Fact Sheet No.12 – Data collection at Hunter Water condition assessment sites and initial model calibration

Data collection at Hunter Water condition assessment sites and initial model calibration

Overview

The aim of Activity 3 is to develop models for the description and prediction of the long-term corrosion losses and maximum pit depths of cast iron (and also steel) pipes buried in soil. The approach currently being pursued is to develop a corrosion model based on corrosion fundamentals and on documented field observations. The models will describe the amount of corrosion as a function of exposure period and the main influencing external soil conditions. Field data has recently been collected at a number of condition assessment sites within Hunter Water Corporation’s network, and this data was used to calibrate an initial model for pipes buried in clay soils. A summary of this work is presented in this fact sheet. More details on this work are presented in Petersen et al (2013).

Information about Pipes

In August 2011 international water research organisations, Australian water utilities and three Australian universities came together through a collaborative research agreement, and committed overall funding of $16 million (including $4 million cash) over five years to undertake this research through the Advanced Condition Assessment and Pipe Failure Prediction Project.
