The city scores highly in areas such as water efficiency, waste water efficiency, e.g., climate adaptation. Nearly 30% of houses in Melbourne have installed rainwater tanks and plans to increase the use of stormwater have recently been published. Energy efficiency of buildings, nutrient recovery (especially phosphate from wastewater), as well as sewage sludge recycling are topics for improvement. A transparent governance structure has been set up in a reaction to the ‘Millennium Drought’ and success has come from many organizations working together to a common goals. This is the secret of Melbourne’s success and can be used as an example for other cities in the world (Van Leeuwen 2014).
