Recycled water for Melbourne’s south east
Climate change, population growth and ageing assets present potential longer-term water security problems for Melbourne. Climate-independent water supply sources can help address the problem.
Melbourne’s Eastern Treatment Plant in Carrum produces over 130 billion litres of recycled water each year. However about 95% (123 billion litres) is treated and safely discharged into Bass Strait. Building a recycled water pipeline a short distance to the Dingley area would allow this valuable recycled water to be used to safely irrigate high-value horticulture crops, parks, sporting fields and green open space – rather than using potable water for these purposes.
A unique opportunity exists to lay a recycled water pipeline, or ‘purple pipe’, to enable a strategic and cost-effective way to provide recycled water to businesses and open space in and around the suburbs of Keysborough, Dingley, Heatherton, Clayton South, Sandringham and Cheltenham.
It has the potential to provide 800ML/annum of Class A recycled water to more than 40 priority sites including public parkland, some of Australia’s premier golf courses, commercial nurseries, market gardeners and industry.
This project is Action 6 in the Dandenong Integrated Water Management Forum’s Strategic Directions Statement.
