.

The City of Upland is proud of the water they deliver to you every day. By working together and cooperating in this critical program, we can further protect our water resources.
