Is there a way to check whether an underground fuel or water tank under a restaurant in Al Mayzyla is leaking before the problem reaches the kitchen or the ground? For property owners here, that question usually comes up after a smell, a drop in stock, or a damp patch near the service yard. Al Mayzyla sits at 24.7851, 46.8450, about 18.9 km from the centre of Riyadh, within an approximate radius of 1.2 km, and its centre lies about 579 m above sea level. The nearest wadi channel is about 0.4 km from the centre, which matters because surface water after rain can carry contamination toward low ground, so a leak here is worth checking early rather than waiting for visible signs.

The inspection follows a set sequence. The technician first reviews the tank's age, its material and the pipe runs that connect it to the dispensers or the wash area. Next comes a test of the tank and lines for loss, followed by a check of the surrounding soil and any monitoring points for signs of fuel or water movement. Where the internal lining is worn, the technician notes the affected surface area so the owner can compare repair options; internal coating is typically quoted at SAR 25–70 per m², and the final figure depends on the area measured on site. The report then sets out what was found, what is urgent and what can wait.

Before the visit, gather the tank's installation papers, any previous test records, and the stock logs for the past several months, since a gradual drop in stock is often the first clue. Clear access to the tank cover, the fill points and the pump area so the technician can work without moving equipment. Note any recent smells, wet patches, or changes in water pressure, and mention whether the site has had heavy rain or flooding near the wadi. Having these details ready lets the inspection start immediately and helps the report reflect the actual conditions at your restaurant.

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:

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

The most common causes

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

Tools and methods, and when we use them

From the first visit to the report

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.
