How Do CCTV Drain Surveys Work?
The process of conducting a CCTV drain survey involves several key steps:
Preparation: Technicians prepare the drain or sewer by cleaning it thoroughly, removing any debris or obstructions that could interfere with the camera's movement.
Camera Insertion: A specially designed CCTV camera is inserted into the drain or sewer through an access point, typically a manhole or inspection chamber.
Remote Operation: The camera is remotely operated and controlled by a trained technician who guides it through the drainage system. As it moves, the camera captures high-resolution images and videos of the interior.
Real-time Monitoring: The live footage is transmitted to a monitor, where the technician can view and analyze it in real-time. They look for signs of blockages, cracks, corrosion, tree root ingress, and other issues.
Documentation: The survey is documented with detailed reports, including findings, recommendations, and images or videos as evidence.
Analysis and Action: Based on the survey results, appropriate actions can be taken, such as cleaning, repairs, or maintenance.
