The Prospect Pre-Treatment Plant is using a bespoke sustainable concrete mix
Acciona has announced that the first pour on a major NSW water infrastructure project in Blacktown, using specifically designed sustainable concrete, has been completed.
The Prospect Pre-Treatment Plant project in Blacktown in Sydney’s west has reached a significant milestone with the pour, says Acciona.
“The structures team successfully delivered the base slab for the Densadeg unit [optimised flocculation settling tank with external sludge recirculation], establishing a critical foundation for the facility,” it says.
“This stage involved 570 cubic metres of concrete and 350 tonnes of steel reinforcement, reflecting the scale and precision required for the build.”

The concrete mix was specifically designed and tested to meet strict quality and sustainability standards. It includes 55 per cent supplementary cementitious materials and outdid the client’s specification, achieving a 23 per cent reduction in embodied carbon.
Acciona said this improvement demonstrates how innovative design can enhance environmental performance. The project is being delivered in partnership with French utility company SUEZ for Sydney Water.
Once the Prospect Pre-Treatment Plant is operational, it will provide an essential upstream process for the Prospect Water Filtration Plant, which supplies close to 85 per cent of Sydney’s drinking water.
