Sewerin Leakage Detection
We were contacted by a customer who advised that she thought she had a burst water pipe in her garden. I attended to evaluate the leak and feed back the findings to the office.
Upon arrival it looked like a potential leak on the water service, but to confirm that it was mains water I took a sample of the water and checked it for chlorine levels, which then confirmed that it was in fact coming from the domestic supply pipe. Although the customer was not pulling any water through to the property there
was a definite noise on her pipework, again this confirmed that there was a leak.
The next step was to locate and mark up the line of the water service and other utilities which was carried out using the cat and genny. I returned the following morning with the leakage detection kit and correlated the service pipe and located the burst 1.9 meters from the internal stop tap which meant that the burst was just on the outside wall of the property. The leak location was then marked accordingly.
The four black dots just above the centre of the screen are an indication as to how accurate the leak measurement is likely to be. The two bold numbers opposite blue 1 and orange 2 are the distance from the two correlators to the leak
point. The graph on the bottom left show the peak noises that the correlators are picking up, with largest reading shown inside the red box. The box on the bottom right shows the length of pipe being correlated and the leak location is highlighted by a red box.
The team then attended and carried out the excavation work against the foundations of the property, located the burst on the service pipe which was actually two holes and carried out a repair.
The job was then backfilled, spoil removed and slabs re-laid to the customers satisfaction. A final clean up and a few bags of fresh gravel and the job was complete.
