Underground tank leak detection for villas in Jamaa Al Mlk is best approached by first understanding the location. Jamaa Al Mlk Abdalazyz sits at 21.4931, 39.2464, about 9.4 km from the centre of Jeddah, with an approximate radius of 1.2 km. The area sits about 37 m above sea level according to SRTM open elevation data, and it is about 6.3 km from the sea coast. These facts shape the first checks, since a villa's position relative to the coast and to ground level affects how groundwater and surface runoff may reach a buried tank, so the technician begins with the tank's position on the plot and the surrounding drainage paths.

Several points are left to the site visit, because they depend on conditions that cannot be judged from a map. The technician will inspect the tank's physical condition, its access points, the pipework connected to it, and any signs of staining or dampness around the excavation or the surface above it. The internal condition of the tank, including whether its lining has worn, is also assessed on site. Where a recoating is considered, the cost of tank internal coating is quoted at SAR 25–65 per m², and the actual figure depends on the surface area measured during the visit. Nothing about the tank's real state is assumed in advance.

To help the technician work efficiently, residents should prepare a few details before the visit. Note the tank's approximate size and capacity, the year it was installed if known, and any previous repairs or refills. Mark the location of the fill pipe, vent and pump connections, and tell the technician about any recent changes to the garden, paving or irrigation near the tank. Describe any unusual water bills, odours or wet patches you have noticed. Clear access to the tank cover and the area around it saves time on the day. This information gives the technician a clearer starting point and makes the visit more focused for everyone.

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

The following signs are worth checking before they grow:

• 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 most common causes

• 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.

Tools we use in Jamaa Al Mlk Abdalazyz

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.
