Al Adama is about 2.7 km from the sea coast (OpenStreetMap). Many buildings in Al Adama have been in use for decades. In older buildings, corroded joints and old lines are a frequent source of hidden leaks.

The centre of Al Adama sits about 12 m above sea level (SRTM open elevation data).

Picture a villa owner in Al Adama who has noticed that the water bill has crept up for no clear reason, or that the damp patch near the garden wall keeps returning. The underground tank may be out of sight, but it is often the first place to look when water is unaccounted for. Owners of older homes in this kind of setting usually rely on a tank that has been in service for a long time, and they tend to discover a problem only after it has already caused damage.

The local facts shape what that owner should expect. Al Adama is a residential area at about 12 m above sea level, roughly 2.7 km from the coast, and located close to the centre of Dammam, around 1.9 km away, with an approximate radius of 1 km. Many buildings here have been in use for decades, so the tanks serving them may be ageing, with coatings that have worn down over the years. The centre of the area sits at 26.4328, 50.1017, which is useful if you need to describe your location to a technician. Because the neighbourhood has many long-standing buildings, a tank that was installed decades ago may have never been inspected in a structured way, which is why a leak can run for a long time before anyone notices.

Practical steps help keep the process orderly. First, record your water meter reading at the same time each day for about a week while no taps are in use, so any drop or gain is visible. Second, check the surface around the tank and the adjoining walls for soft ground, wet patches, or unexplained greenery. Third, arrange for a technician to test the tank and its connecting pipes, and ask for a written account of what was found. Fourth, if the tank needs repair, request a quotation that lists the internal coating work per square metre, which typically falls in the range of SAR 25–60 per m², so you can compare offers on a like-for-like basis. Finally, keep the report and the quotation together with your property papers, so future maintenance is easier to plan.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

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
• Damp or salt marks on the tiles above the tank

Where the problem usually comes from

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

Tools we use in Al Adama

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.
