Why hidden water leak detection differs in Al Ajawyd

The centre of Al Ajawyd is at 21.4033, 39.3096, about 21 km from the centre of Jeddah, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. The nearest wadi channel is about 1.9 km from the centre of Al Ajawyd (OpenStreetMap).

Al Ajawyd is about 12.3 km from the sea coast (OpenStreetMap). The centre of Al Ajawyd sits about 94 m above sea level (SRTM open elevation data).

Hidden water leaks in warehouses usually start where nobody looks every day: under concrete slabs, along buried supply lines, behind wall-mounted tanks, and at joints where pipes pass through floors. The first sign is often not a puddle but a rise in the water meter reading, a damp patch on a lower wall, or a floor that stays cool and dark in the same spot. In a large storage building, a small loss can run for weeks before staff notice it, and by then it may have soaked into the base layer under the floor.

Al Ajawyd sits at about 94 m above sea level, roughly 12.3 km inland from the coast, and its centre lies at 21.4033, 39.3096, about 21 km from the centre of Jeddah. The nearest wadi channel is about 1.9 km from the centre, so during the rare heavy rain, water moves across ground that is already dry and hard. This matters for detection because a warehouse here may have storm drainage that runs toward the wadi and buried lines that sit in ground which can shift after a downpour. A survey in Al Ajawyd should therefore check drainage routes and any low corners of the plot as well as the water lines inside the building, since a leak and a drainage fault can look alike from the surface.

Before the visit, ask the provider which method they will use, such as acoustic listening, thermal imaging or tracer gas, and whether they will test the tank and pipework separately. Ask how they will mark the affected area so your team can repair it without tearing up more floor than needed. If your warehouse has a water storage tank, ask about internal coating options and their cost per square metre, which for tank internal coating typically falls in the range of SAR 25–65 per m². Request a written report that lists each location checked, the readings taken and any repair recommended, so that you can compare the findings with your meter records over the following months.

For warehouses, work is phased around operations and stored goods.

Signs that call for hidden water leak detection

The following signs are worth checking before they grow:

• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off
• The meter keeps turning with every tap closed

Where the problem usually comes from

• A common cause: a hot line that expands and contracts with use.
• A common cause: a corroded joint inside a wall.
• A cracked pipe under floor tiles.

Tools and methods, and when we use them

How the work is done, step by step

1. Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
2. Line isolation: We close valves one line at a time to see which line loses pressure.
3. Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
4. Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
5. Documentation: Readings, photos and the likely position go into a written report.

Common mistakes we see

• Repainting the stain while the moisture keeps coming back
• Breaking tiles at random before the line is identified

What you receive

The written output: a technical report with the readings, the likely leak position and a confidence level. The report is numbered and can be checked with its verification code.
