Irrigation project saves water for Queensland growers


The $32.54 million Mareeba-Dimbulah Efficiency Improvement Project to enhance water delivery to over 17,000ha of far north Queensland farmland has been completed. 

The project, undertaken by Sunwater, was jointly funded by the federal government (contributing $11.6 million through the National Water Grid Fund) and the Queensland government (contributing $20.94 million). It has upgraded key water infrastructure so that more water will go to growers in the Atherton Tablelands. 

“This project will increase access to reliable water across the region and deliver a major boost to local growers, generating around $20 million per year in increased agricultural production,” deputy prime minister and minister for Infrastructure Transport and Regional Development, Barnaby Joyce said. 

“Securing water access is game-changing for our farmers and their communities, as it creates jobs, wealth and a stronger agricultural sector. That is why the Australian government is investing $3.5 billion in projects just like this under our 10-year rolling plan for vital water infrastructure across the country, providing a long-term strategy to build the dams, weirs and pipelines that our agricultural and regional communities need and deserve.” 

The Mareeba-Dimbulah Efficiency Improvement Project will save up to 8,306 megalitres of high-value water through new modernised infrastructure, which will reduce losses and improve service reliability to growers. 

“As Queensland’s minister for Water, I am thrilled to see this project finalised and even happier the construction component of these water-saving works provided jobs for 18 Queenslanders,” Queensland Water minister Glenn Butcher said. 

“Queensland’s vital agricultural sector stands to benefit, as growers will be able to better service a variety of crops, including sugar cane, bananas, mangoes, avocados, coffee, tea trees and vegetables. Thanks to this project, $20 million of which was funded by this Queensland government, water will now be delivered to the region based on demand, which we know will improve reliability and maximise the amount available to growers.” 

The project replaced and installed 14km of pipeline, installed 125 automated control gates in irrigation channels and upgraded 157 water offtakes. 

“I am pleased to see this vital project complete and ready to benefit locals,” senator for Queensland and special envoy for Northern Australia, Susan McDonald said. 

“This forms part of the Australian government’s unwavering commitment to secure Australia’s water future – including in North and Far North Queensland. We have already committed nearly $500 million to water infrastructure projects in north and far north Queensland that will not only increase water security in established agricultural areas, but also unlock agricultural opportunities in new regions, backing our economy, exports and job creation.” 

The broader efficiency project highlights Sunwater’s ability to carry out complex modernisation projects that have tangible outcomes for customers. 

The new automated channel gates measure and regulate water flow, which will subsequently improve the supply scheme’s ability to meet grower demand, as well as make more water available. 

With construction now complete, the process to validate water savings is underway. Once the savings are confirmed, new water allocations will be made available for sale.
