What is specific about Al Rbya for underground tank leak detection

The centre of Al Rbya is at 24.7980, 46.6648, about 9.4 km from the centre of Riyadh, 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 Rbya sits about 661 m above sea level (SRTM open elevation data).

Al Rbya sits with its centre at 24.7980, 46.6648, roughly 9.4 km from the centre of Riyadh, and the built-up area spreads across an approximate radius of 1.2 km. For a service business, that compact footprint and modest distance from the capital mean crews can reach most rest houses and farms in the area within a short trip, which keeps response times practical when a tank is suspected of leaking. Owners on the outskirts should still confirm access routes before booking, since properties can be spread out over open ground.

The centre of Al Rbya is about 661 m above sea level, according to SRTM open elevation data. Altitude affects the work mainly through ground conditions and drainage: water and soil behave differently on a slightly elevated site, so the technician checks how surface runoff moves around the tank before testing. That check helps separate a true underground leak from rain or irrigation water that has simply collected near the tank, which is why the inspection starts with the site rather than the tank alone.

Tank internal coating is priced at SAR 25–70 per m², and this range is shown so owners can understand what repair work may involve before any decision is made. The final cost depends on the surface area that needs treatment, the condition of the existing lining, and how much preparation is needed. Owners should ask for a written breakdown per square metre so they can compare the scope of work and avoid surprises. Common mistakes owners avoid include delaying the test after noticing a drop in water level, assuming a leak is always obvious, skipping the check of nearby pipes and pumps, and accepting a repair quote without measuring the tank surface first.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

The following signs are worth checking before they grow:

• Damp or salt marks on the tiles above the tank
• The tank needs refilling faster than usual
• The pump runs for longer periods
• A noticeable drop in the water level overnight

Where the problem usually comes from

• Cracks in the concrete tank walls or floor.
• Construction joints and corners.
• A float valve that does not close, so water is wasted — we check this before anything else.

Tools we use in Al Rbya

How the work is done, step by step

1. Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
2. Documented level test: Filling and use are stopped and the level is recorded against time.
3. Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
4. Checking the body and connections: Inlet, outlet and overflow connections are inspected.
5. Recommendation: You get the next step in writing: repair, waterproofing or a line test.
