Underground tank leak checks in Al Fakhrya start with the site itself. The centre of the neighbourhood sits at 24.6424, 46.6826, roughly 8 km from the centre of Riyadh, and the area covers an approximate radius of 1.2 km. Because the ground here is part of a compact urban grid, a technician first looks at where the tank sits relative to nearby drainage and paved areas. The centre of Al Fakhrya sits about 595 m above sea level, which matters for how surface water and groundwater may move around a tank, so the first check is the lay of the land around the restaurant rather than the tank alone. The nearest wadi channel is about 2 km from the centre of Al Fakhrya, so a technician will also note whether any runoff path from that direction could reach the excavation or the tank pit during heavy rain.

Other parts of the inspection depend on what is found on the day. The technician decides how the tank is tested, whether the lines and dispensing points need pressure or vacuum checks, and whether the chamber around the tank shows signs of water ingress or product staining. Any repair scope, such as coating work, is priced only after the inspection. Where internal coating is needed, the cost is quoted per square metre at SAR 25–70 per m², and the final figure depends on the tank's surface area and its condition once opened. None of these decisions can be made from a desk, so they are left to the visit.

To help the technician arrive prepared, the restaurant manager should have the tank's installation date, capacity, and any previous test or repair records ready, along with the location of fill points, vent pipes, and monitoring wells. Note any recent changes in fuel delivery volumes, unexplained stock losses, or wet patches near the tank pit. Clear access to the tank area, and a note of when the kitchen and dining room are quietest, will let the work go ahead without disrupting service. The more detail that is gathered beforehand, the more focused the visit and the clearer the findings will be.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

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.
• Construction joints and corners — we check this before anything else.

How we choose the tool in Al Fakhrya

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.
