Underground tank leak detection in Ghrnata: the local context

The centre of Ghrnata is at 24.7912, 46.7437, about 11 km from the centre of Riyadh, with an approximate radius of 2.8 km. The service-area circle on the map below is drawn from this point. Ghrnata is mainly villas.

The centre of Ghrnata sits about 617 m above sea level (SRTM open elevation data). Main roads in or near Ghrnata: Dammam Road, Eastern Ring Road, Eastern Ring Road.

Ghrnata sits roughly 11 km from central Riyadh, and its streets are shaped largely by villas, which means many restaurant sites here are older compounds where tanks were installed in gardens, service yards, or beside parking areas. The neighborhood is also bordered by the Dammam Road and the Eastern Ring Road, so traffic and heavy vehicle movement near the site can add vibration and surface loading to buried structures. Elevation at the site is about 617 meters above sea level, which is a useful reference when the team reviews groundwater behavior and drainage paths around the tank.

For a restaurant tank, the first checks focus on the tank shell, inlet and outlet pipework, and the ground directly around the tank, since leaks often start at joints or where soil has shifted under traffic loads. Because villas tend to have mixed-use surfaces above tanks, the team looks at whether the cover, access points, and nearby paving have settled or cracked. The sequence matters: confirming the tank's condition before testing the surrounding soil prevents misreading a surface problem as a leak.

Before the visit, gather the tank installation date, any past repair records, recent fuel or wastewater volume trends if available, and a sketch showing the tank position relative to the building and driveways. Ask the team how the test will be run, whether any part of the tank must be emptied, and what interior lining options exist after detection, including typical cost ranges per square meter for lining from inside the tank, which typically falls between 25 and 65 riyal per square meter.

For restaurants, visits are planned outside service hours and recorded for the premises file.

When do you need underground tank leak detection?

These are the signs most often linked to underground tank leak detection:

• 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

Causes we see in the field

• Construction joints and corners.
• 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 Ghrnata

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.
