Large scale solar-powered wastewater treatment
Melbourne Water's Eastern Treatment Plant is home to one of the largest behind-the-meter solar farms in Australia, hosting 39,000 solar panels which are helping reduce the emissions that come from powering the sewage treatment processes.
Using food waste to power treatment plants
Greater Western Water is harnessing the power of organic waste at the Melton waste-to-energy facility.
The facility can treat up to 5,000 kilolitres of liquid food waste each year from local businesses and convert it into biogas.
Biogas generated from the waste-to-energy facility combined with an on-site solar array provides up to 100% of the Melton plant’s energy needs during the day.
Floating solar panels
Wannon Water will soon host Australia’s largest floating solar array which will generate more than 600 MW hours of renewable electricity per year, not only reducing greenhouse gas emissions but saving a significant amount of money in pumping costs.
More than 1,200 floating solar panels are being installed at Wannon Water’s Brierly Basin and are designed for efficiency by harvesting light from both sides.
