Picture a homeowner in Al Fwta who wakes up to a strong smell of fuel near the garden, or notices that the diesel level in an underground tank is dropping faster than usage explains. The worry is immediate: fuel can seep into soil, spread under paving and reach neighbouring plots. The owner needs someone who can respond quickly, confirm whether the tank is really leaking, and say clearly what needs fixing before anything else is done. Emergency calls like this are common in a district of this kind, where many properties rely on buried tanks for water or fuel.

Al Fwta sits at roughly 24.6417 north and 46.7105 east, about 8.8 km from the centre of Riyadh, and its built-up area covers an approximate radius of 1.2 km. The centre stands at about 588 m above sea level. For a leak investigation, this matters because the site is close enough to the city for rapid callouts, yet the local area is compact, so staff can reach most properties within the same zone without long delays. The elevation is a useful reference when checking how fluids may move across the land. Owners should also know that tank internal coating is priced per square metre, typically SAR 25–70 per m², so the scope of repair depends on the measured surface area of the affected tank rather than a fixed fee.

If you suspect a leak in Al Fwta, act in this order. First, stop adding fuel or water to the tank and switch off any pump that draws from it. Second, keep people and open flames away from the smell and avoid starting vehicles nearby. Third, record the time you first noticed the problem and the level readings you have, since these help the technician narrow the search. Fourth, call a leak detection service and describe the symptoms plainly. Fifth, allow the technician to test the tank and surrounding ground before any digging begins, so the repair targets the actual defect. Sixth, once the source is confirmed, agree on the coating or repair work in writing, with the area measured and the rate stated, before work starts.

If water is flowing, close the main valve first, then call or message with photos.

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
• The tank needs refilling faster than usual

The most common causes

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

How we choose the tool in Al Fwta

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.
