The 2017 refurbishment required new penstock gates, trash screens, platforms, access ladders, isolation bulkhead gates and storage racks.
The latest works bring the critical infrastructure in-line with current workplace safety and water-use efficiency regulations.
The original Berembed offtake regulator and trash rack system was constructed in 1910. The Berembed Weir, located on the Murrumbidgee River, is managed by WaterNSW. AWMA was the Principal contractor responsible for site demolition and preparation requirements as the well as the design, manufacture and installation of new infrastructure. The Berembed Weir is heritage listed, requiring extreme caution during all stages of demolition and construction. Adhering to extensive environmental and OH&S requirements was also paramount.
Ten stainless steel TLF penstocks were supplied, each accommodating 9m of head pressure for the offtake regulator.
The penstocks were installed in embedded guides with integrated concrete blockout panels to replace the original steel multi-leaf gates.
Fixed stainless steel trash screens were installed on all ten bays and may be easily removed if required. An improved 20m long walkway replaces the original offtake access platform. Access ladders and a custom 6m high stairwell were also supplied.
Two mild steel bulkhead gates and storage racks allow isolation of the penstock gates when required.
