Using a high-tech camera, it’s now easier to check whether your drain and sewers are working properly. In this guide, let’s discuss what’s all about a CCTV drain survey.

A CCTV drain survey is a modern technology for assessing the condition of drains and sewers using a remote-controlled CCTV. It produces high-quality images of the inside of your pipeline cheaper and faster. You can identify potential problems and put an action plan easily. As such, they can prevent small issues to stress you out into a big one.

How Does a CCTV Drain Survey Work?

The following equipment is needed to conduct a CCTV drainage survey:

  • Access rods to push the CCTV on the drainage system. They should be highly flexible for easier navigation around corners and tight turns.
  • Remote-operated crawlers for a quick visual of the sewer system. This is to properly prepare the path for the CCTV and rods. Crawlers have excellent mobility even in blocked drains.
  • Sonar survey units on standby. They can be used for acoustic profiling of filled pipes in case visual access isn’t possible.
  • Waterproof CCTVs (Closed Circuit Televisions) are state-of-the-art cameras that can operate in tight spaces and under the water. They are the main tools needed to get an accurate visual of your drains and sewers.

Here’s the process on how to conduct a CCTV drainage survey:

  • An engineer, pipeline specialist, or plumber will discuss the problems you’re having with your drains and sewers.
  • Once they establish that a drain survey is needed to resolve the issue, the process will start.
  • They will insert a waterproof CCTV on your drain system.
  • While navigating the CCTV, they will observe the visual feed from the camera to assess any blockage or damage. Common findings will be blockages, burst or collapsed pipes, pipe corrosion, infestation, and tree roots ingress on the system.
  • After the CCTV drainage survey, they will recommend a plan of action to resolve the problems on your drains and sewers.

In general, a CCTV drain survey allows you to address small issues on your drain and sewers before it gets serious. It saves you money, stress, time, and trouble.
