Underground tank leak detection in Aldarb: preventive periodic check

Before we start: what we know about Aldarb

The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Aldarb is about 18.7 km from the sea coast (OpenStreetMap).

Do I really need my underground fuel or water tank checked if nothing seems wrong? For many property owners in Aldarb, that is the natural first question, and the short answer is that a leak can stay hidden for a long time. Aldarb sits about 79 m above sea level, and its centre is roughly 18.7 km from the coast. Those facts matter little to a tank buried in the ground, but they tell you this is an inland town where tanks are typically left undisturbed for years, so routine checks are a sensible habit rather than a reaction to a known problem.

Preventive inspection follows a clear sequence. The technician begins by reviewing the tank's age, its contents, and any past repairs, then checks the access points and fill lines for signs of wear. Next comes the testing of the tank itself, looking for changes in levels or pressure that suggest a breach. Where the internal surface is exposed, the technician assesses the tank internal coating, which is priced at SAR 25–60 per m², so the quote you receive will depend on the surface area that needs work. The visit ends with a written summary of what was found and which items, if any, should be scheduled for repair.

Preparation makes the visit faster and more useful. Clear the area around the access cover so the technician can reach it safely, and gather any previous inspection reports, installation papers, and records of fuel or water deliveries. Note any unusual readings, smells, or wet patches you have seen nearby. If the tank supplies a building that is occupied, let the household or tenants know when the visit is planned. Having these details ready lets the technician focus on the tank rather than on questions, and gives you a clear baseline for future periodic checks.

Preventive checks follow a written schedule instead of waiting for a fault.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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 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.

How we choose the tool in Aldarb

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.
