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 a cargo van or a box truck; however, for easements or difficult-to-access locations, HUSA has portable CCTV systems mounted on easement machines or all-terrain, amphibious vehicles.
Most CCTV inspections are conducted in accordance with the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP). All HUSA CCTV operators and data analysts are PACP certified by HUSA’s in-house certified PACP trainer.
