The facility will ensure that residents across the city continue to receive safe, secure, and reliable drinking water, especially during periods of compromised water quality caused by storms, droughts, or bushfires.
ACCIONA, in a joint venture with SUEZ, has been selected by Sydney Water to construct the new Prospect Pre-Treatment Plant, a vital infrastructure project aimed at safeguarding Sydney’s water supply.
The facility will ensure that residents across the city continue to receive safe, secure, and reliable drinking water, especially during periods of compromised water quality caused by storms, droughts, or bushfires.
The Prospect Pre-Treatment Plant will serve as a critical upstream process to the Prospect Water Filtration Plant, which provides nearly 85% of Sydney’s drinking water. The new pre-treatment facility will have an initial capacity of 500 million liters per day (MLD) and will include key components such as intake screening, an advanced water clarification process, chemical storage and dosing facilities, a residual handling system to manage waste byproducts, as well as an administration building and comprehensive site services.
The contract value is AUS $322M (€199m).
LOCAL LEADERSHIP
ACCIONA was established in Australia in 2002 and has become one of the country’s leading infrastructure companies.
In 2009, the company was awarded one of its most emblematic projects in Australia, the Adelaide desalination plant. The plant has a capacity of 300,000 m³ per day and serves a population of two million. It was the first of its kind in the country, incorporating advanced pre-treatment to improve energy efficiency and increase the recovery of treated water for human consumption.
In 2011, ACCIONA was awarded its first water project in Western Australia, consisting of the design, build, operation and maintenance of the Mundaring Water Treatment Plant, which provides water into the Goldfields, one of the state´s nine regions.
In early 2024, ACCIONA was selected to design, build, operate and maintain the future Alkimos Seawater Desalination Plant (ASDP) in Perth for ten years. The design and construct project is scheduled to deliver drinking water in 2028, as part of an overall program of works valued at AU$2.8 billion (€1,724 million) to secure drinking water to millions of Western Australians
Beyond the water sector, ACCIONA is developing a number of large infrastructure projects in the country. Recently, it was selected by the Government of Victoria to build the first series of tunnels for the Suburban Rail Loop East project in Melbourne. The AU$3.6 billion (€2.2 billion) contract will transform Melbourne’s public transport network, mange the city’s growth and reduce the number of vehicles on the road.
In 2023, ACCIONA was also awarded the AU$1.4 billion (€850 million) contract to build the eastern section of the HumeLink electricity transmission line in New South Wales. The company is also building the Western Harbour Tunnel, valued at approximately AU$4.24 billion (€2.746 billion), the largest construction contract in ACCIONA’s history, which recently commenced tunnelling.
Other major contracts in the country include the construction of the runway at the new Western Sydney International Airport (Nancy Bird Walton); the central section of Sydney Metro West, the new underground railway that runs through much of the country’s largest city; and the removal of level crossings on the Frankston railway line in Melbourne.
