CCTV Sewer Pipe Inspection Technology

Sewer camera technologies form the backbone of sewer condition assessments and sewer safety inspections. They are used to monitor the performance of newly installed pipes, investigate unexplained flow conditions, locate blockages, cracks and deformations, as well as for detecting leak areas.

multiVIEW employs Closed Circuit Television Video (CCTV) systems that offer various no-dig methods for analyzing the physical condition of sewer lines and storm drains such as:

  • detect and measure internal corrosion pits on pipelines
  • obtain visual data on the locations of leaks
  • identify other features such as valves, T-junctions, and elbows
  • understand causes of unexplained flow restrictions and their locations
  • pinpoint changes in pipe material

CCTV takes the guesswork out of pipe inspections, enabling quick, accurate, and cost-effective examination of drains, sewers, and other pipelines without damage to infrastructure. It’s the method of choice for pipeline inspection across various industries, including municipalities, property developers, oil and gas companies, and homeowners.

How do CCTV Cameras for Sewer Inspections work?

These instruments capture high-quality data-rich images and video and are supported by user-friendly software with a host of intuitive features to boost productivity, protect assets and help ensure safety and quality. The CCTV camera is connected to a computer and it feeds real-time data and images back to the operator with information stored for referencing at a later date.

Remote visual inspection equipment

CCTV cameras are equipped with remote visual inspection tools that come in a wide variety of configurations with different capabilities to meet the rigorous demands of inspection environments.

Tractor Mounted CCTV Cameras:

Tractor Mounted CCTV equipment is leveraged to investigate sewers, maintenance holes, chambers, and other underground features from the surface. A CCTV camera travels along with 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.

Push Cameras & Electromagnetic Sonding:

Push Cameras are ideal for commercial and residential sewer lateral projects. Cameras can be inserted at a clean-out easily and pushed through to identify a blockage or condition issue.  Because the camera is equipped with an electromagnetic sonde, the horizontal alignment of the sewer can be easily verified and marked on the ground surface, including the location of any concerned area.  Using this technology to identify blockages in service lateral pipes is necessary to rule out a cross bore obstruction before mechanical augering.

Other Sewer Inspection Systems:

multiVIEW utilizes a variety of equipment for sewer inspections, including:

  • Robotic Tilt & Pan Systems
  • Lateral Launch Cameras
  • Push Cameras
  • Sewer Flushing Equipment

Traffic pylons are arranged around the truck to ensure worker safety. Two field technician have managed to open a sewer manhole and are performing a CCTV Sewer inspection as one technician is operating the feed cable to the CCTV camera unit, while the other is operating the remote control system that enables the operator the control the direction of travel and capturing of photo and video footage to identify anomalies.
