What Is Underground Water Leak Detection?
Underground water leak detection is the process of locating a leak on a buried pipe without digging up your property to find it. The most common culprit is the private supply pipe, the section that runs from the boundary stop tap or water meter, across your land, and into your home. Because that pipe is usually buried under driveways, gardens, patios or concrete, a leak can run undetected for months.
In most cases the private supply pipe is the homeowner’s responsibility, not the water company’s, so when it leaks, the cost of finding and repairing it falls to you, and the wasted water can show up as a sharp, unexplained rise in your bill. The earlier the leak is pinpointed, the less water is lost and the smaller the excavation needed to put it right.
We trace the line of the pipe and isolate the exact point of failure before anything is opened up, so any repair is targeted rather than guesswork. Below are the signs that often point to a buried leak.
- An unexplained jump in your water bill or meter usage
- The water meter still ticking over when every tap is off
- Damp, soft or boggy patches on the lawn, driveway or path
- A drop in water pressure at the taps
- The sound of running water with nothing in use
How We Find Underground Leaks
Acoustic Detection
Pressurised water escaping from a buried pipe makes a distinctive noise. Using sensitive ground microphones, we listen along the line of the pipe to hear that escape through soil, tarmac and concrete, then narrow the leak down to a precise spot.
Tracer Gas
For quiet leaks or non-metallic pipes, we introduce a safe tracer gas into the pipe. The gas rises to the surface at the leak point, where it is picked up by a detector, ideal for pinpointing escapes under driveways and concrete that acoustic methods alone may miss.
Pressure Testing
Before pinpointing, we often pressure test the supply pipe to confirm a leak exists and gauge its severity. Isolating sections lets us prove whether the fault is on the supply run or elsewhere on the property, so the investigation stays focused.

Underground Water Leak Detection FAQs
In most cases the private supply pipe, the section running from the boundary stop tap into your home, is the homeowner’s responsibility, not the water company’s. That means finding and repairing a leak on it falls to you. We pinpoint the exact location so any repair is as small and targeted as possible.
A sharp, unexplained rise in your water bill is one of the most common signs of a buried leak. Water escaping from the supply pipe is still metered, so you pay for every litre lost. Detecting and fixing the leak quickly stops that waste and brings your usage back to normal.
Yes. Leaks under driveways, patios and concrete are exactly what non-destructive detection is designed for. Using acoustic listening, ground microphones and tracer gas, we locate the leak through hard surfaces and mark the precise spot, so any breaking out is kept to a minimum.
No, that is the whole point of our approach. We trace the pipe and isolate the leak before anything is opened up, so the only ground that gets disturbed is the small area directly above the fault. There is no need to excavate the length of the pipe to find it.
Same-week appointments are often available across Devon wherever possible. Because a buried leak keeps wasting water and money until it is found, we aim to get to you quickly, pinpoint the fault on the first visit and give you a clear report you can act on straight away.
