B.W. Watermain Testing Checklist

This watermain testing checklist guides site teams through validation of new or modified mains. Record project details, contractor information, site conditions, and the presence of a water authority validation officer. Perform and document swabbing, confirm backflow protection, and flush lines until clear. Conduct pressure testing on potable and recycled lines, capture start and finish times, and verify no pressure loss over the test period. Log gauge serial numbers and calibration dates, and document whether mains are held at pressure overnight with measured make up volumes. Assess results against defined volume change pass criteria. Conclude with auditor comments, photo records, and confirmation that corrective actions are completed.
