What is specific about Al Mhmdya for hidden water leak detection

The centre of Al Mhmdya is at 21.6495, 39.1253, about 12.8 km from the centre of Jeddah, with an approximate radius of 2.9 km. The service-area circle on the map below is drawn from this point. Main roads in or near Al Mhmdya: Madinah Road, Al Nuzhah Street, Prince Sultan Road.

The centre of Al Mhmdya sits about 6 m above sea level (SRTM open elevation data). Al Mhmdya is about 2.4 km from the sea coast (OpenStreetMap).

Hidden water leaks in warehouses usually start small and stay out of sight. Under a concrete slab, behind a wall lining, or along an underground supply line, a slow leak can run for weeks before anyone sees the damp patch or the rising water bill. In a storage building, the first sign is often soft ground near a floor drain, a musty smell in a corner, or stock on pallets that feels cold and damp. By the time staff notice, the water has often spread under racking and across the floor, making the repair larger and more disruptive than it needed to be.

Al Mhmdya changes how we approach these checks. The centre sits at 21.6495, 39.1253, about 12.8 km from the centre of Jeddah, with an approximate radius of 2.9 km, so many warehouses here sit on the edge of the city where supply lines and storage tanks are spread across a larger site. The centre sits about 6 m above sea level, which means water is generally pumped up to storage rather than flowing down by gravity, so pressure changes and pump cycles matter when we trace a leak. The area is also about 2.4 km from the sea coast, which is close enough that salty, humid air can affect buried pipes, fittings and any exposed metalwork. Our survey starts with pressure and meter readings across the site, then moves to listening and thermal checks along the lines most likely to be affected by those conditions.

Before the visit, ask for the building layout, the location of any underground supply lines and drains, and the age and type of any water tanks on site. If a tank needs repair, ask about the internal coating: the cost of tank internal coating is SAR 25–65 per m², so the surface area of the tank will shape the final figure. Tell us when the leak was first suspected, whether the water bill has risen, and which areas of the warehouse are affected. Clear answers to these questions let the technician plan the right tools and reach the source faster.

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 hissing or trickling sound in the wall after the taps are off
• A damp patch that slowly grows on a wall or ceiling
• A water bill higher than usual with no change in use

The most common causes

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

How we choose the tool in Al Mhmdya

The steps in order

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

The written outputs

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.
