Buried line leaks in Jeddah: before buying or handover

What is specific about Jeddah for buried line leaks

Team note on Jeddah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).

Jeddah is about 2 km from the sea coast (OpenStreetMap).

Is a buried water line leak something you need to check before buying or taking over a property in Jeddah? The short answer is yes, and the local geography is part of the reason. The centre of Jeddah sits about 15 m above sea level, and the city is about 2 km from the sea coast. That combination means that pipes, tanks and drainage in many areas run through ground that is not always stable or predictable, so a leak can go unnoticed for a long time. Treating a buried line as an unknown rather than a safe assumption is the sensible starting point for any sale or handover.

When an inspection is arranged, the work usually begins with the visible parts of the system and then moves underground. Start by checking the meter, the main isolation valve and any water tanks on the roof or at ground level. Look for damp patches on walls and floors near where pipes enter the building, staining on boundary walls, and soft or sunken ground in the garden or driveway. Listen for water flowing when all taps are closed, and note how the meter reads over an hour with no water in use. If the meter moves when nothing is running, that is a clear signal to investigate further. For tanks, check the internal condition as well, since coating work on tank interiors is priced per square metre, in a range of SAR 25–65 per m², so the size of the tank affects the cost of any repair.

Before the visit, gather what you can so the inspector has a clear picture. Collect the property's water bills for the past year, any previous repair records, and the layout plan showing where the main supply line runs. Note any problems you have already seen, such as low pressure, discoloured water or a history of damp. Clear access to the meter, the tanks and the garden area in advance, and ask the seller or landlord to confirm who is responsible for underground work. A well-prepared visit saves time and gives you a clearer basis for negotiating the price or agreeing responsibility before you sign.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs that call for buried line leaks

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

• The meter turns while everything inside the house is sound
• A permanently green or muddy patch in the yard
• Sinking interlock paving

Causes we see in the field

• A common cause: a joint under the interlock paving.
• A common cause: a broken irrigation line.
• A common cause: the supply line from the meter to the tank.

How we choose the tool in Jeddah

How the work is done, step by step

1. Isolating the line: The buried section is separated from the house network.
2. Pressure test: The line is checked for pressure loss.
3. Tracer gas: A safe hydrogen–nitrogen mix escapes at the leak and is detected at the surface.
4. Recommendation: The proposed excavation point and its size.
