How CCTV Sewer Inspections Work

CCTV stands for Closed-Circuit Television. CCTV sewer inspection is a modern and effective method for assessing the condition of underground sewer and drainage systems. The YouTube video discusses what it is, how it's performed, and what benefits it holds. This article reviews how these systems work and breaks it down for you.

Conducting an Inspection

There are specifically designed CCTV cameras for this job. They are attached to flexible, waterproof cables and are small while built to withstand the conditions in the sewer.

Plus, the cables are long enough to navigate through the sewer system. Next, it's time to find an entry point. This could be a sewer hole. The camera is inserted into the hole, and the inspection begins.

As the camera travels through the sewer pipe, it captures real-time video footage. This footage is transmitted to a monitor or recording device above ground, allowing the operator to see the interior of the sewer. The operator guides the camera through the sewer, controlling its movement to inspect different sections. The camera can move forward and backward and pan and tilt to capture a comprehensive view of the pipe's condition.

Based on this information, operators can formulate an action plan without needing to dig up pipes unnecessarily. CCTV sewer inspections are a non-invasive and cost-effective way to assess the condition of underground sewer systems.
