What is a waste pipe

The waste pipe is part of the internal drainage system.  Discharges waste water through sewerage to public sewage or sewage treatment plant. The individual parts of the waste piping are divided into sloping connecting pipes, vertical and laid waste pipes. The sloping connecting pipe is connected to a device from which waste water is diverted to other sewerage areas. 

Waste piping is made of polypropylene, PVC, polyethylene, or materials such as stainless steel, waste alloy or stoneware.
