Leak surveys for villas in Al Alya, Riyadh start with the location itself. The centre of Al Alya sits at 24.6931, 46.6845, about 2.5 km from the centre of Riyadh, within an approximate radius of 3 km. Because the district is largely commercial, with shops and offices, many villas here sit close to busy frontages, service roads and mixed-use blocks. Before any equipment is switched on, the technician checks how the villa's supply lines, drainage and boundary walls relate to these neighbouring buildings, since shared services and nearby works can mask or mimic a leak. The site also lies about 622 m above sea level, according to SRTM open elevation data, so the surveyor notes how the water supply reaches the property and whether pressure changes at the rooftop tank or ground-level pump could be affecting readings.

Several things are deliberately left to the site visit. Whether a leak is in a wall, under a slab, in a bathroom floor or in the external network can only be confirmed by listening, pressure testing and, where needed, careful opening of finishes. The condition of the water tank, including its internal coating, is judged on the spot. For reference, tank internal coating is priced at SAR 25–70 per m², but the final scope depends on the tank's size, access and existing damage, all of which are assessed in person. Similarly, the choice between repair, recoating or replacement of a pipe run is made after the survey, not before.

To help the technician, prepare a few points in advance. Note the villa's exact location within Al Alya, including the nearest main road and whether the property faces a commercial frontage. Record when you first noticed damp, a drop in pressure, unusually high meter readings or a change in water taste or colour. Mention any recent works in the building or on neighbouring plots, and say where the water tank and pump are located. Clear access to the roof, the tank room, the bathrooms and the boundary, with the keys or gate codes ready, will let the survey move quickly and keep the findings accurate.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.
