Hinchinbrook Shire Council is looking at improving its policies and procedures and part of this includes its asset management plans. One way being investigated to improve asset management plans and how HSC carries out its asset maintenance is through a criticality analysis. A criticality analysis will allow HSC to identify its most critical infrastructure to ensure adequate maintenance is carried out on an asset or refurbishment/replacement is carried out. This aim of this dissertation is to perform a criticality analysis on HSC’s water and sewerage assets.

Asset data for HSC’s water and sewerage assets was collected and criticality factors and severity scoring were developed. Based on asset data, the criticality factors and severity scoring the assets received a criticality rating. A model was constructed in Microsoft Excel to process the data and automatically carry out calculations for each asset. Once the calculations were completed each asset would have received a criticality ranking which could be used to determine HSC’s most critical water and sewerage assets and help in making asset management decisions.

Over 2500 assets were then analysed using the calculator with 98.4% of assets being identified as non-critical, 1.5% as semi critical, 0.1% as critical and no assets as highly critical. These results are relatively accurate of the assets however some improvements could be made to get a better representation of the assets and show a better spread amongst the different criticality rankings.

The results show that the criticality framework constructed as part of this investigation can be used by HSC to help make asset maintenance and replacement decisions and with further work and refinement could be expanded to incorporate more of Council’s assets.
