Austral Wastewater Servicing

Sydney Water

Sydney, New South Wales, Australia

Diona was awarded the Austral wastewater infrastructure project as part of the South West Growth Centre (SWGC) to service development within the area.

Comprising 17,000ha, the SWGC is located within Liverpool, Camden and Campbelltown local government areas. There are 17 precincts within and is expected to include an estimated 110,000 new homes.

Diona’s technical expertise, as well as our ability to manage multiple contractors carrying various types of work on site was instrumental to the successful delivery of this project.

Our team was responsible for:

  • Wastewater pumping station – 77.6 L/s at 65.7 m head, 105-kW pump motor 3.6m dia x 11.2m deep wet well
