Drain survey footage is the recorded video output from a CCTV inspection, typically provided as a digital file alongside the written survey report. The footage allows engineers, homeowners, insurers and other interested parties to review observed defects directly, with on-screen captions noting chainage distance, pipe diameter and key timestamps. Recording follows BS EN 13508-2 and the WRc Manual of Sewer Condition Classification, with each defect coded for service or structural grade. In Greater London, retained footage supports property purchases, insurance claims involving drainage-related subsidence and adoption assessments with Thames Water. The file is usually delivered on a USB drive or via secure download and may be archived for future comparison. Engineers carry out the survey and produce the footage in accordance with industry practice using calibrated equipment.
