Al Shrwq sits at roughly 21.5673 north, 39.2990 east, about 13.3 km from the centre of Jeddah, with an approximate radius of 1.2 km. At around 75 metres above sea level, and some 14.3 km from the coast, the neighbourhood is set back from the sea but still within reach of the city's groundwater and soil conditions. The nearest wadi channel runs about 1.2 km from the centre of Al Shrwq, so storm-water flow and soil moisture can differ noticeably from one villa plot to the next. For that reason, our first check on any underground tank here is the ground around it: the surrounding soil, the drainage direction of the plot, and whether water tends to collect near the tank after rain. A technician will want to know how close a tank sits to boundary walls and to any wadi-facing side of the property before deciding how the test is set up.

Some things can only be judged on the day. The exact condition of the tank shell, the state of its fittings and manhole covers, the depth of the burial, and the presence of any groundwater in the excavation pit are all visual or hands-on assessments. The technician will also decide on the testing method once the tank has been inspected, since the right approach depends on the tank's material, size and access. If a internal coating is in question, the technician will examine it in person and estimate the area involved, because coating work is charged at SAR 25–65 per m², and the true rate depends on the surface, the condition of the existing layer and the extent of the damage. No price should be assumed before that inspection.

To help the technician arrive prepared, note the age of the tank if you know it, any past repairs, and where the fill and vent pipes run. Mention any recent changes to the villa's water use, such as a new pump or extra storage, and whether the tank has been emptied before. Share the nearest access point for a vehicle, as well as gate hours if the property is guarded. Clear information about these points lets the visit focus on the ground around Al Shrwq rather than on questions that could have been answered in advance.

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

Signs that call for underground tank leak detection

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

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

Where the problem usually comes from

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

How we choose the tool in Al Shrwq

The steps in order

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.
