Drain and sewer leaks in Al Shmysy villas are often first traced to the ground itself. The district's centre sits at 24.6238, 46.7000, about 10.3 km from the centre of Riyadh, with an approximate radius of 1.2 km, so most homes here share a similar local setting. The centre of Al Shmysy sits about 587 m above sea level (SRTM open elevation data), and the nearest wadi channel is about 1.4 km from the centre of Al Shmysy (OpenStreetMap). Because of this, our technicians begin by checking where the main drain runs in relation to the plot slope, and whether surface water or heavy runoff could be reaching the underground lines after rain. Checking the fall of the drain and any signs of soil movement around the inspection chambers comes first, since these are the quickest clues to why water is pooling or backing up.

Several things can only be judged on site, and we leave them to the visit. The technician will decide whether a camera survey is needed, how far the damage extends along the line, and whether a section of pipe can be repaired or must be replaced. They will also assess the condition of any water storage tank if it is connected to the fault, including the state of its internal lining. Where a tank coating is considered, the typical range is SAR 25–65 per m², but the final area and scope depend entirely on what is found, so no figure is fixed until the inspection is complete. Access, the depth of the lines and the layout of the villa's existing fittings also shape the approach and are confirmed in person.

To help the technician arrive prepared, please note when the problem first appeared, whether it worsens after rain or heavy use, and which fixtures drain slowly. Mark the location of any manhole covers, septic or collection points you know of, and share any previous plumbing drawings or repair records for the villa. Photographs of damp patches, cracks in paving near drains, or water stains on walls are also useful. Keep the area around the inspection points clear and make sure someone who knows the property is available at the appointment. This information lets the visit focus on diagnosis rather than discovery, and it shortens the time before a clear plan for the repair can be agreed.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

When do you need drain & sewer leaks?

These are the signs most often linked to drain & sewer leaks:

• Sunken tiles above a drain line
• A persistent sewage smell
• Slow drainage that keeps coming back

The most common causes

• A common cause: a broken buried drain pipe.
• A separated joint — we check this before anything else.
• Roots or build-up inside the line — we check this before anything else.

Tools and methods, and when we use them

From the first visit to the report

1. Inspection chambers: We open the chambers to see the flow and the condition.
2. Line camera: A camera goes through the open line to find breaks and blockages.
3. Dye test: Dye confirms where water leaves the line.
4. Recommendation: Local repair or line replacement, with the camera images.
