The adoption of asset management within the water sector still varies considerably at present.Approaches used range from those focused on asset condition and performance, to thosefocused on the underlying purpose of owning the assets (i.e. the provision of service at anacceptable level of risk). The level of sophistication also varies ranging from informal,through basic to advanced asset management techniques. Advanced asset managementrequires the use of sophisticated software-based modelling tools. The "Pipeline Asset and RiskManagement System" (PARMS) is a suite of computer-based modelling tools, developed incollaboration with water sector partners in Australia, and designed to assist in themanagement of water distribution networks. A new tool has recently been added to thePARMS suite, PARMS-PRIORITY, which helps water utilities to determine those assets thatshould be rehabilitated to manage cost and improve levels of service. The analysis is based onestimating risk, where risk is calculated by combining failure predictions for pipes with theoutput of cost assessment models. Through this risk analysis, PARMS-PRIORITY assistswater utilities to make pipe renewal and valve insertion decisions. Development ofsophisticated asset management tools such as PARMS, in conjunction with data improvementefforts, will facilitate the adoption of advanced asset management focused on deliveringsustainable solutions. Such tools will thereby help the water sector to meet the challengesassociated with expected population growth, and the need to underpin economic growth andenvironmental quality.
