Do I need to worry about a leaking underground tank under my duplex in Mrkz Al Mlk Abdallh Al Maly? It is a fair question, and the answer depends on the ground around the tank. The area sits at about 24.7656, 46.6405, roughly 6.8 km from the centre of Riyadh, within an approximate radius of 1.2 km. The centre of Mrkz Al Mlk Abdallh Al Maly sits about 634 m above sea level, and the nearest wadi channel is about 0.9 km away. Because the district is close to a natural drainage line, water and any leaked fuel can move through the ground in ways that are easy to miss from the surface, so a tank that has been quiet for years may still deserve a check.

Our inspection for duplexes in this district starts with a review of the tank's age, its material and the history of fuel deliveries and stock readings. The technician then carries out a tightness test on the tank and its piping, followed by a check of the fill, vent and dispensing lines for signs of seepage. Where the records or the test results raise doubt, the team looks at the surrounding soil and at nearby groundwater monitoring points. If a repair is needed, the tank's internal coating can be restored at a cost of SAR 25–70 per m², with the final figure set by the surface area of the tank after the survey. Each step is written up so the owner can see exactly what was tested and what was found.

Before the visit, gather the tank's installation papers, any previous inspection or repair reports, and your monthly fuel purchase and stock records for the last year. Note where the tank and its pipes are located on your plot, and tell us about any past spills, odours in the garden, or wet patches that appear after rain. Make sure the technician can access the fill cap, the vent pipe and the inspection chamber, and clear any vehicles or stored items from those spots. With this information ready, the visit can focus on the tank itself and give you a clear answer on whether it is safe to keep in service.

In a duplex, the two floors often share lines, so tests are done floor by floor.

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

The most common causes

• A common cause: 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.

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.
