Before we start: what we know about Al Rwda

The centre of Al Rwda is at 24.7341, 46.7672, about 9.6 km from the centre of Riyadh, with an approximate radius of 2.9 km. The approximate area shown on the map is centred here. Main roads in or near Al Rwda: Eastern Ring Road, Khurais Road, Makkah Road.

The centre of Al Rwda sits about 622 m above sea level (SRTM open elevation data). Al Rwda is mainly apartment buildings.

Picture a restaurant owner in Al Rwda who notices that the kitchen floor feels damp near the back wall, or that the water bill has crept up with no change in trade. Often there is no visible puddle at all. Water can travel along pipes behind tiles, under counters or through a wall cavity, and by the time staining appears the problem has usually been running for some time. For a food business, every hour of unexplained water loss also means cleaning disruption, slippery floors and the risk of damage to equipment and stock.

Al Rwda is a residential district, mainly made up of apartment buildings, and it sits in the north-east part of Riyadh, roughly 9.6 km from the city centre. Restaurants here often share older plumbing and utility routes with the apartments above or beside them, so an owner cannot always assume that a leak is confined to their own unit. The centre of the area sits about 622 m above sea level, which is a useful reminder that water pressure and drainage behaviour in a building depend on local conditions, not only on the fittings themselves. Because the district is built up with apartment blocks, access to shared risers and ducts may need coordination with building management, which is worth arranging before any work starts.

The practical sequence is straightforward. First, read the water meter at closing time and again before opening, when no water is being used; a rise in that gap points to a leak. Second, check the areas that are hard to see: under sinks, around the grease trap, behind the dish station, and along floor-level pipework. Third, look at the tank and any storage vessels, noting whether their internal coating is intact, since coating repair is priced by area in the range of SAR 25–70 per m², so a clear picture of the surface helps with budgeting. Fourth, arrange detection that does not rely on breaking tiles first, and only open walls or floors once the likely location is confirmed. Finally, record the findings and repairs so the next water-bill review has a reference point.

For restaurants, visits are planned outside service hours and recorded for the premises file.

When do you need hidden water leak detection?

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

• A damp patch that slowly grows on a wall or ceiling
• A hissing or trickling sound in the wall after the taps are off
• The meter keeps turning with every tap closed

Causes we see in the field

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