A length of conduit, manufactured from various materials and in various lengths, that when joined together can be used to transport wastewaters from the points of origin to a treatment facility. Types of pipe are: Acrylonitrile-butadiene-styrene (ABSAcrylonitrile-Butadiene-Styrene; a form of thermoplastic.); Asbestos-Cement (ACAsbestos Cement; a composite material used in pipe construction.); Brick PipeA long tube of clay, concrete, steel, metal, wood, etc., for conveying water, gas, oil or other materials. (BP); Concrete Pipe (CP); Cast Iron Pipe (CIPCast Iron Pipe); PolyethyleneA ductile, durable, virtually inert thermoplastic composed by polymers of ethylene. It is normally a translucent, tough solid. In pipe grade resins, ethylene-hexene copolymers are usually specified with carbon black pigment for weatherability. (PEPolyethylene; a form of thermoplastic pipe.); Polyvinylchloride (PVCPolyvinyl Chloride; a form of thermoplastic pipe.); Vitrified Clay (VC).
