1.1.1 Market Share of HDPE Pipes in United States In a study by the Plastics Pipe Institute2 (2009), it was reported that while HDPE pipes have been used for municipal water applications for almost fifty years, they are still minimally used for potable water transmissions/distributions and wastewater services when compared to other types of pipe. Steel pipes, Polyvinyl Chloride (PVC) pipes, Ductile Iron (DI) pipes, Fusible PVC pipes, and Prestressed Concrete Cylinder pipes (PCCP) are other pipes that are used for municipal applications.
