What is specific about Al Mhmdya for hidden water leak detection

The centre of Al Mhmdya is at 21.6495, 39.1253, about 12.8 km from the centre of Jeddah, with an approximate radius of 2.9 km. The approximate area shown on the map is centred here. Al Mhmdya is about 2.4 km from the sea coast (OpenStreetMap).

The centre of Al Mhmdya sits about 6 m above sea level (SRTM open elevation data). Main roads in or near Al Mhmdya: Madinah Road, Al Nuzhah Street, Prince Sultan Road.

Hidden water leaks in villas usually show up first as a sudden jump in the water bill, damp patches on ground-floor walls, or a faint hollow sound under tiles, yet the source is often a pipe buried in the slab or a tank that has been losing water for months before anyone notices. In Al Mhmdya, villas often rely on rooftop or ground-level storage tanks, so a leak in the tank wall or its fittings can go unseen for a long time. Our detection work starts with the most likely routes for water to escape and then narrows down to the exact point using listening equipment and pressure checks, rather than opening walls at random.

Al Mhmdya sits at the centre coordinates 21.6495, 39.1253, roughly 12.8 km from the centre of Jeddah, and its centre lies about 6 m above sea level. Those facts matter for how we work. A site that is only a short drive from the coast and close to the sea surface can carry higher salt content in the ground and in older concrete, which can speed up corrosion of metal pipe fittings and tank linings. Because the area covers an approximate radius of 2.9 km, many villas here share similar construction and similar water supply arrangements, so the pattern we look for is familiar. Being about 2.4 km from the sea coast also means that salt-laden air can affect exposed fittings and roof access points, and we check these as part of the walk-through. Where a tank is found to be deteriorating, the internal coating is priced at SAR 25–65 per m², and we explain the surface area involved before any work is recommended.

Before the visit, ask us a few plain questions so the appointment is useful. Tell us the approximate age of the villa, where the tank and pump are located, and whether the water bill has risen recently. Let us know if you have noticed damp on walls, uneven floors or a constant sound from the pipes at night. Ask how the detection will be carried out, what will be checked first, and whether any finding will require opening a surface. Confirm the expected surface area of the tank so the coating estimate can be prepared in advance. A clear picture of these details lets the technician arrive ready and keeps the visit focused on your villa.

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

Signs worth paying attention to

These are the signs most often linked to hidden water leak detection:

• The meter keeps turning with every tap closed
• A water bill higher than usual with no change in use
• A damp patch that slowly grows on a wall or ceiling

Where the problem usually comes from

• A common cause: a corroded joint inside a wall.
• A cracked pipe under floor tiles.
• A hot line that expands and contracts with use.

Tools and methods, and when we use them

The steps in order

1. Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
2. Line isolation: We close valves one line at a time to see which line loses pressure.
3. Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
4. Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
5. Documentation: Readings, photos and the likely position go into a written report.

What we advise against

• Repainting the stain while the moisture keeps coming back
• Breaking tiles at random before the line is identified
