uPVC drainage pipe
uPVC drainage pipes are primarily used for discharging wastewater underground from a building to the public sewer system. These plastic pipes are produced in different nominal widths. These pipes can be recognised by their orange-brown colour, which clearly distinguishes them from the grey PVC wastewater pipes, which are suitable for high temperatures. The pipes are made of unplasticised polyvinyl chloride (uPVC) and are exclusively intended for the discharge of wastewater below ground to the sewer system. Source of German text: Wikipedia
