• Announcing exciting new partnership

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    We are pleased to announce that we have partnered with Comdain Infrastructure and WSP on the Refresh Vaucluse and Diamond Bay project. Together, we’ll refresh the wastewater system in Vaucluse, Dover Heights and Diamond Bay to put an end to the continuous discharge of untreated wastewater into the ocean.

    By re-directing wastewater flows from these catchments to the nearby Bondi treatment plant, we’re protecting the health of the community and marine ecology by reducing the impact to the ocean by at least 93%.

    Detailed construction design has kicked off with community consultation as its cornerstone. During this stage, the delivery contractor will be looking to optimise the project's design with a view to further reducing impact to the community and environment.

    Construction of this exciting project is expected to commence next year.

    We’re stopping the continuous discharge of untreated wastewater into our ocean.

    From Watsons Bay to Dover Heights, the wastewater system is out-of-date. The wastewater we collect is not treated, instead it flows directly into the ocean at three points along the cliff -face. It’s time we fixed the system.

    Back in June we released our Review of Environmental Factors (REF), which looked at the environmental impacts of the work we need to do to divert the wastewater system to the treatment plant in Bondi.

    We asked for community feedback and we received 33 written submissions. These submissions and our responses to the issues raised have been compiled into a Decision Report, which is now available to download.

    However, in responding to these submissions, we did more than just write a report. We also got our technical team back in to do some more investigating. We wanted to make sure that we didn’t just listen to what you had to say but also, act on it.

    Parsley Bay

    Following the submissions, we had another look at the new pump station at Parsley Bay. We spoke to surrounding residents and to Woollahra Council and have come up with a new design.

    We have changed the layout of the pump station in Parsley Bay to minimise its impact on the surrounding vegetation and rocky terrain. This is in line with community and Council expectations.

    You can read more in Section 3 of the Decision Report.

  • World Ocean Day marks next milestone to clean Vaucluse and Diamond Bay’s blue backyard

    We're one step closer to changing history!

    Below the cliffs of Vaucluse and Diamond Bay, wastewater flows directly into the ocean untreated and this is no longer acceptable. 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.

    After years of planning, we’ve landed a solution that has the support of the local and wider Sydney community. Our solution will see wastewater diverted away from the ocean and sent to a nearby treatment plant in Bondi, maximising the use of Sydney Water’s existing network while keeping construction and environmental impacts to a minimum. We still need to build new infrastructure, but it’s just enough to get the job done.

    We’ve been assessing the potential construction and environmental impacts of building this solution. This work is now complete and we have a Review of Environmental Factors (REF) for you to look at.

    Head to the document library on the right to read our latest newsletter, providing an overview of the proposed solution and download the full REF.

  • Finalising the concept design

    Following topographical and geological investigations and working closely with the community, the solution design to divert the last three untreated wastewater coastal outfalls in Sydney is nearing completion.

    Given the limited open space, geology, as well as the highly sensitive heritage, coastal and harbour iconic locations, the main challenge was always to find suitable sites to locate two underground pumping stations.

    In determining those sites, we listened to our Community Reference Group (made up of local residents as well as representatives of Woollahra and Waverley Councils) to minimise possible construction and environmental impacts, while designing solutions that enhance our amenity at sites where work needs to be done.

    Almost all the new infrastructure will be located below ground. Anything above ground, such as valves or electrical kiosks, will be minimal and designed to blend as much as possible with the existing environment.

    New wastewater pipes, ranging between 20cm to 37.5cm in diameter, will be laid using trenchless technology up to 80m below ground, so there will be minimal construction impacts during or after construction. There will be some short sections of open trench work on the road verges where we connect to the existing network.

    Sydney Water will continue to work with the community, as well as local councils to refine design aspects. The final solution design will be displayed in March 2020, when we seek formal submissions from the public as part of the environmental approval process. Construction is expected to occur in the second half of 2020. Click here to view or print the concept design map.
  • 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.

  • Diamond Bay catchment design

    There are two existing ocean outfalls at Eastern Reserve and Diamond Bay. We plan to connect the two ocean outfalls, then pump the wastewater to the existing wastewater network at Old South Head Road.

    The existing pipe is large and has capacity to easily get the wastewater to the treatment plant at Bondi. Once at Bondi, the wastewater will be treated and discharged into the ocean through deep ocean outfall pipes.

    Diverting the Diamond Bay catchment involves:
    • Intercepting the existing outfalls at Eastern Reserve and Diamond Bay
    • Installing a 30cm wide pipe to connect Diamond Bay to Eastern Reserve
    • 33L/s pumping station at Eastern Reserve
    • 20cm wide rising main to connect to the existing Rose Bay sub main
    Working with Waverley Council and guided by local input, we will refine the design to blend with the environment. We will also contribute to Council’s planned improvements to the clifftop boardwalk at Diamond Bay. You can view or print artist impression of Eastern Avenue Reserve here.
  • Connection points at Rose Bay

    We need to connect the pipes in Vaucluse and Watson Bay to a new pipe, and pump the wastewater to the existing Rose Bay network.

    It will be achieved through the installation of a 37cm wide gravity main running from Carlisle Street and a 35cm wide pressure main running from Parsley Bay. These mains will connect to the existing Rose Bay submain in Dover Road.

    This will involve some short sections of open trench work on the verge of roads where we need to connect to the existing network. The work is expected about four to six weeks to complete.

    The works will not affect traffic as the construction will be occurring on the road shoulder. You can view or print the map showing these connections here.
