Build level of services and customer value into decision making: Sydney Water's water main asset management strategy*

摘要

Sydney Water's water network consists of about 21,000 km of water mains. Sydney Water is a statutory state owned corporation, with the Independent Pricing and Regulatory Tribunal as the economic regulator. Sydney Water has developed a comprehensive set of decision frameworks and business processes to manage the life cycle of water main assets to achieve a desired level of service and financial return within an acceptable risk. With the current constrained financial and economic environment, affordability is the most pressing issue in the water industry as customers are seeking value for money. It is requiring the water industry to reduce capital investment programs and deliver more with less while maintaining or improving customer satisfaction. This paper presents the analysis of the asset performances and customer expectations against the level of services and explains how Sydney Water explores the opportunities to build the level of services and customer value into its asset management strategy and decision framework to optimise the capital investment programs.
