Advanced Condition Assessement of Hunter Water's Cast Iron Watermains


Burried assets that form trunk and reticulation water mains form the largest asset group of all major water utilities. As such, considerable resources go into the maintenance, assessment and subsequent predictions on the performance of these resources. As part of Hunter Water's commitment to the Advanced Condition Assessment and Pipe Failure Prodiction Project, the University of Newcastle was invited to a number of recent exhumation sites to collect data for Activity 3 (Corrossion Modelling) of the project. This article détails the procedures used for the collection of accurate corrosion data, in order to quantiify in-situ corrosion losses of in-service ferrous pipes.
