Vaucluse catchment design
The existing wastewater pipes for Vaucluse and Watsons Bay converge and connect to the Vaucluse ocean outfall in Parsley Bay. We therefore need to work in Parsley Bay to redirect the catchment to new pipes.
The new infrastructure required for this includes a wastewater pump station. We worked with the Community Reference Group and Woollahra Council and looked at the suitability of several possible sites for the new pumping station. Most were ruled out because of heritage sensitivities or community impacts. We agreed to locate the pumping station underground where the existing amenities building is located at the rear of the Parsley Bay Reserve car park. Before starting, we will build toilet block amenity closer to the recreational area to ensure there are no disruptions for community members wishing to use the facility.
Diverting the Vaucluse catchment involves:
- Intercepting the network connection to the existing ocean outfall pipe at Parsley Bay
- Constructing a new pumping station in Parsley Bay (70L/s)
- Installing 35cm wide pipe using trenchless horizontal directional drill that will connect existing main at Rose Bay
We will continue working with Woollahra Council to develop the design of the new amenity building. View or print the artist impression here.
