Veolia Water Solutions & Technologies Australia has been awarded the contract to upgrade water treatment facilities at Australia's largest electricity generating company, Macquarie Generation. Macquarie Generation operates Liddell and Bayswater Power Stations in the Hunter Valley of NSW, approximately 250kms north of Sydney.
The contract, worth A$80M, will upgrade the water treatment facilities located at Bayswater Power Station to current technology, and increase capacity to improve water quality in Lake Liddell. This will ensure the reliability of Liddell and Bayswater Power Stations and enable them to continue producing 40% of NSW power for the long term, within the limits of available water.
High quality water is essential for the efficient and reliable operation of power stations. To prevent scaling in the cooling water systems, naturally occurring impurities must be removed before the water is used. This project will increase capacity for water conservation and improve efficiency of water use by removing the naturally occurring impurities from river water stored in Lake Liddell. The quality of water used at Liddell and Bayswater has been affected by reduced access to high flow water, and the capacity of the existing water treatment plant to treat the quantity of water required from Lake Liddell. Lake Liddell was originally constructed to provide cooling water and storage for Liddell Power Station in the early 1970s. Bayswater Power Station, Australia's largest power station, was constructed in the mid 1980s and also uses water from the Lake.
The A$80 M contract demonstrates Macquarie Generation and Veolia Water Solutions & Technologies shared commitment to responsible environmental management through innovative solutions that guarantee health & safety and protect the environment.
