PPI Releases Model Spec for HDPE Pipe in Buried Water Systems
The Plastics Pipe Institute, Inc. (PPI) has developed a new guide to help design engineers, public works directors, and others design and write high density polyethylene pipe into a specification or respond to a request for proposals (RFP) for a buried potable water system.
"To prepare a specification or to fulfill an RFP for a buried potable water project, the proper facts must be collected and included," stated Tony Radoszewski, executive director of the PPI. "This model spec contains that information as well as many references to other standards that can be used in support of a project."
The guide is available as a free download at the PPI Web site, www.plasticpipe.org, by clicking on the "Literature" tab and selecting "Model Specifications." The document includes sections on system design parameters, pressure class charts, pipe, fittings, joining methods and installation.
"Municipalities came to the PPI requesting a document that would provide a step-by-step plan which could be followed for designing and installing a potable water system using HPDE pipe. More and more towns and cities want to write design specifications in order to take advantage of HDPE pipe. We designed this latest model spec to be an easy to understand technical document," Radoszewski said. "A layperson can read and understand it in just a few minutes. And it provides supporting references and the industry standards that could be required.
PPI is a Texas-based, non-profit organization, founded in 1950, that is the major trade association representing all segments of the plastic piping industry.
