ACCIONA To Deliver The Malabar System Investment Program

ACCIONA has partnered with SMEC to form the Malabar System Alliance (MSA), to work together with Sydney Water to deliver the Malabar System Investment Program.

The program improves and increases wastewater treatment capacity supporting population and service growth across Sydney’s south and west. The first scheme within the ten-year program involves upgrades to the Liverpool and Glenfield Water Resource Recovery Facilities to enhance the region’s wastewater network, improve system resilience, and ensure the sustainable management of resources into the future.

MSA’s innovative design maximises future opportunities for purified recycled water production and controlled river release, while optimising investment across the system. By harnessing and applying state of the art processes, the design is expected to deliver up to a 60 per cent improvement in energy efficiency and significantly improve long-term operational performance through the consolidation of treatment into a single secondary facility.

Bede Noonan, ACCIONA’s CEO Australia and New Zealand, said ACCIONA combines local expertise with global experience to deliver world-leading wastewater solutions.

“ACCIONA is proud to be collaborating with Sydney Water and our partner SMEC to deliver such a critical project for the people of Sydney. Having designed and constructed more than 335 wastewater treatment plants across 5 continents, we are looking forward to bringing this extensive capability to the successful delivery of this project.” said Mr Noonan. “

James Phillis, Chief Executive, Infrastructure + Energy at SJ Group (SMEC) shared, “At SMEC, we’re passionate about creating infrastructure that strengthens communities and safeguards the environment. Through our partnership with Sydney Water and ACCIONA, we’ll deliver wastewater solutions that ensure long-term sustainability and improved liveability for Sydney’s communities.”

MSA unites the expertise of ACCIONA and SMEC in delivering advanced wastewater treatment upgrades that enhance system capacity, performance, and environmental sustainability across Sydney. The MSA partners have, to date, worked together to successfully deliver more than $3B worth of projects across Australia.”

Construction is scheduled to commence following detailed design and procurement, with completion expected in 2029.
