Book excerpt: Plastic pipe has been used for many decades in water and sewer applications. More recently, plastic pipe has been used in new embankment dam construction and in the renovation of existing conduits. However, most of the available design information is targeted toward water distribution and sewer pipes and does not address the unique factors involved in using plastic pipe in embankment dams. In general, information on plastic pipe is too dispersed for the best use of lessons learned from past performance, and compilation of information into a more readily available source was needed. Due to the absence of any single recognized standard for plastic pipe used in embankment dams, there is significant inconsistency in the design and construction rationale. In an effort to deal with this problem, this document has been prepared to collect and disseminate information and experience that is current and has a technical consensus. The goal of this document is to provide a single, nationally recognized standard to promote greater consistency between similar project designs, facilitate more effective and consistent review of proposed designs, and result in increased potential for safer, more reliable facilities. This document is intended to supplement the plastic pipe information in the Federal Emergency Management Agency's (FEMA) Technical Manual: Conduits through Embankment Dams (2005). This document provides in-depth analyses of loading conditions, structural design, and hydraulic design of plastic pipe. This document attempts to condense and summarize the body of existing information, provide a clear and concise synopsis of this information, and present a recommended design approach. The authors reviewed most of the available information on plastic pipe as it relates to use within embankment dams in preparing this document. Where detailed documentation exists, they cited it to avoid duplicating available materials. The authors have strived not to reproduce information that is readily accessible in the public domain. Where applicable, the reader is directed to selected portions of FEMA's Technical Manual: Conduits through Embankment Dams (2005) and other consensus-accepted references for additional guidance. This document is intended for use by personnel familiar with embankment dams and conduits, such as designers, inspectors, construction oversight personnel, and dam safety engineers.
