My underground tank in Al Msana may be leaking, what should I do first? If you suspect a leak, act quickly rather than waiting for the problem to show above ground. Al Msana is a residential district in Riyadh, close to the centre of the city, at roughly 24.5789, 46.7300. It lies about 16 km from central Riyadh and covers an approximate radius of 1.2 km. The area sits at around 572 m above sea level, and the nearest wadi channel runs about 0.4 km from the centre. Because the ground here can carry runoff from wadi channels, any fuel or water that escapes underground can spread further than you might expect, so an early inspection matters.

Our emergency team handles underground tank leak detection across the district. The visit starts with a check of the tank and the surrounding ground to confirm where the problem is coming from. The inspector then looks at the internal condition of the tank. Where coating is worn or damaged, the cost of recoating is typically in the range of SAR 25–70 per m², and the inspector will measure the affected surface so you receive a clear estimate before any work begins. You will be told what was found, what needs repair, and which steps are urgent, in plain language.

Before the visit, gather the records you have for the tank, including its installation date, any previous repair or coating work, and a note of when you first noticed a smell, wet ground, or a drop in stored fuel or water levels. Keep the area around the access point clear so the inspector can reach the fill and vent points safely. Do not try to open the tank or dig near it yourself. Turn off any pumps connected to it and avoid using nearby ignition sources until the inspection is complete. Having this information ready will help the team reach a diagnosis faster and keep your costs and disruption to a minimum.

If water is flowing, close the main valve first, then call or message with photos.

How we choose the tool in Al Msana

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.
