Qualified Testers and Cross-Connection Specialists

The City of Milpitas’ Cross-Connection Control Program maintains a list of Qualified Backflow Prevention Assembly Testers and Qualified Cross-Connection Specialists approved to perform required performance testing and hazard assessments on all backflow prevention assemblies and water services in our City’s service area. The City will only accept backflow test results (Testers) and hazard assessment reports (Specialists) from testers and specialists that are being maintained on our Qualified Lists. Testers and specialists must receive confirmation from the Cross-Connection Specialist of their status on the Qualified List prior to testing an assembly or performing a hazard assessment.  

How to Submit Backflow Performance Tests

Test reports are due to the City within 60 days from the City's first notice to the water customer. If an extension is required, the customer is responsible for contacting the Cross-Connection Specialist to explain the reason(s) for an extension, but approval is not guaranteed. 

Electronic Test Reports 

Required for all routine tests, repairs & re-tests of existing assemblies. 

Qualified testers and designated signatories must register and submit test reports online through the City's Backflow Prevention Assembly Test Entry Portal. Note: Written/Scanned Test Reports will NOT be accepted
