Wondering whether your underground fuel or water tank in Al Farwq, Riyadh, is leaking without you knowing? That is a fair question for any property owner here, and the first step is understanding where the neighbourhood sits. The centre of Al Farwq is at 24.6494, 46.7786, about 12.6 km from the centre of Riyadh, with an approximate radius of 1.2 km. The centre of Al Farwq sits about 624 m above sea level, so the area is well inland on the Riyadh plateau. Tanks in this part of the city are often buried in sandy, dry ground, which can hide slow seepage until it becomes a larger problem.

A leak detection visit usually follows a clear sequence. The technician first reviews the tank's age, material, and history of fuel or water levels, then checks the visible fittings, pipework, and access points for signs of wetness or staining. Where the tank is accessible, the inside surface is examined, and the condition of the internal coating is assessed, since coating repairs are priced per square metre, typically SAR 25–65 per m², depending on the work needed. Findings are recorded so you can compare results over time and decide on any repairs with a clear picture of the condition.

Before the visit, gather what will make the inspection faster and more useful. Find any previous service records, installation paperwork, and details of the tank's capacity and contents. Note any recent changes in fuel or water consumption, unexplained drops in level, or odours near the tank area, as these details help the technician focus on likely problem spots. Clear access to the tank cover, fill points, and nearby pipework saves time on the day. Keeping these items ready means the visit can concentrate on what matters: confirming whether a leak exists and what it would take to fix it.

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

When do you need underground tank leak detection?

If you notice one of these signs in Al Farwq, it is a good moment to talk to the team:

• 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

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

Tools we use in Al Farwq

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.
