Underground tank leak detection in Al Shmysy: the local context

The centre of Al Shmysy is at 24.6238, 46.7000, about 10.3 km from the centre of Riyadh, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. Main roads in or near Al Shmysy: King Fahd Road, Asir, Madinah Road.

The centre of Al Shmysy sits about 587 m above sea level (SRTM open elevation data). The nearest wadi channel is about 1.4 km from the centre of Al Shmysy (OpenStreetMap).

Underground tanks on rest houses and farms most often fail quietly. A slow seep through a corroded joint, a cracked fitting or an aging coating can go unnoticed for months, while water use creeps up and the ground around the tank stays damp. By the time a stain or smell appears, the leak has usually been running for some time. Our leak detection visit is built around finding that slow loss early, before it spreads into the surrounding soil or forces a costly excavation.

Al Shmysy changes how we approach each job. The centre of the area sits at 24.6238, 46.7000, about 10.3 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most properties here are spread out and often rely on a single storage tank rather than a connected network. It also sits at about 587 m above sea level, and the nearest wadi channel lies about 1.4 km from the centre, which means seasonal runoff can saturate the ground around buried tanks after rain. We therefore check the tank's surroundings and drainage routes as well as the tank itself, and we time the test to reflect how the soil actually behaves on that site. Where a tank has an internal coating, we also look at its condition closely, since coating work is priced at SAR 25–70 per m², and that cost depends heavily on the surface area that needs attention.

Before the visit, it helps to have a few details ready. Tell us the approximate tank size, how old it is, whether it has been repaired or re-coated before, and whether you have noticed any changes in your water meter reading or damp patches near the tank or pipework. Let us know how the property is supplied and whether any irrigation lines run close to the tank. If the rest house or farm sits near a wadi or low ground, mention that too. With this information, the technician can plan the right test, bring the correct equipment and give you a clear picture of what is happening underground before any work begins.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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

The most common causes

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

How we choose the tool in Al Shmysy

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.
