CCTV Sewer Inspection in Action
December 20, 2017Check out a CCTV Sewer Inspection in action: see how the technology was used to travel down a storm drain in search of a blockage.
Sewer inspection technology forms the backbone of a Sewer Safety Inspection (SSI) program. It’s used to monitor the performance of newly installed pipes and watermains, investigate unexplained flow conditions, locate blockages and inspect leak areas.
CCTV equipment is leveraged to investigate sewers, maintenance holes, chambers and other underground features from the surface. A CCTV camera travels along the sewer mains and provides video footage for inspection. It can determine the alignment of the main sewer and locations of lateral connections while side launching capabilities can determine the alignment of the lateral connections. A sonde can be used to map sewer alignment on the surface using electromagnetic designating equipment.
Pole camera equipment can be utilized to investigate sewers, maintenance holes, chambers and other underground features from the surface. The pole cameras are to be inserted from the surface with zoom lenses. Photographs are taken to assist in the investigation of underground features. This technology can inspect chamber configurations, pipe alignments and the presence of utilities can be inspected using this technology. Cameras are to be fitted with automatic compensation for low light conditions typically found in subsurface investigations.
The alignment of non-toneable sewers can be verified by pushing a sonde through the pipe. This is then mapped on the surface using electromagnetic designating equipment. Chamber depths, pipe configuration and the presence of debris may influence the effectiveness of this technique.

Cross bores can remain harmless and undetected for years, causing little to no disruption. However, potential dangers arise when a sewer backs up and needs to be unblocked. On rare occasions, a natural gas line has been punctured, causing gas…
