Stantec selected to design the proposed Cooranga Weir in Queensland’s Burnett Region

Supporting long-term water security and agricultural growth

02/25/2026 BRISBANE, AUSTRALIA TSX,NYSE:STN

Stantec has been engaged by Sunwater to deliver the detailed design for the proposed Cooranga Weir, an important water infrastructure project that aims to strengthen water security and support agricultural productivity in Queensland’s Burnett Region.

The proposed weir, located on the Boyne River downstream of Boondooma Dam, will provide up to 2,500 megalitres of new water storage. This additional capacity will help improve the reliability of existing water allocations and create opportunities for future agricultural expansion.

Under the contract, Stantec will prepare the full design for the nine‑metre‑high, 180‑metre‑wide structure, including engineering design, technical drawings and construction support. A team of 15 Queensland‑based specialists will deliver the work, demonstrating our ongoing commitment to local expertise and regional project delivery.

Natalie Muir, Regional Director, Water for Stantec Australia, said the project builds on Stantec’s long history of helping communities manage and strengthen their water systems.

“We’re proud to partner with Sunwater on the Cooranga Weir project. Improving water reliability is vital for irrigators and the wider Burnett Region,” Ms Muir said.

“Our team brings strong local knowledge and deep technical experience.  We’re focused on designing a solution that supports future agricultural productivity and delivers lasting value for the region.”
