Consider a homeowner in Al Farwq, Riyadh, who has noticed that the water bill has crept up without any obvious reason, or that the ground near the garden tap stays damp even after the irrigation has stopped. Underground water tanks are out of sight, so a slow leak can run for a long time before anyone sees a sign of it. Owners of villas, small compounds and shops often find out only when a pump runs longer than usual or a wall shows dampness.

The local facts matter here. Al Farwq sits at roughly 24.6494 north and 46.7786 east, about 12.6 km from the centre of Riyadh, within an approximate radius of 1.2 km. The area's centre is around 624 m above sea level. For a homeowner, this means the tank is not far from the city centre but still sits in a district where distance from the main network and the height of the ground shape how the tank is filled and pumped. Both factors make it worth checking the tank and its pipework regularly rather than assuming the tank is sound because nothing has gone wrong yet.

If you suspect a leak in Al Farwq, take these steps in order. First, record your water meter reading at a time when no taps or irrigation are running, then take a second reading a day later to confirm the loss. Second, check the tank walls, the inlet and outlet pipes and the area around the tank for damp patches, cracks or soft ground. Third, if the loss is confirmed, arrange a detection survey before any digging starts, so the exact point of the leak is found rather than guessed. Fourth, if the inside of the tank is worn, ask for the internal coating to be assessed; coating work is usually priced at SAR 25–65 per m², depending on the surface area and condition. Finally, keep written records of readings, findings and repairs so that future checks can be compared easily.

Signs that call for underground tank leak detection

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
• A noticeable drop in the water level overnight

Causes we see in the field

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

Tools and methods, and when we use them

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.
