Hidden water leak detection in Al Shmysy: the local context

The centre of Al Shmysy is at 24.6238, 46.7000, about 10.3 km from the centre of Riyadh, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. Main roads in or near Al Shmysy: King Fahd Road, Asir, Madinah Road.

The centre of Al Shmysy sits about 587 m above sea level (SRTM open elevation data). The nearest wadi channel is about 1.4 km from the centre of Al Shmysy (OpenStreetMap).

Hidden water leaks are the most common problem in homes and small buildings across Al Shmysy, and they are often found only after a damp patch, a rise in the water bill, or a faint smell appears on a wall or floor. Water can travel along pipes under slabs, through wall cavities, and behind tiles for weeks before anyone sees a stain. By the time the damage is visible, the leak has usually been running for some time, so the first priority is to locate it accurately and with as little disruption as possible.

The local setting shapes how we approach the job. The centre of Al Shmysy sits at 24.6238, 46.7000, about 10.3 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most properties here are set in a compact residential area rather than a dense urban core, and our technicians plan routes and equipment around that spread. The centre of Al Shmysy sits about 587 m above sea level, which is relevant when we check pressure and water flow in rooftop tanks and upper floors, since height affects how water moves through the system. The nearest wadi channel is about 1.4 km from the centre of Al Shmysy, which means that in wet weather ground moisture and seasonal run-off can sometimes mimic a leak, so we take readings on dry ground where we can and compare them against the pipework layout before we open anything.

Before the visit, it helps to have a few details ready so the technician can plan properly. Tell us the property type, how many floors it has, where the water tank is located, and when you first noticed the problem, along with any change in your monthly water bill. Ask whether the inspection uses non-invasive listening and pressure testing first, and whether any opening of walls or floors would be needed and how it would be made good afterwards. If the water tank has a coating that is wearing away, ask for the internal coating cost in the range of SAR 25–70 per m², so you know what that work would cost before you agree to anything.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

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

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 corroded joint inside a wall.

Tools we use in Al Shmysy

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.
