Sydney Water has started the final stage of a project to stop untreated wastewater entering the sea at three coastal outlets in eastern Sydney. The New South Wales government said on November 10 that the project would divert flows from Vaucluse, Diamond Bay and Parsley Bay to the Bondi treatment plant.

A pipeline to divert flows from Vaucluse is nearing completion. The final stage includes a new underground pumping station in Dover Heights and connecting pipelines to take flows from the other two outlets into the Bondi network.

The state expects the work to finish by mid-2028. Once the diversions are in place, the wastewater will be treated at Bondi before discharge through its offshore outlet.
