industry news regular features 18 AUGUST 2012 water Western Water's Carbon-Neutral First Toolern, a new residential development north-west of Melbourne that aims to be Australia's first water- neutral suburb, will rely on Australia's first certified carbon-neutral recycled water plant. Low Carbon Australia's CEO Meg McDonald visited Western Water's Class A Recycled Water Plant at Melton to meet Western Water's new Managing Director Neil Brennan and present the plant's carbon neutral certification in July. Ms McDonald congratulated Western Water on reducing the plant's carbon footprint by just under 75 per cent by installing a cogeneration unit that uses methane emissions generated from the water recycling process to power the plant. To achieve carbon neutrality, Western Water carefully designed its water supply infrastructure to minimise its carbon footprint and has further reduced its carbon emissions through the use of energy generated from its biogas co-generation plant. Only a small amount of offsets, approved under the Australian Government's National Carbon Offset Standard (NCOS), were purchased to cover the remainder of the recycled water plant's emissions. Mr Brennan said the plant helped service one of the fastest growing regions in Victoria, which was also one of the driest parts of the state. "We're currently providing water, recycled water and sewerage services to about 150,000 residents, but our population is growing by about 6,000 every year," he said. "Looking ahead, we're expecting more than 50,000 residents to call Toolern home by 2030, and to meet their needs we're planning infrastructure now that will make them the first water-neutral development in Australia. "What that means is the amount of drinking water used in Toolern will be roughly equal to the amount of stormwater harvested for reuse. The amount of drinking water used by Toolern residents will be much lower than usual. They'll be using our Class A recycled water for their gardens and for flushing toilets." Mr Brennan said that Western Water saw the cogeneration plant as benefiting not only the environment, but also helping to improve the utility's bottom line by providing better value for customers. IWA World Water Congress & Exhibition 2012 The IWA will hold its biannual World Water Congress in Busan, Korea, from 16--21 September 2012. The IWA World Water Congress & Exhibition is a high-profile international event that attracts over 5000 water professionals, companies and institutions from across the globe. The event is a valuable and unique opportunity for the community of world-leading water professionals to meet, exchange ideas, explore the state of the art and debate the key issues underlying the science and practice of water. It is also where the entire water community congregates once every two years and where IWA specialist groups showcase their work and plan for future activities.

As of 1 July 2012 ACTEW, to be known as ACTEW Water, will assume direct responsibility for the management and operation of its water and sewerage network. ACTEW Water will bring together all aspects of Canberra's water and sewerage services including customer service, asset management of dams, pipes, pumps and treatment plants, and maintenance of all water and sewerage network infrastructure. ACTEW Water and ActewAGL will work together to continue to deliver high quality essential services to their customers. Other than water bills looking a little different, the introduction of ACTEW Water will have no impact on Canberra water and sewerage customers with all contact, billing information and customer support services remaining as they currently are.

Funding for the project includes a grant of A$66.5 million ($65.3 million USD) from the Commonwealth of Australia's Department of Resources, Energy and Tourism. The project will be developed through a special purpose company, Victorian Wave Partners (VWP), which is 100 per cent owned by Ocean Power Technologies Australasia (OPTA), which in turn is owned more than 88 per cent by OPT and 11.76 per cent by S&P/ASX50 energy company Woodside Petroleum. Manufacturing and development of the project is planned to commence in 2013 and deployment of the 28 PowerBuoys is expected to be completed in 2017. A significant number of jobs is expected to be created associated with fabrication, deployment and maintenance operations over the life of the power station. The 19MW project could provide energy to approximately 10,000 homes. For the project, Lockheed Martin will assist with the design of Ocean Power Technologies' PowerBuoy® technology, lead the production and system integration of the wave-energy converters and support overall program management. Lockheed Martin and OPT have been collaborating since 2004, first on the development of an Advanced Deployable System for the US Navy and most recently to design and launch utility-scale wave energy converters off the coast of Reedsport, Oregon. OPT's Australian-born founder and VWP Chairman Dr George W Taylor said: "According to the World Energy Council, wave energy has the potential to produce around 2,000 terawatt hours of electricity a year, or enough power to meet 10 per cent of the world's current energy needs. Australia has very attractive wave resources and this percentage could be significantly higher."
