What is specific about Al Khlyj for underground tank leak detection

The centre of Al Khlyj is at 24.7768, 46.8035, about 14.7 km from the centre of Riyadh, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. Main roads in or near Al Khlyj: King Abdullah Road, Al Sahaba Road, Prince Bandar bin Abdulaziz.

The centre of Al Khlyj sits about 593 m above sea level (SRTM open elevation data).

Al Khlyj sits at 24.7768, 46.8035, roughly 14.7 km from the centre of Riyadh, within an approximate radius of 1.2 km. That position puts many rest houses and farms within easy reach of our teams, so visits can be scheduled around the normal rhythm of the area rather than planned from the city. The centre of Al Khlyj sits about 593 m above sea level, which matters for underground tanks because elevation affects how water tables and ground moisture behave around buried steel and concrete. Our technicians account for this when they read pressure and water-level results, so a change that looks like a leak is not mistaken for a normal seasonal shift.

Distance and terrain shape the practical side of the work. Because the site is a short drive from Riyadh but still spread across open ground, we bring tools for testing that do not depend on mains power, and we plan for access routes that may be unpaved after rain. The 593 m elevation also means ground conditions can change between a low corner of a farm and a higher section near a rest house, so tests are set out tank by tank rather than assumed to be the same across the property. The interior coating of a tank is a major part of what we check, and coating work is priced at SAR 25–70 per m². That range depends on the surface condition, the coating system and the access inside the tank, so a clear inspection first helps owners understand where their money is going before any repair or recoating is agreed.

Owners in Al Khlyj often make the same few mistakes, and our service is built to avoid them. Many wait until a water bill rises or a pump runs longer than usual before calling anyone, when a small leak has already spread into the surrounding soil. Others assume a tank is sound because the surface above looks dry, even though underground leaks can travel sideways. Some owners also compare coating quotes only by price per square metre without asking about preparation, which is where long-lasting results are decided. We recommend a baseline test when a property is first set up, a recorded check after any ground work nearby, and a written inspection before choosing a contractor, so each decision rests on evidence from the tank itself.

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

When do you need underground tank leak detection?

The following signs are worth checking before they grow:

• The pump runs for longer periods
• A noticeable drop in the water level overnight
• Damp or salt marks on the tiles above the tank

Where the problem usually comes from

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

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

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