Have you ever wondered whether the water tank under your villa in Al Swary could be leaking into the ground? It is a fair question for any owner here. Al Swary sits at 21.7976, 39.1018, about 29.2 km from the centre of Jeddah, with an approximate radius of 3 km. The centre of the neighbourhood sits about 2 m above sea level, and it is about 5.2 km from the sea coast. Because the land is low and close to the coast, buried tanks in this area deserve a careful check rather than guesswork.

Our inspection for underground tanks begins with a visual and records review of the tank's location, age and any past repairs. Next, the technician checks the access points and the pipework connected to the tank for signs of seepage or wet soil. Where the tank's internal coating is in question, the surface is assessed and the area to be treated is measured, since internal coating is priced at SAR 25–65 per m². The findings are then explained to you in plain terms, with a written note on what was found and what options remain open, so you can decide the next step at your own pace.

To make the visit as smooth as possible, please prepare a few things before the technician arrives. Gather any previous maintenance papers, installation details or repair invoices you have for the tank. Clear the access cover and the area around the tank so the team can reach it safely, and note any recent changes in your water pressure or unexplained damp patches near the villa. Keep the water supply usage stable for a few days beforehand if possible, as this helps the readings reflect the true condition. With these details ready, the inspection can focus on what matters for your villa.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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
• The pump runs for longer periods

Where the problem usually comes from

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

Tools we use in Al Swary

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.
