Drain TRACING SurveysTracing and drain discovery
We offer a specialist service for surveying and tracing drainage channels using the latest technology and equipment. Using our skills and knowledge we can pinpoint issues prior to excavation.
The image below showing the sonde (or transmitter) placed inside the drain, pipe or sewer. It then travels in the direction required. As it moves, the transmitter sends a sonar pulse which can be located above ground using a reciever. The pulse single is sent in a circular or arch configuration, allowing the reciever to be adjusted so that the signal is weakest when directly above the transmitter.
UMS cameras have built-in sondes, allowing pipelines to be traced for up to 250 metres. We use these sondes to pinpoint defects seen in CCTV Surveys, prior to excavation. We're also able to locate dburied chambers, septic tanks and interceptor traps.
