Is there a leak in the underground tank at my Al Jzaa property, and how much will it cost to find out? Al Jzaa sits at about 24.5667, 46.7500, roughly 18 km from the centre of Riyadh, and its built-up area extends across an approximate radius of 1.2 km. The town stands about 571 m above sea level, and the nearest wadi channel runs about 1 km from its centre. Those are the local conditions your tank has to contend with, so a leak check here should account for the ground around it as well as the tank itself.

Inspection for underground tank leaks usually follows a set sequence. The technician first reviews the tank's age, its material, and any history of repairs or unexplained drops in water or fuel levels. Next comes a visual and access check of the fill points, vent lines and inspection covers, followed by testing of the tank and its connecting pipework. If a leak is confirmed or suspected, the report will set out where the damage appears to be and whether the tank can be repaired or needs replacing. Where repair is the route, the interior of the tank can be treated with an internal coating, which is priced at SAR 25–65 per m². The final figure depends on the tank's surface area and the condition of its walls, so ask for a written quote that lists the square metres measured.

Before the visit, gather anything that shows how the tank has behaved over time, such as past maintenance records, installation papers, and notes on any water or fuel loss you have noticed. Clear access to the tank cover, the pump area and the pipe runs will save time on the day, and it helps to mark any spots where you have seen wet ground or unusual smells. Confirm who will be on site and how long they expect to be there, and ask for the test results in writing. Keeping these details ready means the inspection can focus on the tank itself and you leave with a clear answer about the leak and the next steps.

Signs that call for underground tank leak detection

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

Causes we see in the field

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

How we choose the tool in Al Jzaa

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.
