AWMA water control gates automatically mitigate tidal and flood waters to protect MacLeod Morass from saline intrusion, near Bairnsdale Victoria.
Parks Victoria engaged Alluvium Consulting to develop a design solution for the saline intrusion that was increasingly impacting the valuable ecosystems within MacLeod Morass.
AWMA designed, manufactured and installed an appropriate gate and control arrangement to meet the requirements of the design. Two ULF undershot penstocks allowing for a clear waterway of 2.8m wide x 1.4m high were manufactured from marine grade aluminium and installed by AWMA at the site.
AWMA’s Technical Services division provided full gate automation and solar panels. The gates are programmed to allow water from the morass to flow out to the river, but prevent water from high tides back into the morass.
This fully automated site utilises a PLC to monitor outputs from level sensors located on both sides of the gates. Depending on the water level readings, the controller will either open or close the gates in accordance with the preprogrammed settings.
A Next G alarm system notifies Parks Victoria staff of fault alerts including low battery, flow blockage or irregular level sensor readings.
