7 Context for what is happening in the water industry Climate shift 70%. yields are collapsing dramatically, 30% to Rapidly growing populations and changing demographics. Additional environmental flows for stressed rivers. Expectations of increased levels of service i.e. growing affluence. Meeting these challenges in a sustainable manner e.g. water/energy inter-relationships and operating in a carbon constrained world.

16 National Energy & Greenhouse Gas Reporting Scheme Carbon Pollution Reduction Scheme Offsets policy Maximising the production of renewable energy Energy efficiency

17 Water: Multiple sources of water Management of water grids Potentially non-utility suppliers of water Water supply catchments more vulnerable to wild fire New sources of water more expensive & energy intensive Complexity of treatment processes increasing Emerging contaminants of interest

18 Wastewater: Flows in decline Will sewers & stormwater be always separated in the future? Water recycling yields under pressure Odour/corossion Wastewater plants as green power stations Source control in an era of recycled water Minimisation of fugitive emissions Complexity of treatment processes increasing

19 How do we optimise these new systems from a sustainability perspective? Training & skills development introduced? will a national standard be Implementing sustainable asset management Compliance with National Drinking Water Guidelines and Recycled Water Guidelines More onerous reporting requirements and water utilities subject to community and stakeholder scrutiny like never before Technological breakthroughs nano-particles

20 Despite the challenges the industry is in good shape Operators at the front line have a pivotal role Climate change is the X factor Training, research and collaboration is the key to managing complexity
