Is there a way to tell whether the underground fuel tank on your Al Mlk Fhd property is leaking before the problem reaches the soil or groundwater? Here in Al Mlk Fhd, a district centred at 24.7414, 46.6725, about 3.1 km from the centre of Riyadh, property owners often ask this once they notice fuel odour near a building, a drop in stock levels, or unexplained wet ground around a fill point. Al Mlk Fhd sits roughly 629 m above sea level, and its approximate radius of 2.1 km means many sites are spread across fairly open ground where a leak can travel further than expected. Tank internal coating is priced at SAR 25–65 per m², so the cost of any repair work depends largely on the surface area that needs treatment, which is why an accurate inspection comes first.

A leak detection visit for underground tanks in this district follows a clear sequence. The technician starts by reviewing the tank records, fill logs and stock readings to check for mismatches that point to a loss. Next comes a visual check of the fill pipes, vent lines, dispensers and access covers for staining, corrosion or damp patches. The inspector then looks at the internal condition of the tank, since coating failure is a common cause of leaks inside steel tanks, and measures the affected surface to estimate what treatment would involve. Where the findings are unclear, further testing around the tank helps confirm whether fuel has escaped into the surrounding ground. Each step is recorded so the owner can see what was tested and what was found.

Preparation makes the visit faster and the results easier to act on. Before the inspector arrives, gather the fuel delivery receipts, daily stock records and any previous maintenance or repair reports for the tank. Clear access to the fill point, vent pipes, dispensers and the tank cover, and make sure the area is safe and free of parked vehicles or stored materials. Note when you first noticed the odour, staining or stock shortfall, and whether it has changed since. If the tank has been emptied or cleaned recently, say so, because that affects what can be inspected. Having these details ready lets the technician focus on the tank itself rather than on reconstructing the history, and gives you a clearer basis for deciding on repairs.

When do you need underground tank leak detection?

The following signs are worth checking before they grow:

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
