Before we start: what we know about Al Jnadrya

The centre of Al Jnadrya is at 24.8192, 46.8528, about 21.4 km from the centre of Riyadh, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. The centre of Al Jnadrya sits about 586 m above sea level (SRTM open elevation data).

The nearest wadi channel is about 2 km from the centre of Al Jnadrya (OpenStreetMap). Main roads in or near Al Jnadrya: Al Janadriyah Road, Imam Abdullah bin Saud bin Abdulaziz Road.

Al Jnadrya is a quiet area of farms and rest houses about 21.4 km from the centre of Riyadh. Its centre sits at 24.8192, 46.8528, with an approximate radius of 1.2 km, so most properties here are spread out and reached by private access roads rather than dense streets. That spacing matters for leak work: a single supply line can run a long way between a well or tank and the buildings it feeds, so a technician needs to trace pipes across open ground rather than follow a short street run.

The centre of Al Jnadrya sits about 586 m above sea level, which means the land is not flat in the way a coastal area is. Water pressure in pipes at different heights can vary, and a leak lower on a slope may show up as a damp patch or a sudden drop in flow at a different point than expected. Ground that falls toward the valley also means soil can stay wet longer after rain. The nearest wadi channel lies about 2 km from the centre of Al Jnadrya, and seasonal runoff from it can saturate the ground near low-lying pipework, which is why a hidden leak here is often found by checking soil moisture and pressure readings together rather than by surface signs alone.

For tanks, the practical effect is a clear pricing reference. Internal coating is charged at SAR 25–70 per m², so the exact figure depends on the tank's size and the condition of its surface. Owners who ask for a leak check before coating avoid paying to seal a tank that is only leaking through a fitting or a cracked joint, which is a common and avoidable expense. Other mistakes owners avoid here include waiting for a visible puddle before calling for help, which in open terrain may mean the leak has run for a long time; assuming a meter reading that climbs slowly is normal; and repairing one damp spot without checking the pipe run that feeds it. A proper survey covers the whole supply path, so the repair stays focused and the water stays where it belongs.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

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

The most common causes

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

Tools and methods, and when we use them

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.
