Diamond Bay

Below the cliffs of Vaucluse and Diamond Bay, wastewater flows directly into the ocean untreated.

It’s time for change and we’re continuing to work to ensure this iconic area of Sydney gets the clean, blue backyard it deserves. Under the Refresh Vaucluse Diamond Bay project we are building new infrastructure to divert the flows from the last three remaining ocean outfalls in Sydney to the Bondi Resource Recovery Facility (WRRF).

The project scope includes:

  • two new pump stations (one in Parsley Bay and one in Eastern Reserve)
  • 3km of new wastewater pipelines
  • upgrade existing infrastructure such us vent shafts and man holes

Whilst challenging, we know this is the right thing to do and we need you to get involved as we fix this problem once and for all.

Refreshing the wastewater system in Vaucluse and Diamond Bay offers multiple benefits—improving the harbour and coastal water quality, as well as protecting the health of the community and marine ecology.

The project is currently in detailed design with construction expected to start in 2024.
