Why is CCTV advantageous in sewer inspections?

CCTV, or closed-circuit television, is particularly advantageous in sewer inspections primarily because it provides the capability to visually inspect the interior of pipes without the need for invasive methods. This technology allows operators to record and analyze the conditions of pipelines, enabling them to pinpoint and document areas of concern, such as cracks, blockages, or other defects.

By using cameras equipped with advanced imaging technology, inspectors can capture real-time footage or still images that illustrate the severity and location of issues within the sewer system. This documentation is crucial for maintenance planning, prioritizing repairs, and ensuring the overall integrity of the sewer infrastructure. Furthermore, the recorded footage can be reviewed later, helping in legal or maintenance decisions.

In contrast, while cleaning pipes, minimizing costs, or ease of operation may seem beneficial, they do not capture the primary aim of CCTV inspections, which is to assess and document the condition of the sewer lines accurately. Other methods may be cheaper or easier to use, but none offer the same detailed, visual assessment that CCTV provides.
