Underground tank leak detection in Al Skyrynh, Riyadh, starts with the location itself. The centre of Al Skyrynh sits at 24.6164, 46.7178, about 11.6 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most duplex properties here are reached quickly and the first check is simply whether the tank is in the same area as the rest of the building's water and drainage lines. The ground in the district is also raised: the centre of Al Skyrynh sits about 585 m above sea level, which matters because gravity-fed lines and tank outlets can behave differently from those in lower parts of the city. Technicians will look at the tank's position relative to the house first, then check the inlet, outlet and any visible pipework before any testing begins. The nearest wadi channel is about 2.3 km from the centre of Al Skyrynh, so surface water rarely reaches this site directly, but the first questions remain about whether there is standing water, damp soil or staining around the tank cover.

What is left to the site visit is the part that cannot be judged from a description. The technician needs to open the access point, look at the condition of the tank walls and seams, and decide which test suits the tank's size and age. Where coating is a question, the internal coating price range is SAR 25–70 per m², and the actual figure depends on surface area and the work needed, so that is confirmed only after measurement on site. Pressure or level tests, and the choice between them, are also decided once the technician has seen the tank and its fittings. Nothing about the result should be assumed before the inspection is complete.

To help the technician, have the following ready: the tank's approximate capacity and when it was installed, any past repair records, and a note of any recent drop in water level or unexplained damp patches near the tank. Make sure the access cover and the area around it are clear, and tell the technician whether the duplex shares its tank with a neighbouring unit. If a previous contractor worked on the tank, provide their notes. Good preparation shortens the visit and lets the technician focus on finding the leak rather than locating the tank.

In a duplex, the two floors often share lines, so tests are done floor by floor.

Signs that call for underground tank leak detection

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.
• A common cause: cracks in the concrete tank walls or floor.

How we choose the tool in Al Skyrynh

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.

Common mistakes we see

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