Why hidden water leak detection differs in Al Farwq

The centre of Al Farwq is at 21.4513, 39.2681, about 14.2 km from the centre of Jeddah, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. The centre of Al Farwq sits about 43 m above sea level (SRTM open elevation data).

Al Farwq is about 9.1 km from the sea coast (OpenStreetMap). Main roads in or near Al Farwq: Jeddah–Makkah Expressway, Al Falah Road, Al Haramain Road.

Hidden water leaks in warehouses usually start small and stay out of sight. A slow drip under a concrete slab, a split pipe behind racking, or a seam in a buried line can run for weeks before anyone sees damp patches, mould, or a sudden jump in the water bill. In a large storage building, the first sign is often a soft floor, a musty smell near the back wall, or stock that has picked up moisture. By the time the problem reaches the surface, the damage to pallets, packaging, and flooring has often already spread, which is why early, methodical detection matters more than a quick visual check.

Al Farwq sits at about 43 metres above sea level, roughly 9.1 km inland from the coast, and its centre lies around 14.2 km from central Jeddah, within a radius of about 1.2 km. That inland position means warehouses here are typically serviced by a mix of trunk supply and on-site storage tanks rather than close-to-the-shore conditions, so leak checks should cover both the supply lines and the storage side. The moderate elevation affects pressure in the lines, so a pressure drop or irregular flow should be read alongside meter data rather than dismissed as normal variation. Because the site is a fair distance from the city centre, the crew will need to plan access and equipment for the full visit, and a clear survey of the building layout should be ready before they arrive.

Before the visit, ask the provider how they will locate the leak without opening up more of the floor than necessary, and what method they use for buried and slab-run pipes. Ask whether they will check the storage tanks, and if the tanks need recoating, ask for a written quote based on the coated area, which is typically priced at SAR 25–65 per m² for internal tank coating. Confirm who will handle the repair, whether the cost of opening and reinstating the floor is included, and how the findings will be recorded so you have a clear report for your insurer and your maintenance team. Finally, ask what the building needs to be like on the day, including whether stock must be moved and whether water supply will need to be shut off.

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

When do you need hidden water leak detection?

The following signs are worth checking before they grow:

• A water bill higher than usual with no change in use
• The meter keeps turning with every tap closed
• A hissing or trickling sound in the wall after the taps are off

Where the problem usually comes from

• A common cause: a cracked pipe under floor tiles.
• A corroded joint inside a wall — we check this before anything else.
• A common cause: a hot line that expands and contracts with use.

Tools we use in Al Farwq

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.

What we advise against

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

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.
