Is there a way to tell if the underground tank at your rest house or farm in Ghrnata is leaking before the water bill or the dry patch in the garden gives it away? Ghrnata is mainly villas, and many of the rest houses and farms around it rely on buried tanks that nobody sees for years. The area sits about 11 km from the centre of Riyadh, with its centre at 24.7912, 46.7437 and an approximate radius of 2.8 km, and it lies about 617 m above sea level. Those are the details a technician will note on the job sheet, because they help place your property within the wider Riyadh area and its local conditions.

The inspection starts with a visual check of the tank access points, pipework and the ground above the tank, looking for wet soil, staining or unexpected growth. The technician then checks the water level and records how it changes over a set period, which shows whether water is being lost. Where a leak is suspected, the inside of the tank is examined, and if the internal lining has broken down, repair options are discussed. Internal coating is priced at SAR 25–70 per m², so the size of the tank surface determines the range you can expect. The inspection report sets out what was found and what, if anything, needs attention.

Before the visit, clear access to the tank cover and pump room, and make sure gates and any locked areas can be opened on the day. Note any recent changes in your water use, bills or wet patches around the property, as these help the technician focus on the right spot. If you know the tank's approximate size, the age of the installation and when it was last cleaned or coated, write it down. Keep the area around the access point free of heavy items, and let the household or farm staff know when the inspection is due so that normal use of the water supply can be paused. A little preparation makes the visit quicker and the findings easier to act on.

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

Signs that call for 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
• The tank needs refilling faster than usual

Where the problem usually comes from

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

Tools we use in Ghrnata

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.
