LOGAN City Council will rollout almost $1 billion of water and sewage infrastructure over the next nine years in partnership with the private sector after awarding its largest contract in history.
Downer Utilities and consultants WSP Australia and Cardno Queensland won the tender and will form part of the Logan Water Infrastructure Program Alliance.
Logan City Council has been in alliance partnerships for the past 10 years.
The council's road and water infrastructure acting director Daryl Ross said the contract was valid for five years with options for an additional two extensions of two years each.
"Quality tenders were received from tier one contractors and engineering consultants," he said.
"These high-calibre companies see Logan as a progressive council and they were keen to commit to long-term partnerships."
The current Logan Water Infrastructure Alliance has been planning, designing and rolling out Logan's water infrastructure with a focus on growth areas.
Projects include the Cedar Grove Sewage Treatment Plant which will operate next year and service the Greater Flagstone region.
Another sewage treatment plant has been approved at Chambers Flat, along Pleasant View Road, but construction will not start until after 2021.
Key projects include water and wastewater pipelines and pump stations, water reservoirs and wastewater network management technologies.
A Logan City Council spokesperson said the new partnership would benefit the local economy, environment and community.
This would be achieved through more high value infrastructure, local employment and training opportunities and installation of technology to limit environmental and social impacts.
