My underground tank might be leaking. Who do I call in Syah, Riyadh, and how fast can someone come? Syah sits at about 24.6073, 46.7022, roughly 12.1 km from the centre of Riyadh, and the area we cover extends in an approximate radius of 1.2 km from that centre point. Because the district lies about 579 m above sea level and the nearest wadi channel runs roughly 0.4 km from the centre, ground conditions and drainage can vary from one street to the next, so a leak check should start with knowing exactly where your tank sits on the property.

When you request an emergency visit, the technician first confirms your address against the Syah area boundary and records the tank's location, size and fill history. The inspection then moves in clear steps: the tank and fill lines are checked for visible signs of seepage, the inventory readings are reviewed for unexplained loss, and the ground around the tank is examined for wet patches, odour or staining that could show where fluid is escaping. Where a leak is confirmed, the report sets out the affected area so that repair options and the cost of tank internal coating, quoted at SAR 25–70 per m², can be discussed on the basis of the actual measured surface rather than an estimate.

Before the technician arrives, gather a few things to speed up the visit. Note when you first noticed the problem, such as a drop in fuel levels, a smell near the tank, or damp soil, and keep any delivery receipts and past inspection records. Clear access to the tank cover and the surrounding ground, and make sure someone who knows the property is available to let the team in. Keep the area free of vehicles, and do not attempt to pump out or open the tank yourself, since that can make the leak harder to locate and the situation less safe.

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

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
• The pump runs for longer periods

Causes we see in the field

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

Tools and methods, and when we use them

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.

What we advise against

• Waterproofing the tank before confirming the loss is from the tank and not the line
• Ignoring the float valve
