John Brumby and Tim Holding would do well to consider mandating rainwater tanks for new houses rather than building an energy guzzling desalination plant.
Our domestic water tanks have supplied over 95 per cent of the water for our Surrey Hills house since we installed them in 2001. Based on our experience, 600,000 households could save up to 160 gigalitres of water per year by using captured rainwater and reducing their daily consumption. The energy our pump uses would multiply to 140 kWh of energy per day for these same households. The proposed desalination plant would consume 15 times as much energy just to operate.
There would also be significant emissions associated with the construction of the plant, the pumping of water to Melbourne and waste decomposition and transport.
Domestic water tanks would be a much cheaper, more effective, more greenhouse friendly and more popular solution to meeting Melbourne's water needs than either the proposed desalination plant or the north south pipeline projects.
