California American Water's Ventura service district includes approximately 20,000 households and businesses, thereby supplying water to approximately 60,000 people in the cities of Camarillo, Newbury Park and Thousand Oaks.
PPI offers new engineering design tool
It is now easier to design and write high-density polyethylene pipe (HDPE) into a specification or respond to an RFP for a buried potable water system by using a new guide developed by the Plastics Pipe Institute Inc. (PPI). Issued in December 2009, Model Specification MS-3/2009 provides design engineers, public works directors and others, including city officials, with an easy to follow template that includes authoritative references that can be included in a design, an RFP or other documentation for a project.
"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."
MS-3/2009 is available as a free download at the PPI website, 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.
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.
"The document came about because we have had engineers and officials, such as mayors of cities, city council members and others, ask for an overview that would explain what is required for the use of HDPE pipe in a typical potable water system," he continued. "They realize that old metal and cast iron pipes are cracking and costing untold water losses, and HDPE provides the economical and practical solution. This model spec gives them the knowledge to make an informed decision for a viable, long-lasting solution for fixing the quickly failing underground infrastructure."
