Underground tank leak detection in Al Farwq: the local context

The centre of Al Farwq is at 24.6494, 46.7786, about 12.6 km from the centre of Riyadh, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. Main roads in or near Al Farwq: Madinah Road, Al Nahda Street, Asad Al Sunnah Road.

The centre of Al Farwq sits about 624 m above sea level (SRTM open elevation data).

Underground tanks on rest houses and farms most often fail quietly. A slow seep through a cracked joint, a corroded fitting or a tired internal coating can drain water for weeks before anyone sees a drop on the gauge. In Al Farwq, the place name is the first thing to keep in mind: the centre of Al Farwq sits about 624 m above sea level (SRTM open elevation data), and it lies about 12.6 km from the centre of Riyadh, so the ground and the water demand around a property here are not the same as in a low-lying city district. Our approach starts with a plain question: is the loss real, and where is it happening?

The local setting changes how we work. The centre of Al Farwq is located at 24.6494, 46.7786, with an approximate radius of 1.2 km, which means properties here often sit well apart from one another and from the main supply network. For a farm or rest house that relies on its own tank, that distance means a leak is harder to hide behind a neighbour's meter or a shared pipe. We therefore compare the tank's readings with the property's actual use over several days, check the pipework that runs between the tank and the buildings, and only then decide whether the tank itself needs attention. Where the internal coating is the issue, the cost is usually framed as tank internal coating at SAR 25–70 per m², so the size of the tank drives the final figure more than anything else.

Before the visit, ask the provider a few direct questions. Ask how they confirm a leak before recommending any repair, and whether they will show you the readings rather than only a verdict. Ask which parts of the tank and its connections they will inspect, and how the coating cost will be measured per square metre for your specific tank. Ask what they need from you in advance, such as the tank's age, its capacity, recent usage and any past repairs. A clear answer on each point tells you whether the visit will be a real diagnosis or simply a sales call.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

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

Causes we see in the field

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

How we choose the tool in Al Farwq

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.
