the true price of desal

The only time the true price of desal water will be revealed to Melburnians, is when it arrives on their bills. Only then will Victorians realise they’ve been duped by Brumby and his Ministers into believing the desalination plant is the answer to Melbourne’s water woes.

The Greens know there are much better options for securing water for Melbourne, it rains more in Melbourne than what Melburnians consume. A recent 2007 study found “rainwater tanks are five times more energy efficient that desalination plants…Most Australian houses are suitable for a rainwater tanks…in Melbourne 72% of existing houses have potential for a rainwater tank….fewer than 6% of the houses in Melbourne have water tanks.”

The Greens have a sensible water policy to secure Melbourne’s future water supply. Water conservation, re-use and recycling should be prioritised over energy and capital-intensive strategies such as seawater desalination or long-distance pumping. It is possible for our cities and towns to use a diverse range of water sources including tanks, urban storm water and recycled wastewater, to achieve water supply security and waterway health.

The desalination plant will create 1.2million tonnes of greenhouse gas emissions during operation. It will generate an additional 70,000 tonnes of greenhouse gas emissions from decomposing waste from the plant. It will intake 380,000 small marine organisms per second whilst discharging 8,800 litres of brine per second. Not only is this an economic disaster for the family budget it is an environmental disaster for Victoria’s coastline.

The desalination plant will cost tax payers dearly. Not only in a $5.1 billion construction bill and escalating water costs. It will dump 50,000 tonnes of toxic waste every year and secure big profits for overseas companies - why would we want it?
