Why underground tank leak detection differs in Al Aqyq

The centre of Al Aqyq is at 24.7740, 46.6309, about 8.1 km from the centre of Riyadh, with an approximate radius of 2.8 km. The approximate area shown on the map is centred here. The centre of Al Aqyq sits about 647 m above sea level (SRTM open elevation data).

The nearest wadi channel is about 0.7 km from the centre of Al Aqyq (OpenStreetMap). Main roads in or near Al Aqyq: King Fahd Road, Northern Ring Road, Prince Mohammed bin Salman bin Abdulaziz Road.

Al Aqyq sits at 24.7740, 46.6309, roughly 8.1 km from the centre of Riyadh, and the built-up area spans an approximate radius of 2.8 km. That makes it a compact district where many properties are close together and where a tank problem can quickly affect neighbouring plots. Our technicians plan emergency visits with this layout in mind, routing vehicles efficiently across the district and arriving prepared for the site conditions on arrival.

The centre of Al Aqyq is about 647 m above sea level, which is recorded from SRTM open elevation data. Elevation affects how groundwater and any leaking fuel or water move beneath a plot, so we take readings that reflect the local ground behaviour rather than assuming a flat profile. The nearest wadi channel lies about 0.7 km from the centre, according to OpenStreetMap. Because a wadi can carry runoff and shift soil after rain, we check whether seepage may be tracking toward low ground, and we advise owners to report any fresh wet patches or unusual smells in the surrounding soil, since these can point to a leak migrating beyond the tank itself.

Owners in Al Aqyq often make a few avoidable mistakes. They wait for a fuel smell or a drop in pressure to become obvious before calling anyone, when early signs such as slow, unexplained stock loss are easier to act on. They also assume a tank that looks sound from above is intact below ground, overlooking the internal condition of the walls. Where repairs are needed, the internal coating is priced at SAR 25–70 per m², so the size of the tank surface matters when estimating costs, and we explain that figure before any work starts. Finally, some owners delay a leak test after a repair, which leaves the result unverified. We recommend confirming every repair with a fresh check before the tank returns to service.

If water is flowing, close the main valve first, then call or message with photos.

Signs that call for underground tank leak detection

If you notice one of these signs in Al Aqyq, it is a good moment to talk to the team:

• The tank needs refilling faster than usual
• Damp or salt marks on the tiles above the tank
• A noticeable drop in the water level overnight

Where the problem usually comes from

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

Tools and methods, and when we use them

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.

Mistakes that cost more

• Waterproofing the tank before confirming the loss is from the tank and not the line
• Ignoring the float valve
