What Is A CCTV Drain Survey, And How It Works?

To keep the quality of the pipes in check, it is necessary to know what’s going inside them. The best appropriate way to do this is by using CCTV to check the condition. The techniques used for drain cleaning are used in rainwater pipes, industrial pipes, and ducting pipes.

Everything A CCTV Drain Survey Means?

A drain survey is depth surveillance of drain pipes, using cameras that are inserted into the tubes. The cameras send live recordings of the channels, which allows the engineer to know the correct condition of the pipes. The survey is a bit invasive; all required is the wire to be sent down the drain.

When Does It Require A Survey?

The survey helps to investigate the drains and sewer issues, like blockage, liquid flow rates, etc. The survey keeps the data safe without requiring operatives to check hazardous gutters for health manually. The survey system maintains the drains’ condition to avoid any future damage and pipe issues. The method is also allowed to create a design for contractors for further construction projects. London CCTV drain survey enables the contractors to inspect the condition of lines before handling the properties to clients.

Types Of Drainage Camera System

·       Robotic Crawler Camera Technique

The camera used by the specialists has a range to cover about 150mm to 200mm in diameter. The cameras possess inbuilt led lights that record high-resolution video from a distance. The cameras have the electronic motor fitted, and wheels which will be changed depending on the situation. The cameras usually hold arms, and a tilting camera feature, and zoom lenses. In this process, the canals get recorded, and feedback is given on time.

·       Push CCTV Camera System

This system is used for pipes with lesser diameter.

 The crawler technique cannot be used in lines with smaller diameters. In the push technique, the camera is attached to one end of the rod with which led lights are secured with a wheel. The cameras applicable here are called push rod cameras. The rod is then shoved inside the drains to record the live video of the lines.

·       How Does It Work?

The engineer will stick a minute camera at the end of a long, thin cable wound down a drain and into the pipes. The camera sends the signals to the operative’s computer, which helps them locate the issues and blockages. A London CCTV drains survey functions by sending the camera into the hole to capture live photos and videos to discover the reason for the jam. The putting of the camera in the drain can either happen mechanically or manually. As the camera goes inside, it will record the line if the operative sees any issue. The camera takes the blockage image to understand the problem, helping formulate a solution for the dilemma. The investigator will then take necessary actions to combat the situation.
