The article reports on a research study which develops a forecasting system to analyze the service life and performance expectations of polyethylene (PE) pipe in potable water pipe systems in the U.S. Findings reveal that the projected lifetime of exhumed pipe samples across a variety of geographic areas is more than 100 years. It indicates that utility satisfaction rates for post-1990 installed PE were ranked at 95% and 93%.
