Who we are
Our HistorySydney Desalination Plant was constructed in response to the worst drought in 100 years, which saw Sydney's dam levels fall to 34%.
Sydney Desalination Plant History
The project was funded by the NSW Government and was originally owned by Sydney Water Corporation (SWC). Construction of the desalination plant took 3 years from 2007-2010. A purpose built wind farm was constructed by Infigen to provide 100% renewable energy for the plant. The first desalinated drinking water was delivered to Sydney in February 2010. The plant then ran continuously for 2 years, from 2010 to 2012, to prove plant capacity and reliability.
The NSW Government sold a 50 year lease on the plant in June 2012 backed by a 50 year water supply contract with SWC. The bid was won by a consortium of Utilities Trust of Australia (UTA), The Infrastructure Fund (TIF)Hastings Funds Management and Ontario Teachers’ Pension Plan at a cost of $2 .3 billion which includes the plant and the pipeline connecting the plant to the water supply network.
As a monopoly supplier of desalinated water to Sydney, the Sydney Desalination Plant is regulated by the Independent Pricing and Regulatory Tribunal (IPART). The plant is licensed under the NSW Water Industry Competition Act.
Dam levels rose to 98% in June 2012 and under the rules of the NSW Metropolitan Water Plan the plant came offline and into water security mode (standby mode). Sydney Desalination Plant Pty Limited has a 20 year contract with an operator, Veolia Water. Veolia operate and maintenance the plant and pipeline. Australia operate the plant under a 20 year contract and have up to 8 months to restart the plant once the instruction to restart is given. According to our operating rules, as set out by the government, the plant will be instructed to restart when Sydney's total metropolitan dam levels fallfor below 60% and we have up to 8 months to reach full capacity.

June 2012 - Sydney metropolitan combined dam levels Sydney dam levels rose to 98% and under the rules of the NSW Metropolitan Water Plan the plant came offline and entered water security mode (standby mode)
July 2012 - Regulated by IPART as a monopoly supplier of desalinated water
December 2015 - Tornado hit the Kurnell area causing damage to the plant. A reinstatement plan was agreed with government to repair the plant and have it ready to respond to a drought trigger by December 2018.
October 2018 – Plant tornado reinstatement complete. Plant ready to respond to drought trigger when it occurs
27 January 2019 – Sydney metropolitan combined dam levels fell below 60%, thus the plant is in restart.
