Before we start: what we know about 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 service-area circle on the map below is drawn from this point. Main roads in or near Al Aqyq: King Fahd Road, Northern Ring Road, Prince Mohammed bin Salman bin Abdulaziz Road.

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).

Al Aqeeq is a district about 8.1 km from central Riyadh, sitting at an elevation of roughly 647 metres above sea level, and it lies only 0.7 km from the nearest wadi channel. Its main routes include King Fahd Road, the Northern Ring Road, and Prince Mohammed bin Salman bin Abdulaziz Road, which together shape how crews reach residential buildings here. These traits matter for underground tank leak detection because a site close to a wadi can see groundwater movement and seasonal runoff that affect tank walls and surrounding soil. For this service, the first check is the tank's external condition and the water table around it, since that determines whether a leak signal is a true tank failure or an outside influence. The team then compares readings against the building's own water-usage pattern before opening the tank.

Before the visit, the building manager should gather the tank's installation records, any earlier repair notes, and a recent record of water consumption and pump operation. Clear access to the tank cover and the pump room saves time and keeps the inspection focused. Ask the team which tests they will run first, how they separate a wadi-driven effect from a real leak, and what they recommend if the tank lining has to be inspected from inside. If the team mentions interior lining work, ask them to explain the cost basis per square metre, so the quote can be checked against the area they measure.

For a whole building, a survey of the shared systems comes before unit-by-unit work.

When do you need underground tank leak detection?

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

The most common causes

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

Tools and methods, and when we use them

How the work is done, step by step

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.

Common mistakes we see

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