The tender process for the scheme closed in November 2017 and work will start soon after the federal and Tasmanian governments committed $25.27 million and $20 million, respectively, in addition to $12.03 million raised via water sales to farmers.

Scottsdale Irrigation Scheme is the fifth and final Tranche 2 scheme to be delivered.

It is understood that Deputy Prime Minister and federal Infrastructure Minister Michael McCormack will announce the funding in Northern Tasmania on Wednesday.

Tasmanian Primary Industries and Water Minister Sarah Courtney said the scheme would provide 8600 megalitres of water to more than 80 farmers.

“Today’s announcement by the Australian and Tasmanian governments that work will begin immediately on the $57.3 million Scottsdale Irrigation Scheme will turbo-charge agricultural production in North-East Tasmania,’’ Ms Courtney said.

“North-East Tasmania is one of our most productive agricultural regions and the Scottsdale scheme will add security of supply for more than 80 farmers and incentivise further investment and jobs in regional Tasmania.

“Farmers are genuine partners in these nation-leading irrigation schemes by investing with government in the capital works and additional on-farm infrastructure like dams, pipes and centre-pivots or drippers,” she said.

Tasmanian Liberal senator Richard Colbeck said water from the Scottsdale scheme would supply more than 100 North-East properties.

“This project is a significant economic boost for Tasmania’s North-East, not just in terms of water supply but also with $57.3 million worth of construction,’’ Senator Colbeck said.

“Tasmania is one of the only places in Australia where we are actively developing water resources.”
