What is specific about Al Thghr for hidden water leak detection

The centre of Al Thghr is at 21.4771, 39.2344, about 9.7 km from the centre of Jeddah, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. Main roads in or near Al Thghr: Prince Majed Road, Prince Majed - Al Sabeen, Prince Majed - Al Sabeen.

The centre of Al Thghr sits about 31 m above sea level (SRTM open elevation data). Al Thghr is about 5.3 km from the sea coast (OpenStreetMap).

Hidden water leaks in clinics most often start in places nobody sees: behind wall tiles in treatment rooms, under sinks that are used many times a day, along pipe runs that feed sterilisation and dialysis equipment, and in the concealed sections of rooftop or ground-level storage tanks. Because clinics run long hours with constant water demand, a slow leak can go unnoticed for weeks while it damages plaster, flooring and nearby electrical fittings. Early signs include a sudden drop in water pressure, damp patches on walls at low level, a musty smell in corridors, and a water meter that keeps turning when all taps are closed.

Al Thghr, centred at 21.4771, 39.2344 and covering an area of about 1.2 km around that point, sits roughly 9.7 km from the centre of Jeddah. Its ground lies about 31 m above sea level, and the coast is about 5.3 km away. These facts shape the approach. Clinics here are often in buildings where the water supply and storage arrangement varies from one block to the next, so the survey starts by mapping the full route from the storage tank to each outlet. The distance to the sea and the warm coastal air mean that moisture and salt can speed up corrosion in older metal fittings, so inspectors pay close attention to joints, valves and any exposed sections that have aged. For tanks, the internal coating is a key cost factor; typical internal coating work is priced at SAR 25–65 per m², and the surface area of the tank determines the final figure.

Before the visit, ask the provider to confirm exactly which areas the survey will cover, including storage tanks, rooftop lines and any concealed runs behind treatment rooms. Ask whether they will use pressure tests and listening equipment, and whether they will work around your opening hours so patient care is not disrupted. Request a written scope that lists the surface area of any tank to be coated and the rate that applies, so the quote can be checked against the SAR 25–65 per m² range. Finally, ask how they will record their findings, what photographs or readings you will receive, and how repairs will be sequenced to keep your clinic running safely.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

When do you need hidden water leak detection?

These are the signs most often linked to hidden water leak detection:

• 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 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 cracked pipe under floor tiles.
• A common cause: a corroded joint inside a wall.

Tools and methods, and when we use them

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.

Mistakes that cost more

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