Plastic Pipes Conference Association # 2004 Milan

High-Density Polyethylene (HDPE) piping systems have been available since 1948. In 1955, ASTM established the Plastics Pipe Committee. In 1978, the American Water Works Association (AWWA) approved HDPE for water tubes that were up to 75mm (3”) in diameter. In 1990, AWWA developed the first edition of the AWWA Standard for HDPE water distribution pipes that range in diameter between 100 mm (4”) and 1575 mm (63”). In 1992, the Indianapolis Water Company, now US Filter, adopted this technology and became one of the first municipalities in N. America. to install water mains using HDPE. In 2004, AWWA is expected to publish a new Manual (M55) to assist municipalities and consultants in the design and installation of PE pipes. This paper will present the properties of HDPE pipes and will compare their performance to other materials as related to environmental protection, seismic resistance, corrosion and chemical resistance, durability and reliability, and applicable Standards and Manuals. Relevant case studies will be presented to demonstrate the use of PE pipe for municipal and industrial clients.
