SMEC
has
partnered

to
form
the
Malabar
System
Alliance
(MSA)
January 21, 2026
SMEC has partnered with ACCIONA 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.
