Hidden water leak detection in Al Kwthr: the local context

The centre of Al Kwthr is at 21.4546, 39.9666, about 13.4 km from the centre of Makkah, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. The centre of Al Kwthr sits about 375 m above sea level (SRTM open elevation data).

Al Kwthr sits at 21.4546, 39.9666, roughly 13.4 km from the centre of Makkah, and its built-up area spans an approximate radius of 1.2 km. That distance from the city centre means many duplexes here are set in a quieter, more spread-out pattern, and our hidden water leak detection visits are planned around travel time and access rather than a single dense block. Crews arrive with the equipment needed for a full survey, so a property owner is not left waiting for a second trip for parts or tools.

The centre of Al Kwthr sits about 375 m above sea level, according to SRTM open elevation data. At this height, water pressure in rooftop tanks and the pipe runs that feed them can vary noticeably between the upper and lower floors of a duplex. We take readings at several points in the system rather than only at the meter, because a pressure drop that looks minor at one tap can point to a concealed leak further along the line. The nearest wadi channel is about 2.1 km from the centre of Al Kwthr, according to OpenStreetMap. Because the area sits near a seasonal drainage path, we check ground-level pipework and external walls for moisture and staining, since heavy rain can hide the signs of a slow leak in soil around foundations.

Owners often ask us about tank work, and the figure to know is that tank internal coating costs SAR 25–65 per m². When we inspect a tank, we first confirm whether the leak comes from the coating, a fitting, or a supply line, so that the owner pays for the repair that is actually needed. Common mistakes we help owners avoid include waiting for a visible puddle before calling for a survey, repairing the first wet patch without tracing where the water is coming from, and assuming a tank that holds water is sound. Another frequent error is ignoring a rise in the water bill, which is often the first clear sign of a hidden leak in a duplex.

In a duplex, the two floors often share lines, so tests are done floor by floor.

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

Tools we use in Al Kwthr

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.

Common mistakes we see

• Breaking tiles at random before the line is identified

What you get after the work

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.
