Pipe Tracing and Utility Mapping

Part of the process of water pipe leak detection is tracing the location of the pipe. Being able to trace pipe locations is a very important part of what we do. Not only do we need to be able to understand where pipes run if we are finding leaks on them, we also regularly carry out utility mapping exercises for our customers.

Trace Surveys trace pipes in four main ways:

Ground Penetrating Radar (GPR)

This works by sending radar pulses into the ground and monitoring the reflection from structures in the ground. This method is usually very effective for tracing larger diameter services and trench locations.

Thermal Imaging

The route of the pipe can often be seen with a thermal imaging camera when the fluid running through the pipe is able to influence the surface temperature of the ground above the pipe. This method is particularly helpful when we are tracing internal or external heating pipework.

Electronic Pipe Tracing

An electric pulse is introduced through the pipe wall or through a cable which is inserted through the pipe. The current creates a magnetic field and we trace that field at ground level.

Acoustic Pipe Tracing

We have devices that introduce noise through the water inside a pipe. The noise can then be traced at surface level using specialist listening device. This method is very helpful for tracing plastic pipes.
