Why underground tank leak detection differs in Duba

Team note on Duba: 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.. Duba is about 0.2 km from the sea coast (OpenStreetMap).

The centre of Duba sits about 10 m above sea level (SRTM open elevation data).

Restaurants in Duba that rely on underground fuel or wastewater tanks most often face slow leaks that go unnoticed until stock figures stop adding up or the ground near the tank starts to smell. In a kitchen-heavy business, the usual warning signs are gradual drops in diesel or generator fuel that cannot be explained by use, damp patches in the forecourt or service yard, and a faint hydrocarbon or sewage odour that comes and goes with the weather. Because these signs develop slowly, a leak can run for a long time before anyone is sure what is happening, which is why a structured test is more useful than simply watching the dipstick.

The location of Duba shapes how that testing should be approached. The centre of the town sits about 10 m above sea level, and the coast is only about 0.2 km away. That combination matters for underground tanks: a site this close to the sea can have shallow groundwater and salt-laden soil, so water ingress into the tank or the surrounding backfill can be mistaken for product loss, and corrosion on steel tanks can progress faster than inland sites might expect. A good inspection therefore looks at the groundwater level around the excavation, checks whether water is entering through fittings or the fill pipe, and considers the condition of the tank's internal lining. Where a tank does need recoating, the cost of internal coating is typically quoted at SAR 25–60 per m², so the size of the tank is an important part of planning any repair budget.

Before the visit, ask the provider how they will separate true product loss from water entering the tank, and whether their method works on a tank that is still in use. Ask what equipment they bring, how long the test itself takes, and what the report will include, such as tank dimensions, measured readings and photos of the fittings. Confirm whether they will check the tank, the pipework and the dispensers, since leaks often sit in more than one place. Ask for a written quote that separates the testing fee from any coating or repair work, and find out how the findings will be explained to you before any work starts. Clear answers to these questions will tell you whether the visit will give your restaurant a reliable picture of what is happening underground.

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

Signs worth paying attention to

If you notice one of these signs in Duba, it is a good moment to talk to the team:

• 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 — we check this before anything else.
• A common cause: cracks in the concrete tank walls or floor.
• A common cause: construction joints and corners.

How we choose the tool in Duba

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.

Common mistakes we see

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