Üsküdar Sewer Line Renewal

In Üsküdar, the sink in an elderly couple's flat may start draining slowly again after every cleaning. If the office drain in the business centre beneath the same building is connected to the shared line running out to the street, the problem is felt in two places at once. In that case the camera first shows the pipe's crack, broken joint or collapsed section. The decision on renewal is made by looking at this footage.

In older buildings in the historic districts, the internal plumbing has often been renewed, but the connection from the building to the street is still the old clay or cast iron pipe. That is why the blockage turns up not in the flat but in that old section under the garden or courtyard. On narrow, steep streets a vehicle often cannot get close to the address, so the equipment is kept portable.

In waterside districts such as Kandilli and Çengelköy, buildings sit close to sea level, so the line can only be laid with a slight fall. When the weekend load from cafés and restaurants lands on this slow-flowing line, sediment collects at one point. In the newer buildings around Altunizade, wrong waste puts strain on the floor line, so we test the drains connected to it one by one and find which flat is straining the line.
