Distribution water mains are a critical component of water supply networks and the integrity of these pipelines can affect the water supply to a large percentage of a city's population。 The West Derwent Pipeline is one of the main distribution pipelines into Hobart and it supplies approximately 60% of the metropolitan water demand。 Hobart Water， the owners and operators of this pipeline， has a responsibility to the community to ensure the continued supply of water to Hobart。 Towards this goal， in 2004， Hobart Water began the process of developing a long term Asset Management Strategy Plan for the longevity of this pipeline system。The Asset Management Strategy Plan was developed for the West Derwent pipeline system after reviewing all available historical performance data， assessing the current condition of the pipeline， and determining the probability of failure and the risk exposure for each subsection of the pipeline。 The unique process of optimised decision making (ODM) analysis was the tool used for determining the most cost effective strategy for the management of this pipeline。 All data gathered during the condition assessment of this pipeline， including the extensive field investigation was captured in a GIS system to provide a central database for future visual reference and performance data， and historical comparison。
