Closed Circuit Television (CCTV) inspection systems have transformed the way professionals evaluate underground sewer infrastructure. These powerful no-dig solutions allow technicians to thoroughly assess the internal condition of pipelines, storm drains, and sewer mains — all without costly excavation or disruption to the surrounding environment.
Using CCTV technology, operators can accomplish critical tasks including:
CCTV inspection eliminates the uncertainty of traditional pipe assessments, delivering fast, precise, and cost-effective examination of drains, sewers, and other underground pipelines. It has become the preferred approach for municipalities, property developers, oil and gas companies, and homeowners alike.
How Do CCTV Cameras for Sewer Inspections Work?
These advanced instruments capture high-resolution images and video, all backed by intuitive software designed for seamless operation. Packed with smart features, CCTV inspection cameras help operators boost productivity, safeguard assets, and maintain the highest standards of safety and quality. Each CCTV camera connects directly to a computer system, feeding real-time data and imagery back to the operator — with all footage stored for convenient review at a later date.
Remote Visual Inspection Equipment
CCTV cameras come equipped with remote visual inspection tools available in a wide array of configurations, each tailored with distinct capabilities to handle the demanding conditions of various inspection environments.
Tractor Mounted CCTV Cameras
Tractor-mounted CCTV units are designed for inspecting sewers, maintenance holes, chambers, and other underground features from the surface. A motorized camera crawler travels through the sewer main, capturing detailed video footage along the way. This setup can assess the alignment of the main sewer line and identify lateral connection locations. Additionally, side-launching capabilities enable the camera to evaluate the condition and alignment of lateral connections branching off the main line.
A sonde transmitter can also be used to map sewer alignment at the surface through electromagnetic designating equipment — providing a comprehensive picture of the underground layout.
Push Cameras & Electromagnetic Sounding
Push cameras are perfectly suited for both commercial and residential sewer lateral projects. These compact units can be inserted at a clean-out point and guided through the pipe to locate blockages or identify condition issues. Equipped with a built-in electromagnetic sonde, the camera allows the horizontal alignment of the sewer to be verified and marked at the surface — including the precise location of any area of concern.
This technology is essential for confirming blockages in service lateral pipes and ruling out cross bore obstructions before any mechanical augering takes place.
Other Sewer Inspection Systems
Beyond standard CCTV crawlers and push cameras, professionals rely on a range of specialized equipment to get the job done right. Common sewer inspection tools include:
Investing in quality CCTV sewer inspection technology ensures accurate diagnostics, reduces repair costs, and minimizes disruption to properties and infrastructure. Whether for residential lateral checks or large-scale municipal assessments, the right camera system makes all the difference.
