Predicting the Remaining Economic Life of Wastewater Pipes- Phase II: Development of a Robust Wastewater Pipe Performance Index

The objective of this research was to develop protocols and methods for predicting the remaining economic life of wastewater pipes. The researchers include an analysis of data from participating utilities and develop a robust wastewater pipe performance index that includes physical, operational, environmental, and other parameters for pipe segments and the entire pipe system. Two performance models were developed, a structural and a functional index. The indexes provide asset management practitioners information on remaining asset life, improving the confidence in determining the appropriate repair, rehabilitation, or replacement decisions.
