The $27 million Swan Hill Modernisation Project (SHMP) required infrastructure upgrades and new fishways for the Lower Murray Weir and Fish Point Weir as part of Goulburn- Murray Water’s (G-MW) Connections Project.
The Swan Hill Modernisation Project in north-west Victoria required the lowering of the Little Murray Weir pool by 2 metres, as well as integrating a fishway, automated control system and debris screens.
AWMA custom manufactured dual leaf undershot ULF Penstocks for the fishway entry and exit points. A fully integrated stopboard frame and walkway design provided savings on installation costs.
The second site, Fish Point Weir required a new automated overshot gate to be retro-fitted to the existing structure, as well as three ULF undershot penstocks and a set of modular stopboards for a fishway management.
A custom designed 2-in-1 MultiBay LayFlat Gate provides automated overshot flow regulation with integrated bulkhead gates for emergency isolation. The structure measures 6100mm wide x 4300m high, allowing 5400mm clear water for a 2200mm supply level. Associated equipment includes real-time level sensors, access platforms, lifting devices, storage systems and actuation systems encased above flood levels.
AWMA’s gate automation control and monitoring platform allows the same gate control methodology to be applied to both Lower Murray Weir and Fish Point Weir, reducing the whole-of life costs for both sites.
