Underground tank leaks in Al Azyzya usually begin quietly. A slow loss of fuel or water, a reading on the gauge that drifts from one week to the next, or a damp patch near the pump island can be the first sign that a buried tank or its pipework is failing. In an emergency, the priority is to stop further loss, protect people and nearby property, and then pinpoint where the leak is coming from before any repair work starts. Because the problem is often hidden underground, the first step is to confirm the leak and its likely location rather than digging blindly.

Al Azyzya sits at 24.5877, 46.7701, about 17 km from the centre of Riyadh, within an approximate radius of 3 km. That distance matters because a call-out here is a local job, not a trip across the city, so the team can usually reach the site quickly once an emergency is reported. The area also sits about 589 m above sea level, which is a useful detail for the crew to know when they plan equipment and assess ground conditions. Local access, the age of the tank and the type of surrounding ground all shape how a leak test is set up, so the approach is adjusted to the property rather than applied as a standard routine.

Before the visit, it helps to have a few details ready. Note when you first noticed the loss, whether it is fuel or water, and whether the level drops steadily or only at certain times. Let the team know the age of the tank, any previous repairs, and whether the inside surface has been treated. Where a tank is found to need internal work, internal coating is typically priced at SAR 25–70 per m², so knowing the tank's size helps set expectations early. Finally, make sure the site is clear and that someone can meet the crew at the gate, so the first assessment can start without delay.

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:

• A noticeable drop in the water level overnight
• The pump runs for longer periods
• The tank needs refilling faster than usual

Causes we see in the field

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

How we choose the tool in Al Azyzya

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.

Mistakes that cost more

• Waterproofing the tank before confirming the loss is from the tank and not the line
• Ignoring the float valve
