Malabar Wastewater Treatment Plant

We’re improving the reliability of the treatment plant to ensure we continue to meet our regulatory requirements. 

Work started in 2014 and is expected to be completed in early 2019.

Work at Malabar Wastewater Treatment Plant

We're working at Malabar Wastewater Treatment Plant to:

  • improve the reliability of the processes that treat wastewater
  • reduce operating costs
  • improve the quality of the Biosolids we produce
  • improve safety and working conditions
  • ensure we continue to comply with our environment protection licence requirements into the future.


Infrastructure and facilities

Our work to improve existing infrastructure above and below ground at the plant includes replacing or upgrading the:

  • screenings collection, transfer and handling processes
  • grit capture, dewatering and out loading processes
  • raw wastewater pumps
  • sludge and scum collection systems
  • sludge digestion and Biosolids handling and transfer systems
  • overall control system and other electrical equipment
  • water delivery infrastructure, compressed air, recycled water and underground ventilation systems.


We'll also remove equipment that's no longer required and landscape the site.

This work is being delivered by 4Malabar, an alliance between Sydney Water, John Holland, UGL Engineering and GHD.
