Water pipe is a water supply pipe, while wastewater pipe flushes all the wastewater into sewers. Pipes are generally made of polyvinyl chloride, steel, cast iron, polypropylene and copper. Water and wastewater pipe can be segmented on the basis of product into plastic pipe, concrete pipe, steel pipe, ductile iron pipe and others. On the basis of application, water and wastewater pipe market is divided in five categories: sewer & drain pipe, sanitary sewer, potable water, transmission pipe and others. Plastic pipe segment is expected to show a strong growth in the forecasted period. Despite increased competition from plastics, concrete and ductile, iron pipe is expected to retain largest share of the sewer, drainage, and water transmission markets during the forecasted period.
