Noosa Water Treatment Plant
Veolia Water upgraded the Noosa Water Treatment Plant to significantly improve water quality by adding an advanced treatment stage of ozone dosing and biological activated carbon (BAC) filtration.
The plant capacity was also increased by 20 per cent to 45 million litres per day by upgrading and optimising the existing plant structures and processes, dramatically improving the conventional treatment process.
The project was delivered under a design, build and operate (DBO) contract with a 15 year operations period. It was the first water treatment plant in Australia to be delivered under this model. The upgrade, completed in 1999, was carried out while Veolia Water operated the existing works to maintain stringent water quality requirements.
The plant was Australia's first major ozone biologically activated carbon water treatment plant and it continues to produce water of a significantly higher standard than the requirements of the Australian Drinking Water Guidelines. The plant has also added fluoride to its water to bring it in line with Queensland regulations.
In late 2011, the plant will become connected to the South East Queensland Water Grid, which also includes the Gold Coast Desalination Plant and the Western Corridor Recycled Water Project.
