Hazard Assessments

In addition to the annual backflow prevention assembly inspections & testing, the water customer is responsible for completing Hazard Assessment of their site(s) as required by the CA State Water Resources Control Board (SWRCB) Cross Connection Control Policy Handbook (CCCPH) Article 2, Section 3.2.1 where it states: “All water services that are connected to a public drinking water system are to complete an initial assessment of their site.”  

In accordance with the City of Milpitas Code, Title VIII, Chapter 3, if the assessment finds that your BPA is inadequate for the hazard assessed, you will have 30 calendar days from the date of the signed assessment to protect your water service with the appropriate BPA as indicated in your signed assessment or to the highest level of backflow protection (RP). Altered or replaced BPA’s will require re-testing and submittal of test results via the online submission portal. A passing test of either the existing BPA, or the replaced BPA (if required by the findings of the hazard assessment) must be received no later than September 30, 2025. If more time is needed to test a replaced BPA, immediately notify the City. Failure to comply will require you to install the highest level of backflow protection (RP) or require your water service to be TERMINATED until the correction has been made.

Per the CCCPH, a Cross-Connection Control Specialist must review or conduct an Initial Hazard Assessment and make a written finding that identifies all hazards at the time of the assessment, the appropriate degree of hazards, and the backflow protection necessary to mitigate the hazard. If after the initial assessment there are any change to the account holder, change in operations, there is a backflow event, or at the request of the State Water Board and/or City, an immediate re-assessment is required. 

Note: The City does maintain a list of Qualified Cross-Connection Specialists which is available now! See the "Quick Links" below.
