Renewal Engineering Technologies for Drinking Water and Wastewater Pipeline Systems - A State of the Art Literature and Practice Review

Abstract

Over the last few years, several advancements have been made in water and wastewater pipe renewal technologies that have allowed utilities to utilize innovative renewal techniques that decrease project costs, the impact of the project on the surrounding citizens and environment, and allow for expedited pipeline renewals compared to traditional open trench methods. The challenge now is in getting utilities to implement new innovative technologies within their system. This thesis provides background information on a number of the technologies available for the renewal of water and wastewater system pipelines. It then provides State of the Art Literature and State of the Art Practice Reviews based on technology use trends in literature and technology use trends in utility practice. The information from both reviews is then synthesized to provide a clear view of the state of the water and wastewater pipeline renewal technology industry, including the trends by pipe material, drivers for renewal, and technology type.
