50% Design Decision Report now available

Between February and May 2022 we consulted with stakeholder and the community on the 50% proposed design of the infrastructure.

We asked for community feedback and we received 216 submissions. These submissions and our responses to the issues raised have been compiled into a Decision Report, which is now available to download.

In response to your feedback we have made some changes to the proposal.

Parsley Bay
Following the submissions, we had another look at the new pump station at Parsley Bay. We have included safeguards, such as a gate at the proposed stairs and are looking at how we can further improve the aesthetics of the pump station.

We also changed the layout of the pump station and moved it further into the car park to minimise its impact on the surrounding vegetation and rocky terrain. This is in line with community and Council expectations.

We are progressing the design towards construction, which we expect to start mid 2023.

Rose Bay
We have reviewed the construction methodology for Carlisle St, Rose Bay. To minimise impacts to the community, mainly around traffic and parking, we will be changing the methodology from open trenching to trenchless along Carlisle Street, Rose Bay.

Eastern Reserve and Diamond Bay
We acknowledge the proposed design requires further refinement to minimise its footprint and visual impact. Engagement with residents and councils has led to the decision to re- visiting the infrastructure layout, location and design to divert the Diamond Bay outfalls

An independent geo-technical service provider has been appointed to carry out additional investigations and modelling of the area to complete independent verification of the geo-technical assessments of the construction site.
We are also pursuing alternative options for servicing the Diamond Bay precinct.

As we are revisiting the infrastructure layout and design to divert the outfalls, the construction timeline for this part of the project is yet to be determined.
