Abergeldie to deliver the Diamond Bay Package under the Refresh Vaucluse and Diamond Bay project

Abergeldie has been awarded the Diamond Bay Package as part of Sydney Water’s Refresh Vaucluse Diamond Bay project, a major initiative to improve wastewater infrastructure on Sydney’s South Head peninsula.

The package includes the construction of a new (below-ground) wastewater pumping station at Eastern Reserve, Dover Heights, and new gravity and pressure pipelines connecting to the existing network in Vaucluse. Once complete, the works will support the transfer of wastewater to the Bondi Water Resource Recovery Facility for treatment.

Abergeldie's appointment follows the successful delivery of the Parsley Bay Package, which is nearing completion, and reflects the strong partnership between Abergeldie and Sydney Water in delivering complex water infrastructure. Throughout the delivery of the works at Parsley Bay, Abergeldie worked closely with residents, community groups, key stakeholders and local council to minimise impacts and maintain open communication, an approach that will continue throughout the delivery of the Diamond Bay Package.

CEO Mark Bruzzone said the team is proud to continue its role in the delivery of this critical infrastructure, which will provide lasting benefits for the community and environment.

“We are pleased to continue working with Sydney Water on this important project. Refreshing the wastewater system in Vaucluse and Diamond Bay will improve water quality in the harbour and along the coast and protect the health of the community and marine life. It is a powerful reminder that infrastructure is about far more than engineering—it is about creating a legacy for the communities we serve. For me, it perfectly captures what Building Better Communities means to Abergeldie."

Site establishment for the Diamond Bay Package commenced on 24 September 2026, with construction activities scheduled to begin after site establishment is complete.
