North Head Wastewater Treatment Plant

We're in the final planning stages of our Biosolids project to improve odour management and waste processing at the plant.

Work is expected to begin in mid 2019.

Our work will help improve our environmental footprint.

About the project

The purpose of this project is to construct two new digesters at the plant to better recycle the wastewater we treat. This will:

  • result in a better quality by-product (biosolids) that is 100% reusable
  • improve our environmental footprint
  • reduce odour emissions from trucks that transport biosolids to farms in regional NSW. 


The project will enable us to continue to cater for Sydney's growing future and meet the requirements of our Environment Protection Licence.
