To be included on Livermore Municipal Water’s approved backflow testers directory, each tester must turn in their City of Livermore business license, backflow tester wall certificate, wallet card, and test kit calibration certificates annually. Testers are required to have their test gauge equipment calibrated annually and submit proof of calibration. Approved testers must be certified by the American Water Works Association (AWWA), the Northern California Backflow Prevention Association (NCBPA), or a similar certification program that is approved by Livermore Municipal Water.
