Is there a way to know whether the underground fuel or water tank on my property is leaking before the damage spreads? For many owners in Al Mlk Abdallh, the first sign is a drop in stored volume that cannot be explained by use. Al Mlk Abdallh is a neighbourhood centred at 24.7324, 46.7414, about 7 km from the centre of Riyadh, with an approximate radius of 1.2 km. The centre sits about 638 m above sea level, according to SRTM open elevation data. Because tanks here are buried in local soil, a leak can travel unseen, which is why a structured inspection is worth arranging rather than waiting for a visible stain or a smell.

The inspection follows a clear sequence. The technician first reviews the tank's age, material and the records of recent refills and consumption, so that the readings have a baseline to compare against. Next comes the physical check of accessible parts, including fittings, pipework, manhole covers and the area around the fill and vent lines. Where the findings point to corrosion on the inside of the vessel, the report will note the condition of the internal surface, and if repair is needed, the cost is usually estimated per square metre of tank internal coating, which is quoted at SAR 25–65 per m². The final report sets out what was found, what is urgent, and what can wait, written so the owner can make a decision without guesswork.

Before the visit, gather the purchase or installation papers for the tank, any previous inspection or repair reports, and the monthly fuel or water records for at least the last few months. Note any unusual odours, damp patches, or changes in pump behaviour, and make sure the technician can reach the tank area, the pump room and the access points without obstruction. Clear the ground above the tank of vehicles and stored items. Having these details ready means the inspection can focus on the tank itself, and the owner leaves with a clear answer rather than a list of open questions.

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

Signs worth paying attention to

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

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

Causes we see in the field

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

Tools we use in Al Mlk Abdallh

From the first visit to the report

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.
