Underground tank leak detection in Al Salhya, Riyadh, begins with the location itself. The centre of Al Salhya sits at 24.6341, 46.7342, about 10.7 km from the centre of Riyadh, and the neighbourhood spreads over an approximate radius of 1.2 km. Because the area is a defined, compact district on the city's edge, a technician can plan access, travel time and site logistics before arriving. The centre of Al Salhya also sits about 585 m above sea level, which is a useful reference when a technician notes ground conditions and drainage on the property, since elevation influences how water moves across and beneath a plot.

The site visit itself decides most of what follows. The technician checks the tank's condition, the pipework connected to it, the fill and vent points, and the surrounding ground for signs of moisture or staining. Whether a tank needs internal work, and how much, depends on what is found in person, so no assumption is made from the desk. If the inspection shows the inner surface has deteriorated, the work may include a fresh internal coating, which is priced in the range of SAR 25–65 per m². The exact figure for a given tank depends on its measured internal area and the condition of its surfaces, and that is confirmed on site rather than estimated in advance.

To help the technician arrive prepared, it is worth noting the tank's age, its capacity, what has been stored in it, and any previous repairs or reports. Describe any symptoms you have noticed, such as a drop in stored volume, a fuel or water smell near the fill point, or damp patches above the tank area, and when you first saw them. Clear access to the tank cover and to the surrounding ground, and information about where the pipework runs, will let the visit focus on the leak itself. Keeping these details together in one place makes the inspection faster and the findings easier to act on.

Signs worth paying attention to

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 — we check this before anything else.
• A common cause: construction joints and corners.
• A float valve that does not close, so water is wasted.

How we choose the tool in Al Salhya

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.
