Al Wrwd sits at 24.7244, 46.6785, about 1.2 km from the centre of Riyadh, with an approximate radius of 2 km. When an underground tank leak is suspected here, the first thing we check is simply where the property sits within that footprint, because it tells us how the site relates to the wider city and which access routes a technician is likely to use. The centre of Al Wrwd sits about 631 m above sea level (SRTM open elevation data), and that height matters for how we think about groundwater and drainage on the plot before any digging begins. Confirming the location and elevation first lets the emergency team arrive with the right expectations.

What is left to the site visit is the part that cannot be judged from a map. The technician will walk the property, look at the tank's position relative to buildings, paving and boundary walls, and check whether there are visible signs of wetness, staining or unusual smell at ground level. Decisions about testing methods, the extent of any excavation, and whether the internal lining needs attention will depend on what is found on the day. Where a tank's internal coating is in question, the quote range of SAR 25–70 per m² is only a starting reference, and the real figure can only be set after the tank has been measured and inspected in person.

To help the technician, please have ready the tank's approximate size and age, any previous repair or lining records, the date you first noticed the problem, and the nearest access point for vehicles and equipment. Note the location of fill pipes, vent pipes and any nearby wells or drainage channels, and tell us if fuel or water levels have changed unexpectedly. Keeping the gate, parking and any security arrangements clear before the visit saves time on arrival. With these details to hand, the team can move from first contact to a practical plan without repeating questions that you have already answered.

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

Signs worth paying attention to

If you notice one of these signs in Al Wrwd, 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

Where the problem usually comes from

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

Tools we use in Al Wrwd

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.
