Sewage from the majority of Flagstone and Jimboomba will be transferred to a new wastewater treatment plant at Cedar Grove as part of a strategy to guide long term planning for essential wastewater infrastructure in Logan’s priority development areas.
The strategy was today endorsed by Logan City Council.
Roads and Water Infrastructure Committee Chairman, Councillor Phil Pidgeon, said the infrastructure would be rolled out over the next 25-plus years, with more than $500 million required to deliver it to the community.
"These developments are bringing thousands of new residents to our city in the next three decades, so it's important that we get the infrastructure done right from the start," he said.
"While Economic Development Queensland, a State Government entity, has approved the two developments, they have worked with us and the major developers involved to get the strategy to this stage, even recognising our desire for the strategy to look at the broader catchment so we provide infrastructure in the most cost-effective way.
"The strategy encompasses not only Yarrabilba and Flagstone, but also Logan Village, Park Ridge and part of Chambers Flat to ensure we get it right environmentally and economically."
Land for the new wastewater treatment plant at Cedar Grove was acquired in 2011.
A second new treatment plant will also be built to service Yarrabilba, Logan Village, Greenbank, North Maclean, Park Ridge and part of Chambers Flat.
"The second treatment plant will bring significant cost benefits to Council, but we are yet to confirm where this will be located until we do further planning," Cr Pidgeon said.
"Temporary treatment plants will be located at Central Flagstone, Flinders, Greenbank and Riverbend before the Cedar Grove treatment plant comes online in 2019."
Cr Pidgeon said Council still needed to establish a funding model with EDQ before it would begin delivering the proposed trunk infrastructure through the Logan Water Infrastructure Alliance.
Environmental approvals are also required from the Department of Environment and Heritage.
"Developers will still be responsible for providing infrastructure within the developments, but we will provide the major infrastructure that leads to the treatment plants," he said.
"We will now start doing detailed planning to guide design and construction of the infrastructure and will update the community as we make progress through the various stages."
