A rest house owner in a quiet corner of the city often notices the problem only when the water bill climbs, the garden turns soft and damp in one patch, or a pump starts running longer than it should. Underground tanks at farms and weekend properties are easy to forget because they sit out of sight, and a slow leak can run for a long time before anyone connects it to the ground around it. For an owner who visits only on some weekends, that delay can mean more lost water and more repair work when the problem finally surfaces.

Al Rhmanya is centred at 24.7170, 46.6590, about 1.7 km from the centre of Riyadh, with an approximate radius of 1.2 km. Its centre sits about 619 m above sea level. For a property owner, these facts mean the site is close enough to the city centre for regular inspection visits, yet the neighbourhood is compact, so the land and its drainage behave as one area. A tank in this part of Riyadh should be checked with the local ground conditions and the elevation in mind, because water moves through the soil with the slope of the land, and surface signs may appear some distance from the actual leak. Tank internal coating is priced at SAR 25–70 per m², so the size of the tank will shape the overall cost of any protective work.

The practical steps begin with a simple record. Note the tank's capacity, its age, and the last time it was inspected or coated. Next, track water use for several weeks and compare it with normal consumption, since an unexplained rise is often the first clue. Then walk the grounds after rain or irrigation and look for soft soil, unusual greenness, or standing damp. If any of these signs appear, arrange an inspection of the tank and its pipework before digging starts. Where coating is needed, request a quote per square metre so the figures can be compared fairly. Finally, keep the inspection and repair records together so the next owner or visitor can see the history of the tank.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

When do you need underground tank leak detection?

The following signs are worth checking before they grow:

• 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 most common causes

• A float valve that does not close, so water is wasted.
• A common cause: cracks in the concrete tank walls or floor.
• Construction joints and corners.

Tools we use in Al Rhmanya

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.
