Nyngan to Cobar pipeline project

Proposed pipeline to upgrade existing infrastructure and provide long-term water security and reliability to the region.

The man-made Newey Reserve in Cobar, NSW.

About the project

Water Infrastructure NSW has developed a Final Business Case for a proposed pipeline and pump stations between Nyngan and Cobar.

The project aims to upgrade the existing pipeline and pumping infrastructure to provide long-term water supply reliability for the region.

The business case involves a range of technical, environmental, cultural heritage and economic studies as well as comprehensive engagement with stakeholders and community members. The business case will be considered by government over the coming months to inform an investment decision.

Why the project is needed?

The existing Nyngan to Cobar pipeline and pumping stations are the main source of water supply to the township of Cobar and its surrounding industries and mines. The existing pipeline and pumping stations are nearing the end of their design life, with the emergency backup system also at risk of failure. This presents a risk to water reliability for the township and mines in the area.

This project seeks to replace the pipeline and pump stations through a business case to NSW Government, and funding applications to both the NSW and Australian Governments.

Project benefits

The proposed pipeline project will:

  • improve water reliability for Cobar and surrounding townships
  • increase water accessibility and reliability for industries including agriculture and mining
  • improve the use of technology including pipeline monitoring.

Project location

The Nyngan to Cobar Pipeline is located in far-Western NSW, with Cobar being the endpoint. Cobar is situated 300 km from Dubbo and 450 km from Broken Hill and has a population of approximately 4,000 people.

Project timelines

Water Infrastructure NSW has prepared the business case for the pipeline and pump stations. The draft business case has been reviewed through the NSW Infrastructure Investor Assurance Gateway 2 review process and will be considered by government over the coming months to inform an investment decision.

It has been identified the replacement of the current pump stations at Nyngan, Hermidale and Cobar is urgent and unavoidable and should be fast-tracked while the business case is being considered by governments. As a result, the project is now staged so the pump stations can progress to address the immediate critical needs:

  • Stage 1 – replacement of pump stations at three locations
  • Stage 2 – replacement of pipeline

NSW has committed to funding 50 per cent of the costs to replace the pump stations and are awaiting confirmation from the new Australian Government concerning previous commitments to provide the remaining 50 per cent. This additional funding will allow Water Infrastructure NSW to progress the replacement of the pump stations, while continuing the relevant studies and investigations required to inform the draft business case to replace the Nyngan to Cobar pipeline.

The project team is concurrently undertaking the relevant technical, environmental and cultural heritage investigations to progress the business case for the pipeline.

Water Infrastructure NSW is leading the development and delivery of the Nyngan to Cobar Pipeline Final Business Case. The Cobar Water Board is a key stakeholder of the project but is not responsible for developing the business case.

What guidelines need to be followed when developing the final business case? 

NSW Treasury sets the guidelines, key assumptions and parameters around the development of NSW Government business cases.
