Reviews existing and proposed accelerated material life testing methods that can be applied to buried PVC pipes. Also examines field performance of PVC pipes that have been in service for 30 to 40 years. Develops life expectancy methodologies to enable utilities to predict the long-term performance of PVC pipes, focusing on the structural, hydraulic, and water quality impact characteristics that can be expected from the long-term use of PVC pipes.
