Wilcannia Weir replacement

Transition to Water Infrastructure NSW

As of 1 July 2021, responsibility for the development and delivery of the Wilcannia Weir 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 (i.e. email and phone numbers) are being forwarded.

About the project

Water Infrastructure NSW is designing and constructing a new weir for Wilcannia on behalf of the State and Australian Governments under the Sustainable Rural Water Use and Infrastructure program. $30 million in funding has been announcement to replace the weir at a new site location that was supported and agreed upon by the community during previous investigations and consultation by the Department of Planning, Industry and Environment’s Water division.

The Wilcannia Weir was constructed in 1942 for the purpose of providing a more reliable town water supply for Wilcannia. Water levels have decreased due to development activities since the weir was built, causing the river to be altered and removed from the community of Wilcannia.

The new weir will provide long-term town water supplies to preserve and enhance the social, economic and environmental benefits for Wilcannia, its people and its surrounds.

A dedicated Water Infrastructure NSW project team has been assembled to undertake the concept design and environmental assessment for the new weir so the project can progress to the construction phase by the end of 2021, subject to receiving environmental approvals.


The new weir aims to deliver a range of benefits including:

  • improved water security for Wilcannia
  • enhanced cultural connection to the river
  • improved water management of the weir pool
  • increased tourism opportunities and investment
  • better recreational amenity to walk, swim, picnic and fish
  • improved native fish migration.

Community consultation

Water Infrastructure NSW understands the importance of the river to the community and want to design and construct a weir that meets community needs and expectations and maintains the strong connection people have to the river.

Community drop-in sessions, to share information and get feedback on the development of the project, are being held at key milestones. Regular updates to the community via newsletter, fact sheets, newspaper and radio are being made available.

Community engagement


Project schedule

The project is ongoing and Water Infrastructure NSW is preparing an Environmental Impact Statement which involves in depth environmental and cultural heritage assessments and community consultation.

Water Infrastructure NSW is committed to continued engagement with the Wilcannia community. The project team will communicate via phone, email, video meetings, advertisements, local radio and news. Project updates and flyers are providing information and we will continue to work closely with the community and stakeholders.
