2011 – A Statewide Approach to Benchmarking Dam Safety Risk and Continuous Improvement

Susan Ryanand Siraj Perera

This paper describes the benefits of the statewide risk reporting framework used in dam safety regulation in Victoria and its ongoing development. Key to this approach is a web-hosted reporting system and benchmarking process, established by the Department of Sustainability and Environment in collaboration with the Victorian water industry. This is the first time that such an approach has been used in Australia for publicly owned dams.

Sector-wide reporting on dam safety is central to the objective-based approach used by the Department in the governance and regulation of the water industry. Water corporations submit detailed annual reports on dam safety status. This incorporates ‘self assessment’ against performance criteria based on ANCOLD risk and dam safety management guidelines. These are collated to produce a statewide report of industry-wide results on the progress of dam safety management programs. This benchmarking process is providing a driver for on-going improvement and proving to be an effective tool for regulation of publicly owned dams.

The reporting framework has significantly advanced the understanding of dam safety risk across the water sector, with outputs easily understood by both dam safety practitioners and decision makers. It has improved monitoring and trend analysis of risk management practices, and is informing policy development on demonstration of the ALARP principle and decision-making about appropriate long-term dam safety levels.
