The new economy of multiple scales of solutions are addressed by our ongoing peer reviewed research over the last 20 years and were presented at a WaterSensitiveSA workshop in December 2016.
A busy and interesting week hosting an international delegation and presenting an alternative water plan for Greater Melbourne. Some common themes for sustainability, urban water resources, sustainability and agriculture.
Why the Water Supply Needs a Splash of Competition. Article in the Australian Financial Review on 19 January 2017 by Professor P J Coombes with Michael Smit and Dr Katherine Daniell. Australia’s inefficient water monopoly structure is gouging consumers. It is protected by state legislation and bureaucrats with little appetite for change. What’s needed is a radical overhaul of the business philosophy underpinning water services, to allow improved technology and community-led alternatives to cut water costs.
15 December – 9:30 am, David Spence Room, Level 2, Adelaide Town Hall, 128 King William Street Adelaide. Water Sensitive SA, in association with Rainwater Harvesting Association of Australia, invite you to join a discussion with Professor Peter Coombes who will challenge our thinking about the potential of rainwater and stormwater harvesting to deliver whole of society and system benefits via distributed solutions. We will also explore the myths associated with rainwater harvesting and reuse, and introduce the new Rainwater Harvesting Design Specification. The Planning, Development and Infrastructure Act 2016 together with Living Adelaide the 30 Year Plan Review, offers the best opportunity in more than 20 years to enable stormwater to support a Living Adelaide. Practical tools currently being developed to support industry to maximise the benefits of stormwater harvesting at the allotment scale will be showcased.
Michael Smit and Professor PJ Coombes: An important debate in this country is about the health of people using rainwater, however much of the commentary is research funded by water utilities which has a centralised water distribution perspective quite different to how rainwater harvesting works. One of the recent rebuttal papers by PJ Coombes has just been published and we thought we should discuss some of the issues and assumptions, as much to demonstrate there is a difference of opinion. A presentation at the RHAA seminar in Sydney about widespread use of rainwater and the absence of health epidemics is compelling. Australia has a substantial real world case study with over 2.3 million Australians relying on rainwater for drinking water and more than 6.3 million people using rainwater for some household use. In spite of claims of widespread health concerns, there are no health epidemics or widespread notifications of lead contamination by chief medical officers.
