For companies in Al Jwhra, Jeddah, the most common hidden water problem is a slow leak that never shows up as a visible puddle. Office and warehouse buildings often lose water through concealed pipework behind walls, under slabs or inside service ducts, and the first sign is usually a rise in the water meter reading or a damp patch that appears weeks later. Because the loss is gradual, staff may not notice until the bill or the wall finish shows the damage. Detection in these buildings therefore starts with checking the meter and the pipe runs before any opening of finishes.

The local setting shapes how this work is approached. The centre of Al Jwhra sits at 21.4370, 39.2535, roughly 14.5 km from the centre of Jeddah, with an approximate radius of 1.2 km, so most sites are a reasonable drive from the city core and crews should plan for that on arrival. The centre of the area is about 31 m above sea level, and it lies about 7.1 km from the sea coast. Those facts matter for a company's water system because it affects how pressure is delivered to upper floors and how storage tanks are fed and monitored. Any tank inspection should consider the internal coating as well, which is priced at SAR 25–65 per m², so the scope of coating work should be confirmed in writing before it starts.

Before the visit, ask the provider which parts of the building they will test, and whether they will use the meter reading and the pipe layout to narrow the search before opening any walls. Ask how they will record the findings, what the access arrangements are for a working site, and whether they will check the storage tanks and their coating at the same time. Confirm the location of the site against the Al Jwhra centre coordinates so the crew can plan travel. A clear list of these points helps the company keep disruption low and the repair focused on the actual leak.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

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

• The meter keeps turning with every tap closed
• A water bill higher than usual with no change in use
• A damp patch that slowly grows on a wall or ceiling

The most common causes

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

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.
