One of the city’s wastewater treatment plants will receive a $100 million upgrade, and another decommissioned in a major infrastructure overhaul.
Logan City Council will shut down the Beenleigh plant and throw millions of dollars into upgrades at the current Loganholme facility.
The first stage of work began at Loganholme last week.
City of Logan’s largest water treatment facility services around 300,000 residents and is home to Australia’s first permanent biosolids gasification facility.
The $27 million facility transforms sewage sludge into renewable energy and a safe, environmentally friendly product called biochar.
Trials were conducted last year and the new recycling project is expected to be operational by mid-2022.
Once running, it will reduce the volume of biosolids (sewage sludge) by 90%, saving the environment and ratepayers’ hip pockets.
It’s not the only way ratepayers are expected to save.
About $69 million will be spent on upgrades to the Loganholme main treatment process.
That means a modern “membrane bioreactor treatment facility” will be built, covering 3500 sqm.
City infrastructure chair Cr Teresa Lane said the technology will increase the plant’s treatment capacity from 45 million litres per day to 67 million litres per day and will service an additional 100,000 people.
This technology would work hand-in-hand with the current conventional treatment process and Loganholme, and enable the transfer of flows from the Beenleigh plant, which will be de-commissioned.
The move is estimated to save ratepayers around $27 million in operating costs over the next 20 years, Cr Lane said.
The city’s drive to carbon neutrality will also take another leap forward with the construction of a 1000kw solar array at the plant with construction starting next month.
The $3.6 million project will include around 3000 solar panels covering around 3700 sqm.
Meanwhile, a 30-year-old wastewater pump station at the plant will get a $6 million makeover including new pumps, valves and pipework to more efficiently manage incoming wastewater flows and enhance safety for operators.
Cr Lane said the upgrades would minimise community impacts associated with conventional treatment processes and maximise the use of the flood-free land available on-site at Loganholme.
“This is a world-class facility and the envy of councils Australia-wide,” Cr Lane said.
“While the infrastructure upgrades will streamline operations and create efficiency, they’re creating employment and work opportunities for hundreds of construction jobs for Logan residents and contractors.”
