At filling and how often thereafter must emergency potable water tanks be bacteriologically analysed?

Explanation:
Regular monitoring of emergency potable water tanks for bacteriological safety is required. When the tank is filled, a bacteriological analysis is performed to confirm there is no contamination. After filling, the tanks must be tested at monthly intervals to ensure the water remains potable during storage and before use in an emergency. Daily or weekly testing would be impractical and quarterly testing could miss contamination for too long, while monthly testing provides a reliable cadence to detect issues before the water is needed. If a test shows contamination, corrective actions (such as disinfection and retesting) are taken to restore potability before use.
