How often does a warehouse in Mdayn Al Fhd, Jeddah, lose water through a pipe nobody can see? For many property owners the first sign is a damp patch on a slab, a sudden rise in the water meter reading, or a floor that feels cool underfoot. Mdayn Al Fhd sits with its centre at 21.4598, 39.2377, about 11.5 km from the centre of Jeddah, and its approximate radius of 1.2 km places most industrial plots within a short drive of the main routes. Its centre sits about 24 m above sea level, and the district lies about 6.5 km from the sea coast. Those facts matter because the ground, the buried pipework and the storage tanks on a site all respond to the local setting, so a leak is rarely just a plumbing issue on its own.

The inspection starts with a walk through the warehouse and its yard to note where water is being used and where it is not. Technicians then compare meter readings against expected use, check the lines that run under floors and along external walls, and use detection equipment to pinpoint the likely position of any hidden leak before any opening is made. Storage tanks are checked for internal condition as well, and where a tank shows wear, the coating can be assessed and quoted at SAR 25–65 per m², with the exact figure depending on the surface area involved. The aim is to find the source of the loss first, so that repairs are limited to the section that needs them.

To make the visit efficient, gather the water bills for the last several months, the building plan or any drawings of the pipe layout, and the dates of any repairs or tank cleaning. Note where you have seen damp, staining or unusual sounds, and tell the technician which areas are in regular use and which are closed off. Clear access to the meter, the main valve and the tank room before the visit, and let staff know in advance so that stock and vehicles can be moved away from the suspected areas. With this information ready, the inspection can focus on the right places from the start.

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

Signs worth paying attention to

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

The most common causes

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

Tools we use in Mdayn Al Fhd

From the first visit to the report

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.
