Victoria’s new desalination plant will feature a living ‘green roof’ larger than the MCG and the biggest in the southern hemisphere.

Premier John Brumby today announced that local Somerville company Fytogreen had secured a $4.3 million contract to design, install and maintain a landscaped, living green roof on top of the desalination plant in Wonthaggi.

Mr Brumby said construction of the desalination plant green roof would be among the largest coastal revegetation projects in Victoria’s history and would deliver major environmental benefits to communities in the region.

“The living green roof will be planted entirely with local native species, providing a sustainable centrepiece for a project that will secure the future water needs of our state,” Mr Brumby said.

“The roof will house more than 98,000 plants and shrubs, grown from seeds and stock collected locally. A foam resin developed by Fytogreen will be used as an underlay, to store water and nutrients.”

Mr Brumby said Fytogreen expected to hire up to twelve people in the Bass Coast area as a result of the new contract.

“And with plants for the green roof coming from a nursery in Carrum Downs, the local economic benefits from the project are significant,” he said.  

“The desalination project has already brought huge economic benefits to our state, employing more than 3000 people, providing more than $1.1 billion in contracts, with more than three quarters going to Australian companies and two thirds to Victorian suppliers.”

Water Minister Tim Holding said the environmentally sensitive design of Victoria’s desalination plant meant it would be unlike any other desalination plant in Australia, or the world.

“The design of the green roof garden is based on wind testing and water demand modelling and on a scale model that has been growing at Waratah Bay since February 2009,” Mr Holding said.

“The outer edges of the roof will feature a rich tapestry of succulent groundcovers suited to exposure to wind and sun, while small shrubs will grow in the more protected centre area.

Mr Holding said the desalination plant was a sustainable, long-term solution that would secure Victoria’s water needs without having to rely on rain.

“Victorians are doing their bit by restricting water use and our Government is taking the tough decision to invest in projects that will provide water security for future generations,” he said.

“Victoria’s new desalination plant allows us to ease water restrictions and ensures we will not have to put restrictions back again.”

The desalination plant will deliver up to 150 billion litres of water a year to Melbourne, Geelong and some regional communities from December 2011.
