Is there a way to tell whether an underground tank is leaking without digging up the whole yard? For property owners in Al Salhya, Riyadh, that is usually the first question, and the answer depends on where the tank sits and how old it is. Al Salhya is centred at 24.6341, 46.7342, about 10.7 km from the centre of Riyadh, with an approximate radius of 1.2 km. The district's centre sits about 585 m above sea level, which is a useful reference point when a technician records site conditions. Because the area is compact and well defined, a survey can be planned around a clear location rather than a broad search, and the inspection can focus on the tank and its surroundings where a leak is most likely to show.

The inspection normally begins with a review of the tank's age, its material, and any recent changes in fuel or water usage that might point to a loss. The technician then checks the accessible parts of the system, including fill points, vent lines, and the surrounding ground, before moving to the testing stage. If the tank's internal lining is damaged, repair work is priced by area, with the internal coating quoted at SAR 25–65 per m². The final report should set out what was tested, what was found, and which repairs, if any, are recommended, so that the owner can decide on the next step with clear information in hand.

Before the visit, gather any records you have, such as installation papers, past repair invoices, and fuel delivery or consumption logs for the tank. Note any unusual signs you have noticed, including wet patches, sudden drops in stock, or smells near the tank area. Clear a safe path to the access points and make sure the technician can reach the fill and vent locations without moving heavy items. Having this information ready helps the inspection start quickly and gives a clearer picture of the tank's condition from the first hour on site.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for underground tank leak detection

These are the signs most often linked to underground tank leak detection:

• 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

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