You have talked about capital maintenance being a global issue. In your opinion, what is the "right" level of capital maintenance? That's a complex issue and gets back to data management and having good strategic asset management systems that enable sound investment and decision making. Having the right level of investment in capital maintenance depends on the collection and management of data to enable optimum capital maintenance investment decisions. The right level will vary from authority to authority and depends on the age, conditions, deterioration rates and type of assets, as well as asset criticality and understanding of the risk and consequence of failure. There has been some really great work in the UK and elsewhere on developing new approaches and tools to help us really hone in on the right level of capital maintenance. The water industry in the UK has begun to move from "new build" to "no build" solutions. How have you found the adoption of this approach in Australia? This approach is relatively new to Australia because the focus over the last 10 years has been on the design and delivery of major capital works. The idea of deriving solutions that results in something you don't build, or "sweating the asset", is a new concept here, whereas it has been the case in the UK for a few years now. For instance, it is not uncommon to nd ways to increase the headroom at a treatment works and 'patch up' the existing assets to avoid the need for building a new lane or stage at a treatment works, all while maintaining the level of service to customers. This "no build" approach will become more prevalent in Australia and elsewhere as we push for greater value for money.
