A specially designed van is normally used. A set up of camera mounted on 4 wheel drive small tractor (kind of sophisticated remote car for kids) is lowered through maintenance access hole for inspection.

The camera/lens usually has 360 view rotating and zooming capability.

Inspectors usually sit in the van and rate the live video. WinCan is well known software package/system for these kinds of CCTV inspections.

Data collected:

  • presence of sediment
  • roots invasion
  • presence of grease
  • presence of debris
  • presence of pipe cracks
  • joint displacment
  • condition of service connections

Issues:

  • Access hole size vs tractor/camera set up
  • Lifting of access hole lid
  • Pressure cleaning of pipes prior to inspection
  • Camera getting stuck
  • Physical cable rather than Wi-Fi video data transfer back to base station (in Van)
