Downer to deliver $100m upgrade on Loganholme wastewater facility QLD
A range of upgrade works – with a combined value of approximately $100 million – is now underway at the Loganholme Wastewater Treatment Plant (WWTP) in Queensland and Downer has been appointed to undertake the works.
The upgrade will include the construction of a new permanent biosolids gasification facility, which is the first of its kind in Australia.
Relocation of underground services has already commenced ahead of the demolition of the existing biosolids (sewage sludge) dewatering building, which is where the permanent biosolids gasification facility is set to be built.
The construction of the $27 million permanent facility follows the successful trial conducted in 2020. The new facility will transform sewage sludge into renewable energy and biochar – a safe, environmentally friendly product – once it is up and running by mid-2022.
In March, construction will commence on a 1,000kW solar array that will help in power treatment operations as well as reduce the local council's carbon footprint. This $3.6 million project will include about 3,000 solar panels that will cover up to 3,700m2 .
Other works include a $6 million makeover of an old wastewater lift station (pump station), which involves replacing old pumps, valves and pipework to improve the management of incoming wastewater flows and enhance operator safety.
Later this year, upgrades to the WWTP's main treatment process are expected to get underway. This project is estimated to cost $69 million and it will involve the construction of a modern membrane bioreactor treatment facility.
Upgrading the membrane bioreactor technology will increase the plant's treatment capacity from 45 million litres a day to 67 million litres a day – equivalent to 100,000 more people – to accommodate the future growth in population.
“I was on-site recently at Loganholme and met several key team members who will be involved in the delivery of these projects over the next two years. It was pleasing to see that the team are ready to kick off with the solar array and biosolids gasification project shortly,” Downer's Water Services South General Manager Chris Yeats said.
The entire project will be providing employment opportunities for the local community as well as save up to $27 million in operational costs over two decades.
The approximately $100 million upgrade is being delivered by the Logan Water Partnership which is comprised of Downer, WSP Australia and Cardno.
Together with Logan Water, the partnership is set to deliver up to $1 billion worth of water and wastewater infrastructure over the next nine years across the City of Logan.

$100m funding to deliver 12 bridge strengthening works across TAS
While strengthening works are being carried out to nine Tasmanian bridges, tenders have been opened for 12 more bridges this year as part of a $100 million upgrade program.
The projects to upgrade Tasmania’s freight route are jointly funded by the Australian and Tasmanian Governments under the five-year Freight Capacity Upgrade Program – each committing $80 million and $20 million respectively.
“The Australian Government is committed to improving road safety and freight efficiency across Tasmania.
“We know how important it is to deliver infrastructure that will ease congested roads while also creating opportunities for Tasmanians.
“That is why we will continue to partner with the Tasmanian Government to deliver the Freight Capacity Upgrade Program,” Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King said.
By strengthening or replacing bridges and improving sections of roads, this program of works will help increase freight capacity of critical and regional freight routes across the State.
15 roads and bridge strengthening projects under the program have already been completed to date, including Pipers River Bridge as well as sections on the Bass, Midland, Lyell and Huon highways.
A $2.2 million contract has been awarded to Fulton Hogan to advance strengthening works on nine bridges.
“The program is supporting Tasmania’s economic growth by increasing freight efficiency, enabling increased safe operating loads, and making travel times more predictable for freight operators.
“It supports productivity by improving the roads freight vehicles travel on day to day.
“Repairing and strengthening these sections of road and bridges will also improve road safety for all road users and reduce maintenance costs,” TAS Infrastructure Minister Kerry Vincent said.
Six of the nine bridges are on the north west – at Argent River, Arthur River, Mole Creek, Leslie Station Creek, Don River and Pardoe Creek.
Meanwhile, the other bridges are at Wellards Creek, Norforlk Creek and Allans Creek on the Arthur Highway in the State’s south east.
Work at eight sites is now underway, with some nearing completion. Construction to strengthen the bridge at Leslie Station Creek, on the other hand, will begin this year.
As part of the Freight Capacity Upgrade Program, a total of 35 bridges are currently planned to be strengthened and three to be replaced.
“These much-needed bridge strengthening works will increase road and bridge network capability to increase freight productivity for critical state industries such as agriculture and manufacturing.
“The Australian Government will continue to invest in infrastructure projects across Tasmania to ensure efficient and safer travel for truck and heavy vehicle freight well into the future,” Senator for Tasmania Anne Urquhart said.
