Delivering resilient water resources for all water users in the Lachlan catchment.

Transition to Water Infrastructure NSW

As of 1 July 2021, responsibility for the proposed Lake Rowlands to Carcoar Dam Pipeline project transitioned from WaterNSW to the Department of Planning, Industry and Environment’s Water Infrastructure NSW, which is a Division of the Water Group.

For project continuity, key project staff have also moved across and previous WaterNSW project specific contact points (email and phone numbers) are being forwarded. Water Infrastructure NSW has since been working closely with a range of partners to identify opportunities to deliver collective benefits to the Belubula Valley through this project.

About the project

Water Infrastructure NSW initially commenced preparation of a Final Business Case to explore the option of building a water transfer pipeline from the Central Tablelands Water-operated Lake Rowlands Dam to the larger Carcoar Dam. This follows recommendations by Infrastructure NSW in the 2018 State Infrastructure Strategy and the NSW Government's Lachlan Valley Water Security Study.

Since actively liaising with stakeholders and partners, a strategic decision has been made to develop a Final Business Case that will include the assessment of both the Lake Rowlands to Carcoar Dam pipeline project and the Lake Rowlands Dam Augmentation project, previously proposed by Central Tablelands Water.

The 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 projects, along with potential additional options to improve the efficiency and resilience of water management within the Belubula Valley.

To reflect this close alignment between both projects and the partnership between Water Infrastructure NSW and Central Tablelands Water, the project previously known as the Lake Rowlands to Carcoar pipeline project is now the Belubula Water Security Project.

The Final Business Case for the Belubula Water Security Project will be developed to align with the Lachlan Regional Water Strategy which is currently being finalised by the Department of Planning, Industry and Environment. The Lachlan Regional Water Strategy will identify policy, planning and infrastructure options that deliver resilient water resources for all water users in the Lachlan catchment.

The Final Business Case and the Lachlan Regional Water Strategy are supported through funding from the Snowy Hydro Legacy Fund. The Lachlan region draft strategy was released for public exhibition in 2020. More information on the Lachlan Regional Water Strategy.

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.


  • achieving the primary water security objectives in the Lachlan Valley
  • providing benefits to customers
  • easing the future impact on existing customers’ water prices
  • 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 in order 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 development of a Final Business Case for the Belubula Water Security Project as part of the Mid-year Economic and Fiscal Outlook.
