Beykoz Manhole Unclogging

Once the cover is open, the water level in the chamber gives a first idea of how serious the problem is. We clear the outlet pipe with a motorised drain snake, then wash the base and the connected lines with high-pressure water jetting. As the final step we send the camera into the outlet pipe and show you on screen whether there are roots or a break.

In Beykoz, the gradient largely decides where a manhole problem will appear. On steep ground the drain line runs fast, but solids catch at points where the line changes direction or the slope suddenly shifts. In the waterfront yalı houses the fall is very slight, so sediment moves slowly. In the village settlements towards Riva, long lines run through the gardens, and finding the blockage calls for a long-cable camera.

Site managements often contact us because of a smell from the manhole at the car park or garden entrance. In that case we first work out from above which lines feed the manhole and plan the clearing accordingly. In office and plaza buildings in Kavacık, greasy waste from shared kitchens and toilets can build up in the common manhole and slow the drains on the ground floor. In business centres the lines also come together at a single point, so we do not give a firm verdict without a camera inspection.
