• Pipeline Inspection, Maintenance, Repair and Rehabilitation


The purpose of Closed Circuit Television Inspection (CCTV) is to determine:

  • Structural condition
  • Location of O&M and structural defects
  • Evidence of inflow & infiltration (I/I)
  • Identify size and material of construction
  • Locate service laterals
  • Locate obstructions, such as roots, grease, debris and cross-bores

CCTV inspection generally consists of a remotely operated camera, mounted on a self-propelled robotic crawler that is connected to a video monitor at the surface. These systems are contained within our TV Truck; however, for easements or difficult-to-access locations, Pipeline Management has portable CCTV systems mounted on easement machines that make access to these difficult locations feasible. All of our CCTV inspections are conducted in accordance with the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP). All Pipeline Management CCTV operators and data analysts are PACP certified by and have been certified by a registered PACP trainer.

Typically, CCTV inspections are done after cleaning, but that is not always the case. Pipeline Management has the capability to CCTV inspect pipe diameter 6″ up to over 100″. For larger diameters, Pipeline Management uses its own manufactured walking cart if the pipe cannot be tractored. If the flow of the water is too fast or too high, Pipeline Management has the flexibility to use a pontoon CCTV system to float the pipe to complete the CCTV inspection.

After the CCTV inspection is completed in the field, the videos are then sent into our office where every video is checked for correctness and analyzed to make sure each individual client gets exactly what is expected per the project scope of work. Pipeline Management also can put together a management asset and rehabilitation plan based on the CCTV videos. This is another way that Pipeline Management separates itself as an industry leader.
