The possibilities of an ROV at pipes…


Which pipes can be inspected?

This blog will focus on what is best to do when inspecting pipes, but first, of course, you need to know what pipes can be inspected! We’ll start with the different types of pipes:

  • Drinking water pipes
  • Drains (sewers)
  • Rain Water Drainage pipe

Why do these pipes need to be inspected?

This is actually quite simple. Pipes have to be inspected for various reasons, mainly from government legislation, Inspecting is laid down in laws for the purpose of checking structures under the road network. So it is about safety. The safety dimension in turn involves several dimensions:

  • Safety in terms of robustness of structures
  • Legally regulated
  • Safety in terms of hygiene

In addition, inspecting is also cost-effective; an inspection makes it very clear whether repairs are needed, and when they should be scheduled and by what means. Without inspections, this remains guesswork, with many unnecessary costs. Knowing where you stand is therefore essential.

How is the Rain Water Drainage pipe inspected?

HWA pipes are now inspected in a process-oriented way with many steps:

  • Putting baffles in the two well entrances to hold back the water
  • Draining the water between the baffles (to another well)
  • Sending an inspection robot into the pipe for inspection
  • Remove the baffles after the inspection

These are many steps that cost time, money and energy. That while these steps can be skipped via other inspection methods….

How can the inspection be done with underwater drones?

With an underwater drone (ROV), the drone can be lowered into the water in the pipe itself. This means that the pipe does not have to be drained and the above-mentioned steps can be skipped.

The pipes with rainwater are in principle reasonably clean, so this is no problem for an ROV with the 4K camera to make sharp images under water. If the water is murkier, then it is also possible to use sonar to take a good image of the pipe.

The difference below the line:

Despite the fact that we have a fixed fee, we are cheaper to inspect per meter. We can inspect much more in one day, namely up to three times as much as the current method.

With an underwater drone you can get through the water faster, and the pipes do not have to be dried. This saves time, and time is money. No additional parties are needed to perform an inspection either, just an operator and a drone.
