CCTV Drain Surveys, also known as Closed Circuit Television Drain Surveys, are an effective method of inspecting the inside of drains and sewer systems. This technique uses a small camera that is inserted into the pipe to inspect the inside of the pipe and identify any issues or blockages. In this article, we will discuss the process of CCTV Drain Surveys, including the types of issues that can be detected and the benefits of regular inspections.

The Process of CCTV Drain Surveys

The process of CCTV Drain Surveys typically involves the following steps:

1. Access: The first step is to gain access to the pipes that need to be inspected. This can be done through manholes, clean-out access points, or other openings in the pipe system.
2. Inspection: Once access is gained, a CCTV camera is inserted into the pipe. The camera is connected to a monitor that is used to view the inside of the pipe in real-time. The camera is typically mounted on a crawler or a pushrod, which allows it to move through the pipe and inspect its entire length.
3. Recording: The CCTV camera records the entire inspection, which allows the technician to review the footage later and identify any issues that may have been missed during the live inspection.
4. Analysis: After the inspection is complete, the footage is analyzed to identify any issues or blockages that may be present in the pipe. This analysis is typically done using specialized software that allows the technician to measure the pipe’s diameter, identify any cracks or breaks, and locate any blockages or other issues.
5. Reporting: After the analysis is complete, a report is generated that details the findings of the inspection. This report typically includes a map of the pipe system, a description of any issues that were identified, and recommendations for repairs or maintenance.
