Underground tank leak detection in Khafji: the local context

Team note on Khafji: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Main roads in or near Khafji: King Abdullah Road.

The centre of Khafji sits about 9 m above sea level (SRTM open elevation data). Khafji is about 2 km from the sea coast (OpenStreetMap).

Is there a way to tell whether the underground fuel or water tank beneath your hotel or serviced apartment building is leaking before the problem reaches your bill or your neighbours? In Khafji, where the centre of town sits about 9 m above sea level and the coast is roughly 2 km away, property owners ask this question more often than you might expect, because the ground conditions and proximity to the shore make a careful look at buried tanks worthwhile. A leak that goes unnoticed can seep into the surrounding soil and, over time, travel in ways that are hard to reverse, so early detection is the practical goal rather than a dramatic repair after the fact.

The inspection begins with a review of the tank's age, its material, and any records of past repairs or refilling patterns, followed by a check of stock levels against the fuel or water actually used. Technicians then examine the access points and surrounding area for signs of staining, odour or moisture. Where the tank's internal condition is in doubt, the coating may be assessed and, if needed, restored; internal coating is priced at SAR 25–60 per m², and the final figure depends on the surface area that has to be treated. Each step produces a written note so you can see exactly what was found and what, if anything, needs attention.

Before the visit, gather whatever you already have: the original installation documents, purchase and delivery records for the past year or so, and any earlier inspection reports. Note any unusual changes you have seen, such as a drop in tank levels without explanation, a damp patch near the building, or a strong smell in the car park or basement. Clear a path to the tank access covers and let the building staff know when the team will arrive, so that work can be scheduled without disrupting guests or tenants. Having this information ready helps the inspection focus on the right areas and gives you a clearer picture of the situation from the start.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs that call for 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

Where the problem usually comes from

• A common cause: a float valve that does not close, so water is wasted.
• Construction joints and corners — we check this before anything else.
• 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.

Mistakes that cost more

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