Book excerpt: In 2006, WERF initiated a program of research to assist water and wastewater utilities to improve strategic management of their pipelines, treatment works, and other physical assets. This report is an output of the fourth research track (Track 4) of WERF’s research program ‘Strategic Asset Management Communication and Implementation’ (SAM1R06).The goal of Track 4 is to contribute to the development of techniques, tools and methods for estimating residual life of wastewater assets. This report provides a synthesis of knowledge on available methods to estimate “end of life” and “remaining asset life.” Drawing on the literature and the knowledge of the research team and industry partners, information is presented on the factors that influence the life of the different asset classes involved in the provision of wastewater services. A taxonomy of asset life is given, along with a critical review of the conceptual linkages between risk, asset management, and remaining asset life. A review of techniques used to assess remaining asset life is included, as well as a detailed ‘state of the art’ review of modeling tools and approaches. One of the key questions to be addressed in this initial stage of the research was the state of knowledge for estimating and predicting remaining asset life, and the capacity to translate between condition and performance data (e.g., the presence of significant defects) and the residual life of an asset. In this regard, this report builds on previous work undertaken by the research team into protocols for condition and performance assessments, as detailed in WERF (2007).
