The Adelaide Desalination Plant is now fully operational after a successful commissioning phase which has resulted in the supply of more than 14GL of drinking water to South Australian residents and businesses, according to the two consortia behind its design/construction and operation/maintenance.
AdelaideAqua Pty Ltd - a joint venture between TRILITY and ACCIONA Agua – now operates and maintains the Adelaide Desalination Plant under a 20 year contract with the South Australian Government owned water utility, SA Water. The joint venture took on management responsibilities for the plant on 12 December 2012 as part of a handover from the consortium which has designed, built and commissioned the $1.824 billion infrastructure project The project was completed and handed over for operations 19 days ahead of the original approved milestone of end of December 2012.
This consortium - comprising McConnell Dowell, Abigroup and ACCIONA Aqua - completed construction on the 100GL plant in December last year and the two consortia have worked together through the commissioning phase, drawing on their combined global expertise in the operation of desalination plants.
AdelaideAqua Pty Ltd has the paramount objective of delivering a safe and reliable supply of drinking water to South Australians while ensuring the Adelaide Desalination Plant operates efficiently, safely and sustainably.
“South Australia is the driest State on the driest continent on earth,” said TRILITY Managing Director Francois Gouws. “The Adelaide Desalination Plant ensures South Australians are protected from the environmental and economic impact of protracted drought.”
“The Plant has the capacity to provide up to 100GL of drinking water each year,” said ACCIONA Australia Managing Director Simon Hatcher, also a Director on the AdelaideAqua Pty Ltd Board. “This is equivalent of up to half of Adelaide’s current water needs.”
SA Water Chief Executive John Ringham confirmed the Adelaide Desalination Plant had delivered 32GL to South Australians since it commenced the commissioning phase in October 2011.
“Adelaide has experienced lower than expected water inflows into its reservoirs over the past six months and this has underscored the need for a desalination plant which will ensure the State’s population has a robust water supply,” Mr Ringham said.
The Adelaide Desalination Plant commenced construction in 2009 as part of the Government of South Australia’s Water For Good plan to secure water supplies for all South Australians and reduce the State’s reliance on the River Murray.
The Adelaide Desalination Plant is a state-of-the-art reverse osmosis plant which produces up to 300ML per day of drinking water from seawater. The project incorporates:
• An underground tunnel sources seawater approximately 1.5 kilometres from the Port Stanvac shoreline.
• A pre-treatment process uses disk filtration and ultrafiltration membranes to provide a high level of efficiency and reduce operating and maintenance costs.
• An advanced reverse osmosis membrane system extracts pure water at a high recovery rate.
• Highly efficient energy recovery devices and turbines recover spent energy from the reverse osmosis system and significantly reduce the plant’s energy demand.
• A remineralisation and disinfection system ensures the water produced meets drinking water standards.
• A highly developed diffusion system ensures discharge requirements under the EPA licence are met.
The Adelaide Desalination Plant has been supplying drinking water to South Australians since October 2011. It has received numerous State awards including the Australian Water Association Infrastructure Innovation Award in 2012.
