Classification of major cohorts of Australian pressurised cast iron water mains for pipe renewal

Cast iron pipes buried between the 1860s and 1980s still account for a significant proportion of the Australian water transmission network, and failure rates of cast iron trunk mains have risen in the past decades. In Australian cities, the manufacturing methods and corrosion mitigation techniques used in cast iron pipes are strongly correlated with the pipeline burial year. This paper introduces an approach to summarise the remaining in service...
