Picture a homeowner in a villa with a buried fuel or water tank who notices the monthly bill creeping up, or a damp patch near the garden wall that never quite dries. They suspect something is wrong underground but cannot see it, and they are unsure whether the problem lies in the tank, the pipework or the ground around it. Many owners in this situation delay action because the tank is out of sight and the symptoms are easy to dismiss as ordinary wear.

Al Sfarat sits at about 24.6806, 46.6240, roughly 6.4 km from the centre of Riyadh, within an approximate radius of 1.2 km. The area is about 656 m above sea level, according to SRTM open elevation data, and the nearest wadi channel lies about 1.2 km from the centre, as recorded by OpenStreetMap. For an owner, these facts matter because a site on higher ground can still collect runoff from nearby slopes after heavy rain, and a wadi channel close by means surface water can move toward buried structures during storms. Together they suggest that moisture around a tank may come from outside the property as well as from inside it, so a leak check here should consider both the tank and the surrounding soil.

A sensible sequence starts with a written record: note when readings changed, when damp patches appeared, and whether they follow rainfall. Next, arrange a visual and pressure-based inspection of the tank and its fittings before any excavation, so the cause is identified rather than guessed. If the tank shows corrosion or porous walls, ask for an internal coating quote, which in this area is priced at SAR 25–65 per m², so the scope depends on the measured surface area. Finally, review drainage around the tank and address any runoff path that channels water toward it, because repairing the tank alone will not stop moisture arriving from outside.

Signs worth paying attention to

The following signs are worth checking before they grow:

• A noticeable drop in the water level overnight
• The pump runs for longer periods
• The tank needs refilling faster than usual

Where the problem usually comes from

• A common cause: a float valve that does not close, so water is wasted.
• Construction joints and corners.
• Cracks in the concrete tank walls or floor.

Tools and methods, and when we use them

The steps in order

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.
