Book Description
International experience indicates that PE often exhibits the lowest failure rate of all materials in use. Many failures are due to third-party damage or poor joint preparation rather than failure under normal service loading conditions. While low failure rates should also be expected in the United States, there is insufficient historical data to extrapolate future failure rates. This project develops models to predict the long term performance prediction for PE pipes in the United States. The objectives of this study were to (1) review the current field performance for polyethylene (PE) water pipelines; (2) review U.S. and international standards for PE water pipes; (3) review previous and state-of-the-art test methods and modeling techniques for service lifetime prediction of PE pipelines; (4) identify and measure relevant pipe properties that govern long-term field performance; and (5) develop and benchmark models to predict long-term field performance of PE pipes. The experimental findings from this project demonstrate that the fracture performance of currently available PE materials is significantly improved from previous material grades. This indicates that the future performance of these current PE materials should not be assessed based on previous historical data held by water utilities. The simple equations provided from the physical probabilistic failure model in this study provide water utilities with a basis for estimating future failure rates. This information can be combined with knowledge of cost consequences of pipe failure and used to inform future asset management decisions, such as replacement planning and budget setting.

Book Description
In Europe, Polyethylene (PE) pipes have been used for water transportation since the 1950s and In Australia since the late 1970s, with low failure rates. In North America, PE has been used for water supply since the late 1980s and only on a small scale. To assess the current field performance of PE water pipes, historical failure data was requested from a total of 87 water utilities from the Australia, the UK and the US. While actual failure data was supplied in some cases, the majority of information supplied was anecdotal. Details of this study are reported and discussed. Several areas are identified for future development of the Monte Carlo simulation model: Inherent Defect Size, Loading Conditions, and Generic Failure Rate vs. Age Curves.

Book Description
Published by the Plastics Pipe Institute (PPI), the Handbook describes how polyethylene piping systems continue to provide utilities with a cost-effective solution to rehabilitate the underground infrastructure. The book will assist in designing and installing PE piping systems that can protect utilities and other end users from corrosion, earthquake damage and water loss due to leaky and corroded pipes and joints.

Book Description
President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.
