California requires that backflow prevention assemblies be installed on all hazardous cross-connections in an effort to keep our water supply safe. These assemblies must be tested and certified every year to ensure that they are working properly. The Joshua Basin Water District has partnered with Backflow Solutions, Inc. (BSI Online) to assist in administering the backflow program in our community.

Its important that we have your current mailing address in our system. You may receive letters from BSI alerting you as to when it is time to schedule a certified Backflow tester to test your device. You may also receive an email from Joshua Basin Water District as a way to reach you. 

You are responsible for hiring a licensed backflow tester to perform the annual test and certification of the backflow assembly(s) listed on your letter(s) and email(s). Please provide the CCN listed in the top right corner of this letter to your backflow tester, as they will need this number to properly file your backflow test reports via BSI Online. You may also use this CCN at www.bsionline.com to verify when your backflow test has been filed, locate a list of testers in your area, or to simply learn more about backflow. Please contact BSI via e-mail (support@backflow.com) or phone (888-966-6050) if you have any questions. Thank you for your cooperation and for helping to protect our water resources.

If out of compliance after all communication methods have been exhausted, we may be forced to provide a shut-off tag on your property to issue a final warning to have your device tested and updated into BSI's system. The certified tester will complete the certification on your behalf.
