This research was performed in order to compile and better understand the state of the technology for drinking water pipeline condition assessment methodologies and technologies, focusing primarily on the U.S. The researchers performed literature reviews and direct data mining from utilities participating in the project. The report includes a sample case study which discusses the Philadelphia Water Department’s (PWD) use of tethered, in-line acoustic technology for detection of leaks in their large diameter water transmission lines. The report proposes a standard data structure for utilities to use for reporting purposes when performing condition assessment work on drinking water pipelines. Published by WERF. 206 pages.
