An Examination of Innovative Methods Used in the Inspection of Wastewater Systems

High-quality investigation and diagnosis is fundamental to the decision-making process and to the development of effective strategies for rehabilitation and replacement of our wastewater systems. This report provides a comprehensive review of the current state of the art of investigation technology for both gravity and force mains. It also reviews data management and interrogation, and a structured approach to investigation of gravity and pressure pipe is suggested. Additionally, this report includes detailed reviews of nine current technologies, providing the information utilities need to determine which technology will serve them best.
