North Head Wastewater Treatment Plant

  • Location - Manly
  • Timeframe - work to begin in the next six months

Since 2017, we've been working to improve the odour management system at the plant. The next stage will focus on improving the way we treat wastewater and biosolids recycling. This will improve our environmental footprint, as well as reduce odour emissions from trucks transporting the biosolids to farms in regional NSW.

Most of the stormwater pipes and channels in the Sydney metropolitan area are the responsibility of local councils. Sydney Water owns some of the large stormwater pipes, channels and drains.

We work closely with local councils and other agencies to manage Sydney’s stormwater flows.
