Abstract

This study examined the durability and reliability of large diameter high density polyethylene (HDPE) water mains (16 in. and larger), as an economical alternative to other pipe materials. The project focused initially on identifying key problems associated with modes, causes, and rates of failure of HDPE water pipelines through a comprehensive literature search. Once these key problems were identified, durability and reliability of these pipes through surveys, experimental work, and case studies were investigated. Research partners: WERF and EPA.
