Hidden water leak detection in Al Hrazat: the local context

The centre of Al Hrazat is at 21.4924, 39.3664, about 20.8 km from the centre of Jeddah, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. The centre of Al Hrazat sits about 125 m above sea level (SRTM open elevation data).

Al Hrazat is about 18.8 km from the sea coast (OpenStreetMap). The nearest wadi channel is about 2.4 km from the centre of Al Hrazat (OpenStreetMap).

Al Hrazat sits at coordinates 21.4924, 39.3664, roughly 20.8 km from the centre of Jeddah, and its built-up core spans an approximate radius of 1.2 km. That means clinics here are set somewhat apart from the dense city grid, so a leak in a building's water system is less likely to be noticed quickly by neighbours or by the public utility. For a clinic that depends on steady water for sterilisation, handwashing and treatment rooms, the practical effect is that owners should not wait for a visible puddle or a sudden drop in pressure before arranging a survey. Our hidden leak detection work starts from the assumption that the building itself is the first place to look.

The centre of Al Hrazat lies at about 125 m above sea level, and it is roughly 18.8 km from the coast. Elevation matters for pressure: water pumped to upper floors and rooftop tanks works against gravity, so pressure changes and pump cycling can mask a slow loss or make it harder to interpret. Distance from the sea means the area is inland rather than exposed to the coastal air and salt, but it does not remove the need for regular checks. Because the nearest wadi channel is about 2.4 km from the centre, storm runoff and soil movement in the surrounding ground are worth considering when a survey is planned. Our technicians account for these conditions by reading pressure patterns across floors and by checking pipe runs that sit close to the ground.

Clinic owners in Al Hrazat often make the same few mistakes. Many wait for damp walls, staining or a higher water bill before calling anyone, which lets a hidden leak spread into ceilings and wall cavities. Others treat a tank problem as a simple patch, overlooking that internal tank coating is priced at SAR 25–65 per m², so the true cost depends on the surface area and the condition of the existing lining, and a rushed repair can cost more than a proper assessment. Some owners also rely on a single reading of the meter and assume the system is sound. We recommend repeated checks over several days, a written record of what was found, and a clear decision on coating or repair before any work begins.

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

Signs that call for hidden water leak detection

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

• 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.

How we choose the tool in Al Hrazat

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.

Questions from Al Hrazat

What we advise against

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

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.
