Underground tank leak detection for residential buildings in Al Slama starts with the location itself, because the area is well defined and easy to reference on a site plan. The centre of Al Slama sits at 24.6814, 46.7042, about 4.6 km from the centre of Riyadh, with an approximate radius of 1.2 km. Knowing this helps the technician confirm the building falls within the service area and record accurate coordinates before any work begins. The centre of Al Slama also sits about 605 m above sea level, a fact the technician can note when logging the site, since elevation is recorded alongside the location for reference.

Several checks are left to the site visit, because they depend on what is physically present at the building. The technician will inspect the tank's condition, look for signs of water ingress or staining around the tank and its fittings, and check how the tank's inner surface is holding up. Where coating is involved, the cost for tank internal coating is quoted at SAR 25–70 per m², but the final figure depends on the surface area measured on the day, so the area must be confirmed in person. Access routes, the depth of the tank, and any nearby pipework are also assessed on site, since none of these can be judged from a distance.

To help the technician, residents and building managers should prepare a few details before the visit. Note the building's exact address and the approximate capacity of the underground tank if it is known, and mention any recent changes in water levels, damp patches, or unusual pump activity. Clear access to the tank cover and the plant area saves time. Having previous maintenance records or photographs of the tank ready also lets the technician compare past conditions with the current ones and focus the inspection where it matters most.

For a residential building, shared risers, tanks and pumps are checked as one system.

When do you need underground tank leak detection?

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

• 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

Where the problem usually comes from

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

How we choose the tool in Al Slama

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.
