I have just send this letter in to Premier John Brumby. It will be interesting to read his answer, although I suspect I won't get one.
You stated on ABC 774 radio on Thurday 26 June 2008 that "the proposed Wonthaggi desalination plant would use less power than equivalent rainwater tanks"
Can you please provide evidence for this claim?
Studies of water tanks have shown that they would use one fifth of the power of the desalination to supply the equivalent amount of water (150 gigalitres).
I have a power meter on our rainwater tank pump on our house so I will provide you with more empirical data on this next week to confirm this data.
Information about the plant and why rainwater tanks would be a better option is available in this article: http://www.greenlivingpedia.org/Victorian_desalination_plant
I look forward to your timely response to this very important question.
