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 2023.

    Sydney Water owns the residence and depot currently located at 33 and 33A Lancaster Road, Dover Heights. We will demolish these and turn the site into a work compound with office space and onsite parking for staff.

    The demolition of the depot will commence on 25 July 2022 and will take about 2 weeks to complete. All work will happen inside the fenced in area of 33A Lancaster Road.

    Asbestos Removal

    Investigations by a licenced asbestos assessor have determined traces of non-friable asbestos in the building. This kind of asbestos is considered low risk as it is mixed with cement, so very hard and solid. A SafeWork NSW certified asbestos removal specialists will remove the asbestos inside the building before we start demolition of the building.

    An exclusion zone will be set up around the building, to prevent unauthorised access. The building is within the fenced in SW property, which is not accessible to the public. Signage will be in place to inform about the work including contact details. Asbestos air monitoring will be used during the works.


    Work Hours

    Our work hours will be from 7am to 3.30pm, Monday to Friday.

    We will not work on weekends or public holidays.


    We know our work can be disruptive, so we’ll make every effort to reduce any impact this work may have on you.

    Since the publication of the Decision Report last year, we have been focusing on Parsley Bay, predominantly the new amenities block.

    The feedback we have received so far shows just how important Parsley Bay is to the local community and we’re working hard to ensure that we minimise the impact our work will have on the surrounding community and the long term amenity of the reserve.

    The latest newsletter, which can be found here, will provide you with an update on where we’re up to and next steps.

  • 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.

  • Decision Report now available

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

    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.
