At Total Drainage Services, CCTV drain surveys have completely revolutionised how we inspect and maintain underground pipe networks. These surveys utilise advanced camera technology to provide detailed insights into the condition of drainage systems without the need for disruptive excavation. By making your way through pipes and capturing high-definition footage, CCTV drain surveys allow professionals to identify blockages, leaks, structural defects, and other issues with precision. Discover the facts and details of CCTV drain surveys, explaining their step-by-step process, the benefits, and the invaluable roles they play in proactive maintenance and problem-solving for residential, commercial, and industrial properties. 

What Is a CCTV Drain Survey?

A CCTV drain survey is a sophisticated method used to inspect the condition of drainage systems without the need for innovative procedures like excavation. It involves inserting a specially designed camera into the pipes to capture high-definition footage of the interior. This technology allows professionals to identify and assess a number of issues like blockages, leaks, structural damage, and many other abnormalities that could affect the performance and flow of the drainage network. 

By providing detailed visual data in real-time, CCTV drain surveys enable accurate diagnosis of problems, facilitating timely and targeted maintenance or repairs to ensure good operation of residential, commercial, and industrial drainage services. 

Benefits Of CCTV Drain Surveys

CCTV drain surveys provide a number of key benefits that make them perfect for inspecting and maintaining drainage systems:

Precision and Accuracy – The high-definition cameras used in CCTV drain surveys capture clear and detailed footage of the inside of the pipes. This enables precise identification of issues such as blockages, leaks, cracks, and any other defects that may not be visible from above the ground. 

Non-Invasive Inspection – Unlike traditional methods that often require excavation or disruption to property, CCTV drain surveys are non-disruptive. It simply involves inserting a camera into the drain through access points, minimising disturbance to surroundings and reducing the need for restoration afterwards. 

Time Efficiency – The real-time monitoring capability of CCTV drain surveys allows operators to assess the condition of pipes accurately. This efficiency means that issues can be identified and addressed swiftly, preventing minor problems from increasing to costly repairs.


The Process Of CCTV Drain Surveys 

The process of CCTV drain surveys involves several key steps to effectively inspect the condition of drainage systems using CCTV drain surveys: 

Preparation – Before conducting the survey, preparations are made to access the drain. This includes identifying access points such as manholes or inspection chambers, and ensuring safety measures are put into place for operators. 

Inserting the Camera – A specially designed CCTV camera is inserted into the drain through an access point. The types of cameras used depend on the size and configuration of the pipes. There are many different types including pan-and-tilt cameras for larger pipes and pushrod cameras for smaller, more confined spaces. 

Navigation and Inspection – As the camera makes its way through the pipes, it captures high-definition video footage and pictures of the interior. Operators can control the camera remotely to adjust its direction and focus on specific areas of interest. This real-time monitoring allows for instant detection of any issues like blockages, leaks, cracks, or other issues. 

Recording and Documentation – Throughout the inspection, the CCTV camera records detailed footage of the condition of the pipes. This documentation is important for analysis and reporting purposes, providing clear evidence of any detected issues. 

Analysis and Reporting – After completing the inspection, we analyse the recorded footage and interpret the findings. This helps to assess the importance and severity of any issues discovered and determine the appropriate course of action, whether it involves repairs, maintenance or further investigation.
