Abstract

This project (1) developed an analytical approach and guidelines for selecting pipe rehabilitation methods, based on full non-destructive examination (NDE) scans of a cast iron or ductile iron water main; and (2) showed how an NDE tool can be used economically, as part of a rehabilitation project, to optimize the rehabilitation. Research partners: EPA and WERF. Published in 2015.
