Underground tank leaks in Al Nhda, Riyadh usually begin with a slow loss that is easy to miss: a drop in stored volume, a damp patch near the fill point, or a sudden rise in water bills. In emergency cases, the most common cause we see for this property type is corrosion of the steel shell or fittings that lets fluid escape into the surrounding ground, often unnoticed for weeks. Our first step is to confirm the source before any repair is planned, so that the response matches the actual problem rather than a guess.

Al Nhda sits at about 24.7608, 46.8061, roughly 14.2 km from the centre of Riyadh, within an approximate radius of 1.2 km. Its centre sits about 596 m above sea level, which is a useful reference when technicians check tank levels, pipe gradients and drainage paths on site. Because the district is set apart from the city centre, we plan travel time and parts access in advance, so that an emergency visit starts with the right equipment rather than a return trip. Where a tank needs its inside protected after repair, internal coating is priced at SAR 25–70 per m², and the final figure depends on the tank's size and condition, which we confirm during the inspection.

Before the visit, ask the provider for the exact location of the tank and its approximate capacity, and whether the team will test for leaks before recommending any digging or replacement. Also ask how they will record findings, what they will do to protect people and property while the problem is isolated, and whether the quote will separate detection, repair and coating costs. Clear answers to these points help you judge the response quickly, which matters most when a leak is already causing damage.

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

Signs that call for underground tank leak detection

The following signs are worth checking before they grow:

• A noticeable drop in the water level overnight
• The pump runs for longer periods
• The tank needs refilling faster than usual

Causes we see in the field

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

Tools we use in Al Nhda

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.
