In 2014, the total replacement value of the 3 waters assets in New Zealand was estimated to be about NZ$45.2 billion. As these assets are upgraded or replaced, many difficult decisions will need to be made in respect to the trade-offs between Levels of Service, capital costs, operating costs and management of risk. The aim of this project is to provide guidance and tools to enable New Zealand Water organisations to implement advanced asset management processes to develop inspection, maintenance and renewal strategies for pipework in potable water, waste water and storm water systems.
