About the project

The Belubula Water Security Project aims to improve water availability, efficiency and security across the Belubula Valley through infrastructure.

Water Infrastructure NSW is pursuing a final business case investigating a range of options. These options are aimed at supporting sustainable water management in the Belubula Valley, considering risks to water security and reliability. This includes exploring the proposed water transfer pipeline from the Lake Rowlands Dam to the larger Carcoar Dam, following recommendations by Infrastructure NSW in the 2018 State Infrastructure Strategy and the NSW Government's Lachlan Valley Water Security Study.

Since initial engagement with stakeholders and partners, the decision was made to develop a final business case incorporating both the assessment of the Lake Rowlands to Carcoar Dam pipeline project and the Lake Rowlands Dam Augmentation project, previously proposed by Central Tablelands Water.

The final business case will be subject to a detailed options analysis consistent with the Infrastructure NSW Infrastructure Investor Assurance Framework (IIAF). This analysis will review both options, along with potential additional options to improve the efficiency and resilience of water management within the Belubula Valley. It will also align relevant regional water strategies.

The development of the final business case will involve broad community and stakeholder consultation, as well as comprehensive environmental and engineering studies. Outcomes of this study will be included in the final business case and submitted to Infrastructure NSW as part of the IIAF gateway process.

Benefits of the project would include:

  • achieving the primary water security objectives in the Lachlan Valley
  • providing benefits to customers
  • providing a greater level of water security.


Water Infrastructure NSW applied for additional funding from the Australian Government’s National Water Grid Authority (NWGA) for the Belubula Water Security Project to progress the amalgamated business case and review of water management for the Belubula Valley. On 4 February 2022, the Australian Government announced additional funding to support the development of the final business case.
