Underground tank leak checks for villas in Al Wrwd, Jeddah, start with the location itself. The centre of Al Wrwd sits at 21.5189, 39.2046, about 4.3 km from the centre of Jeddah, with an approximate radius of 1.2 km. The area lies about 18 m above sea level and roughly 3.4 km from the sea coast. These facts matter because the technician will first look at how the tank sits relative to the house, the drainage and the access route, rather than assuming a uniform setup across the district. Elevation and distance from the coast help explain why groundwater and soil conditions can differ from one plot to the next, so the first checks focus on the tank's surroundings and its connection to the villa's supply lines.

Other parts of the inspection are left to the site visit. The technician will judge the tank's condition in person, including the state of its walls, the joints, the fittings and any signs of seepage or staining around the access points. Whether an internal coating is needed, and how much of the surface it would cover, can only be confirmed once the tank has been seen. Coating is usually estimated per square metre, and the typical range is SAR 25–65 per m², but the final area depends on the tank's size and condition, which the technician will measure on site. Decisions about repair versus replacement also belong to the visit, after the leak source is found.

To help the technician, have the following information ready before the visit: the tank's approximate capacity, its age, the material it was built from, and any past repairs or leak history you know of. Note where the water level has dropped or where a damp patch has appeared, and whether the problem is worse after heavy use of the supply. Make sure the access cover and the area around the tank are clear, and let the technician know where the pump and pipework run. Clear information at the start lets the visit focus on finding the leak and planning the right fix.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

When do you need underground tank leak detection?

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
• Damp or salt marks on the tiles above the tank

Causes we see in the field

• 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.

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.
