Wondering whether the underground water tank beneath your building is quietly losing water? In Al Alya, a district that is largely commercial, with shops and offices, many buildings share the same ground-level storage needs, and a slow leak can go unnoticed for a long time. The centre of Al Alya sits at 24.6931, 46.6845, about 2.5 km from the centre of Riyadh, with an approximate radius of 3 km, and it lies about 622 m above sea level. Those facts matter for planning a visit, because the district's position relative to the city and its elevation are reference points that help technicians record the site accurately.
The inspection normally starts with a review of the tank's history, including its age, its material and any past repairs, followed by a visual check of the surrounding ground and the inlet and outlet connections for signs of dampness or staining. The technician then tests the tank's water level over a set period to see whether the volume is falling when no water is being drawn. Where the tank has a coated interior, the condition of the lining is examined, since a failing coating is a common route for leaks. Coating work for tank interiors is priced at SAR 25–70 per m², which is useful to know if the inspection shows the lining needs attention. Each step is recorded so the owner receives a clear account of what was found.
Before the visit, gather whatever records you have about the tank, such as installation papers, earlier maintenance reports and any invoices for repairs. Note any unusual signs you have noticed, including a sudden rise in the water bill, damp patches in the basement or parking area, or a musty smell near the storage space. Make sure the technician can access the tank cover and the pump room, and let the building's tenants know in advance so that water use can be kept steady during testing. Having these details ready helps the inspection run smoothly and gives you a clearer picture of whether repair or coating work is needed.
For a whole building, a survey of the shared systems comes before unit-by-unit work.
When do you need 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.
- Construction joints and corners — we check this before anything else.
- A common cause: a float valve that does not close, so water is wasted.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
How the work is done, step by step
- Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
- Documented level test: Filling and use are stopped and the level is recorded against time.
- Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
- Checking the body and connections: Inlet, outlet and overflow connections are inspected.
- Recommendation: You get the next step in writing: repair, waterproofing or a line test.
