Ümraniye Manhole Unclogging

For someone living in a student house in Ümraniye, the story often starts with shared use: when several people send grease, wet wipes and hair down the same line, a hard layer slowly forms at the bottom of the manhole. In a dormitory or a flat you have just moved into, nobody knows the history of the line, and the build-up left by earlier users can surface with the first rainfall. So instead of fiddling with the cover yourself, it is better to look first at the level in the chamber and the direction of the line. At Cantley, we first inspect the situation on site and explain the cause, then we clear the drain.

In Atakent and Çakmak, new construction is concentrated in multi-block housing complexes with covered car parks. The wastewater from the blocks passes through the car park ceiling and collects in a shared line, then drops into the site manholes. This line runs a long way and is full of bends, and blockages usually form at the junction at the foot of a block. The first sign is usually drips from the car park ceiling or wastewater overflowing from a cover. In complexes like these, we go through the line plan with the site's technical staff, find the blocked section with the camera, and keep the car park usable.

In Tantavi and Yukarı Dudullu, we come across five- and six-storey older buildings whose plumbing has been renewed piece by piece. When old and new pipes are joined, differences in diameter and a distorted gradient let sediment collect in the line. In the workshops and small businesses of Dudullu, floor drains and staff toilets are heavily used, so the manhole can fill more often. When new buildings put up through urban renewal share the same garden manhole with their older neighbours, the camera is needed to tell which building the problem is coming from.
