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. A comprehensive business case supporting funding applications for the replacement will be presented to both the NSW and Australian Governments.
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.
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 final 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
Funding for Stage 1 of the project totalling $45.5M has been secured with equal contributions from the Australian and NSW Governments of $22.75M. This 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 final 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 which is on track for the second half of 2023.
Water Infrastructure NSW is committed to building and maintaining respectful, trusted and collaborative relationships with our communities and stakeholders to ensure water infrastructure projects achieve the best possible outcomes.
We will be offering many opportunities for our communities and stakeholders, including First Nations communities, to engage with us and provide feedback as we develop the business case for the project.

Who is responsible for the delivery of the proposed project?
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 and will contribute to 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.
Additionally, Infrastructure NSW has guidelines around the investor assurance framework which the business case must comply with. As part of this, Water Infrastructure NSW is required to demonstrate any potential project is fit-for-purpose, economically viable and that potential impacts are managed.
