Underground tanks on rest houses and farms most often fail quietly: a slow seep through a corroded joint, a cracked fitting, or a line that has been losing water for months before anyone notices a drop in pressure or an unexplained rise in the water bill. In Al Mwtmrat, where many properties rely on stored water for irrigation, livestock and guest use, that slow loss can go unnoticed for a long time. Our leak detection visit starts by checking the tank shell, inlet and outlet fittings, and the connecting pipework for the signs that usually point to a leak, before any equipment is switched on.

The local setting shapes how we approach the job. The centre of Al Mwtmrat sits at 24.6706, 46.6869, about 4.9 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most properties here sit within a short drive of the city but are still rural enough to have their own private storage. The centre of Al Mwtmrat sits about 614 m above sea level (SRTM open elevation data), which means water pressure at lower outlets and on sloped access lines can differ from what a technician might expect on flatter sites. We take this into account when reading pressure readings and when deciding where to test first.

Before the visit, ask us a few practical questions so we can plan the right inspection. Tell us the approximate age and material of the tank, whether it has ever been recoated, and when you last noticed a drop in water levels or a change in pump behaviour. If the tank interior has been worn, our team can also discuss the internal coating option, which is priced at SAR 25–70 per m², depending on the surface area and the condition of the existing lining. Ask us how long the visit is likely to take on your property, what access we will need to the tank and pump room, and what written findings you will receive afterwards.

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

Signs worth paying attention to

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

Causes we see in the field

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

How we choose the tool in Al Mwtmrat

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.
