Kağıthane Sewer Cleaning

Cantley starts by opening the manholes and inspection chambers and checking the water level and flow direction. No method is chosen until the point where the blockage begins has been seen, otherwise the sediment is simply pushed on to the next section. Where needed, the inside of the pipe is viewed with a CCTV drain camera, and the whole line is flushed section by section with a motorised drain snake or high-pressure water jetting. At the end the flow is checked and the condition of the line is explained to you.

In Kağıthane, the shared stacks of the older buildings on the slopes collect grease and sediment from the upper floors in their lower section. In Gültepe and Çağlayan, the first overflow in ground floor flats often starts at exactly this point. When a building caretaker or site management receives the first complaint from the ground floor, what looks like a problem in a single flat can actually come from the shared stack.

In offices on the valley floor, the kitchenettes and shared toilets are in heavy use during working hours, so blockages tend to start in the middle of the day. In residences, the kitchen and bathroom pipes connect to the stack through a long horizontal run, and sediment builds up easily along it. In buildings with a garden or car park drain, sand and leaves also find their way into the line.
