Water Leak Detection & Pipe Locating in the UAE & GCC
Find the leak before you dig. We supply acoustic leak detectors, noise loggers, correlators and pipe locators from Sewerin for utilities, industrial sites and contractors.
Which leak detection tool do you need?
Leak finding works in stages: find the area, narrow the section, then pinpoint the spot. Each stage uses a different tool.
| Your situation | Start with | Why |
|---|---|---|
| Which district or zone is losing water? | Noise loggers | SePem loggers listen for abnormal noise in distribution pipes or valves during quiet periods and raise an alert. |
| Narrowing the leak along a pipe | Test rod or listening device | The AquaTest T10 has the amplifier built into the rod. The Stethophon 04 picks up structure-borne leak noise on pipes, valves and fittings. |
| A long pipe with only a few access points | Correlator system | The SeCorrPhon AC 200 combines prelocation, pinpointing and correlation in one system. |
| Pinpointing the exact spot at the surface | Electro-acoustic ground microphone system | The AQUAPHON A 200 uses sensitive piezo microphones and wireless communication to pinpoint leaks in underground supply pipes. |
| Knowing where the pipe runs before you excavate | Pipe and cable locator | UtiliTrac shows position, orientation and depth in 3D. The UT 9200 supports up to 100 frequencies with GNSS documentation. |
No single tool works on every pipe. Pipe material, depth, pressure and background noise all affect which method finds the leak fastest, so tell us the network details.

How a water leak survey is planned
A typical order of work for a distribution network or site pipework.
- Confirm the lossCompare supply and consumption figures to see whether water is being lost and roughly where.
- Narrow the areaPlace noise loggers on valves and fittings and listen overnight, when background noise is lowest.
- Prelocate the sectionUse a test rod, listening device or correlator to find the pipe section that holds the leak.
- Locate the pipeTrace the line with a pipe locator so you know its route and depth before digging.
- Pinpoint the spotUse ground microphones at the surface to mark the leak position.
- Record and repairDocument the position, repair the pipe and check that the noise or loss has gone.

Water leak detection FAQs
How do you find an underground water leak?
Usually in stages: loggers or a correlator find the area or pipe section, then listening devices and ground microphones pinpoint the exact spot before excavation.
What is a noise logger?
A small acoustic sensor fixed to a valve or fitting. It listens during quiet hours and flags abnormal noise that points to a leak.
What does a correlator do?
It compares the leak noise picked up at two points on a pipe to calculate where the leak lies between them. The SeCorrPhon AC 200 also does prelocation and pinpointing.
Why locate the pipe before digging?
A pipe and cable locator shows where the buried line runs and how deep it is, so you dig in the right place and avoid other utilities.
Do you also supply gas leak detectors?
Yes. Sewerin gas leak instruments such as the VARIOTEC 460 Tracergas and EX-TEC SNOOPER 4 are in the range.
Do you supply leak detection equipment across the GCC?
Yes. Daly Middle East supplies from Dubai to the UAE, Saudi Arabia, Oman, Qatar, Kuwait and Bahrain.
