A major step has been taken to tackle rising groundwater and salinity issues in the Lower Burdekin, with Sunwater completing significant upgrades to a nearby irrigation channel.
The project, part of a $25 million regional initiative, aims to reduce groundwater levels that threaten local farms and the surrounding environment.
The latest phase of the project involved upgrading and lining a section of the open channel on Cadio Road, Upper Haughton, identified as a likely contributor to rising groundwater. These upgrades aim to reduce channel seepage and help manage the issue.
Sunwater successfully lined 2.6 km of open channel, using 38,480 square metres of impermeable
geomembrane, to prevent water migration from the channel and into the ground.
Additionally, six stormwater outlets and 11 existing concrete structures were modified to accommodate installation of the liner.
Sunwater CEO Glenn Stockton recognised the magnitude of the issue, and said the company is committed to nullifying the issue.
“Rising groundwater is a complex issue that impacts farmers across the scheme, the broader catchment and the environment, including the nearby Great Barrier Reef,” said Stockton.
“Enhancements to irrigation practices are also critical to reducing drainage impacts and lowering the groundwater levels across the region."
Other project work being undertaken by Sunwater includes installing bores with the intent to remove and redirect water from the aquifer and improving efficiencies of the Gladys Lagoon water distribution system.
“We continue to work with the Queensland Government, local grower groups, agronomists, and scientists to identify sustainable solutions for areas impacted by rising groundwater,” said Stockton.
