Steps
Establish a hazard-based facility inventory identifying customer classes required to have containment devices
Conduct or commission on-site surveys, often performed by ASSE 5120-certified surveyors, to identify actual and potential cross-connections
Assign the required backflow assembly type per identified hazard and record the required assembly and testing frequency for each account
Track annual test compliance per account and issue notices for missed or failed tests
Periodically re-survey accounts, since facility use and hazard level can change over time and re-survey intervals vary by state primacy agency
Known gotchas
A survey identifying required device types is not enforcement by itself — the program must separately track actual installation and ongoing annual testing to remain compliant with state primacy requirements
Re-survey intervals are not standardized nationally; check the specific state drinking water program's requirement rather than assuming AWWA M14's general guidance is binding
Some states are expanding containment requirements to smaller/residential accounts that historically were exempt — don't assume a legacy inventory scope is still current
