SA Water’s plans for a new nine megalitre drinking-water storage tank at Coomandook will bolster storage capacity along the Tailem Bend to Keith pipeline.
The 132km long Tailem Bend to Keith pipeline is the primary source of potable water for more than 10,000 people in towns along the Dukes Highway between Murray Bridge and Bordertown,
SA Water will be investing $10 million to construct the tank at Coomandook in order to improve water security for its customers in the Lower Murray, Mallee and Upper South East regions
The tank construction is part of SA Water's $89 million investment to refurbish 111 water storage sites across the state between 2016 and 2020.
SA Water general manager of communications and engagement Anna Jackson said the new infrastructure will sit alongside an existing tank at Coomandook to increase the pipeline's storage capacity by 30 per cent.
"Increasing the system's storage capacity can help diversify feed options within a supply network, and provide additional time to manage and resolve issues like pump faults or power failures before they turn into supply interruptions for our customers," she said.
The work involves constructing a new concrete reinforced post tensioned 5.8 metre high, 47m diameter concrete tank, which will be covered with an aluminium roof to maintain the safety of the treated water within the network.
South Australian company Leed Engineering and Construction will be responsible for undertaking the work, which is expected to be completed by mid 2019.
Ms Jackson said such water storages are essential in order to provide the region with world class water services.
“Investing in our water storages will ensure we can meet current and forecast demand, and continue to provide our customers with world class water services, well into the future,” Ms Jackson said.
"Ongoing water security will also support continued population and economic growth across the South East region."
The Tailem Bend to Keith pipeline and existing Coomandook tank were both built in the 1960s and feed 800km of branch mains that cover an area of more than 6470 square kilometres, including Coonalpyn, Meningie, Culburra and Keith.
