Is there a way to know whether the underground tank beneath your duplex is leaking before the damage shows up in your water bills or on your ground? For owners in Al Mlk Abdallh, the answer starts with where the property sits. The centre of the neighbourhood is at 24.7324, 46.7414, about 7 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most duplexes here are close enough to the city to be served by the same kind of buried storage that older Riyadh properties rely on. The area also sits about 638 m above sea level, according to SRTM open elevation data, which is useful context for any site survey because ground conditions and drainage can differ from one part of the district to another.

The inspection follows a clear sequence. A technician first reviews the tank's location, its age and any repairs already recorded, then checks the surrounding ground and the pipework that connects the tank to the building. Where a leak is suspected, the tank's condition is assessed for corrosion and cracks on the inside. If the tank needs protection, internal coating is priced at SAR 25–70 per m², so the surface area of the tank is the main figure that will shape the cost. The technician then explains which findings are urgent, which can wait, and what each option would involve, so the owner can decide with a full picture rather than a single quote.

Before the visit, gather a few documents and details that make the inspection faster and more accurate. Note the exact address and the location of the tank if you know it, and mention any recent changes in your water use or any wet patches, soft ground, or unusual smells near the property. Have records of previous maintenance, repairs or coating work, and if the duplex is shared, confirm with the other unit owner that access to the tank area is allowed on the day. Clear the area above and around the tank so the technician can work without delay, and keep a list of questions ready so the discussion covers everything you need to know.

In a duplex, the two floors often share lines, so tests are done floor by floor.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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 most common causes

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

How we choose the tool in Al Mlk Abdallh

The steps in order

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.
