Lake Rowlands Dam to Carcoar Dam pipeline

Lake Rowlands Dam to Carcoar Dam pipeline

About the project

WaterNSW has been engaged by the Department of Planning Industry and Environment (DPIE) to prepare 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 WaterNSW-operated Carcoar Dam.  This follows recommendations by Infrastructure NSW in the 2018 State Infrastructure Strategy and WaterNSW’s Lachlan Valley Water Security Study.

The Final Business Case for the Lake Rowlands to Carcoar Dam pipeline will be developed to align with the Lachlan Regional Water Strategy which is currently being finalised by DPIE. 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 is scheduled to be released for public exhibition in mid-2020. For more information on the Lachlan Regional Water strategy go to

The proposed two-way pipeline will help contribute towards improving water access reliability for the region and industries by transferring water from Lake Rowlands Dam to Carcoar Dam when appropriate volumes are available.  This will result in efficient, long-term storage of available water and increase operational flexibility for urban and rural water supply.

The development of the Final Business Case will involve stakeholder consultation, as well as comprehensive environmental and engineering studies.  These studies began in the third quarter of 2019 and will be finalised in early 2021. Outcomes of this study will be included in the Final Business Case and submitted to Infrastructure NSW as part of the IIAF gateway process.
