Backflow/Cross-Connection Information

California State Health Code

Under Title 17 and Title 22 of the California State Health Code all Backflow Prevention Devices must be tested at least once annually to ensure proper operation. The Company will mail a test form to each Customer/Shareholder that has a Backflow Prevention Device. A copy of the test and any repairs made by a Certified Tester must be filed with the water company providing water to the company/owner of the device. The Company/Owner of the device is responsible for the cost of the testing and the cost of replacing the device should said device fail testing.

Bellflower-Somerset Mutual Water Company mails out approximately 90 test notices per year under the current Backflow Prevention Device program and assesses a $115.00 charge per year per device for the maintaining of this program.
