Before we start: what we know about Al Rfyaa

The centre of Al Rfyaa is at 24.6399, 46.6616, about 8.3 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. The nearest wadi channel is about 0.8 km from the centre of Al Rfyaa (OpenStreetMap).

The centre of Al Rfyaa sits about 618 m above sea level (SRTM open elevation data). Main roads in or near Al Rfyaa: Prince Faisal bin Fahd bin Abdulaziz Road, Prince Talal bin Abdulaziz Road, Prince Sattam bin Abdulaziz Road.

Imagine a homeowner in Al Rfyaa whose villa has a buried water or fuel tank that has sat quietly in the garden for years. One day the monthly bill rises, the pump runs more often than it should, or a damp patch appears on the ground near the tank. Nothing looks obviously wrong, yet the owner suspects something is leaking underground and wants to know what checking it would involve and what it might cost.

The local facts matter here. Al Rfyaa sits at roughly 24.6399, 46.6616, about 8.3 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most properties are a reasonable drive from the city core and a service visit needs planning around travel time. The area lies at about 618 m above sea level, and the nearest wadi channel is about 0.8 km from the centre, which means that when rain falls, water can move across the ground and collect near low points. For a buried tank, that combination makes it worth checking whether surface water, soil moisture or runoff could be masking or worsening a leak, rather than assuming the problem is inside the tank alone.

A practical sequence starts with observation. Record your meter readings, note any wet patches, unusual smells or changes in pump behaviour, and check whether the ground around the tank stays soft after dry weather. Next, arrange an inspection that tests the tank and its pipework, and ask the provider to explain whether the findings point to a leak in the tank wall, a fitting or the surrounding pipework. If the tank needs repair, ask for the surface area to be measured, because internal coating is usually priced at SAR 25–65 per m², so the size of the tank directly shapes the total. Finally, request a written quote that lists the scope, the method and any drainage work near the site, then compare it against your recorded readings before agreeing to the work.

Signs worth paying attention to

If you notice one of these signs in Al Rfyaa, it is a good moment to talk to the team:

• Damp or salt marks on the tiles above the tank
• The tank needs refilling faster than usual
• The pump runs for longer periods

Causes we see in the field

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

How we choose the tool in Al Rfyaa

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.
