The development of Rookwood Weir, 66km south-west of Rockhampton, Queensland, will allow valuable water from the lower Fitzroy River to be captured and used across the region.
After an extensive tender evaluation process, the Acciona and McCosker Contracting joint venture selected AWMA to be the delivery partner for all custom water control gates associated with the fishlock element of the works.
Working with the construction team, Sunwater and GHD, AWMA shall soon finalise designs.
The water control gates required for this project consist of a number of hydraulically actuated stainless steel overshot and undershot penstocks and sidewinder gates, along with various manually deployed bulkheads and stopboards.
With a yield of 86,000 megalitres, Rookwood Weir will be the largest weir in Queensland when completed, and the largest built in Australia for the past 75 years. Construction has begun, with overall completion expected in late 2023.
