The PE Alliance provides owners and engineers alike an avenue to pursue design of polyethylene piping systems and provide specification and installation guidelines which were developed and engineered for and by the polyethylene industry. These calculators, models and installation guidelines are tools directly related to polyethylene piping systems and are current with all existing standards and specifications (eg AWWA, ASTM, NSF, CSA,). The Alliance encourages the design engineer to visit the PPI website at for their great research, writing and presentation of HDPE design tools.
