Macquarie River Re-regulating storage

Macquarie River Re-regulating storage

About the project

WaterNSW has been engaged by the Department of Planning Industry and Environment to prepare a Detailed Business Case to explore the option of constructing a re-regulating weir on the Macquarie River. This follows recommendations by Infrastructure NSW in the 2014 State Infrastructure Strategy (PDF) and WaterNSW’s 20 Year Infrastructure Options Study.

The weir would be located downstream of Burrendong Dam, and between the townships of Warren and Narromine. The preferred location of the weir will be determined as the project progresses. It may be located near the existing weir at Gin Gin or at a location further upstream towards Rocky Point.

The development of the Detailed Business Case will involve stakeholder consultation, as well as comprehensive environmental and engineering studies. These studies began in early 2019 and will continue to mid 2020.  Outcomes of these studies will be included in the Detailed Business Case and be submitted to Infrastructure NSW as part of the Infrastructure Investor Assurance Framework gateway process.

WaterNSW has engaged GHD, an environmental and engineering consultancy, as a delivery partner for the project.

The project will be developed to align with the Macquarie Regional Water Strategy which is currently under development. The Macquarie Regional Water Strategy will identify policy, planning and infrastructure options that deliver resilient water resources for all water users in the Macquarie Valley.

This project and the Macquarie Regional Water Strategy are both supported through funding from the Snowy Hydro Legacy Fund.

Benefits

  • Achieving long-term water security strategic objectives in the Macquarie Valley
  • Improved delivery efficiency to customers downstream of Gin Gin
  • Reduced transmission losses when transferring and delivering water through the river system on an annual basis; and
  • Maximise available water for general security customers within the sustainable diversion limits set under the Murray-Darling Basin Plan.

Project Schedule

  • March 2019 – Project planning and investigations commenced
  • July 2019 – Consultation with stakeholders and potentially affected landholders commenced and will be ongoing
  • September 2019 – Field studies and detailed investigations  commenced
  • December 2019 - Concept design completed
  • Mid 2020 – Environmental Impact Statement (EIS) exhibition and Detailed Business Case submitted
