Australia’s first biosolids gasification facility

Logan Water has pioneered an Australian first biosolids gasification facility. The facility transforms sewage sludge (biosolids) into renewable energy and a sustainable product called biochar. Biochar can be used by the agricultural, composting, building and other industries.

The Loganholme Wastewater Treatment Plant (WWTP) operated a trial biosolids gasification facility during 2020. A permanent facility is under construction and will be completed in early to mid 2022.

Research into the performance of the trial facility showed that Logan Water’s solution:

• is heat-energy neutral
• reduces the amount of biosolids for disposal by around 90 percent
• eliminates about 95 percent of persistent organic pollutants (POPs) like polyfluoroalkyl substances (PFAS), and
• reduces about 63 percenet of micro and nano-plastics in biosolids.

The process does not harm the environment and the resulting biochar contains bio-available nitrogen, phosphorus and potassium. Biochar also increases the water holding capacity of soil. This helps plants to germinate and grow in the hot Australian climate. 

Logan Water is progressing with the second stage of tenders from potential buyers of commercial quantities of biochar. The outcome of the tender process is expected in early to mid 2022.

Cedar Grove Environmental Centre

This award-winning centre is open daily from 5:30am to 6:30pm. Please note that the gates to the centre and carpark close at 6:30pm, please make sure you leave the Centre before this time.

Community members can visit the site to enjoy:

• a 2.5 kilometer walking track along the Logan River
• shaded seating and picnic tables
• parking, accessible toilets and drinking fountain
• viewing the Cedar Grove Landcare nursery and training facility.

Access is from Cedar Grove Road, and there is a public carpark at the end of the access road. Dogs on a leash are allowed but there is no access for motorbikes, horses, fishing or camping.

Apart from community facilities, the centre is home to Queensland’s first wastewater treatment plant to benefit the environment by producing record low nutrient levels in effluent and offsetting remaining nutrients through catchment restoration. Visits to the treatment plant by arrangement only. The site master plan was developed with a Community Reference Group. Minutes of the meetings of this group are available from Logan Water on request.

Chambers Flat wastewater treatment plant

A new wastewater treatment facility is needed to service development in the Park Ridge, Logan Village and Yarrabilba areas in the coming years.

The planned facility currently known as the Chambers Flat wastewater treatment plant (WWTP) will ultimately be constructed on part of a 144 hectare site at Pleasant View Road, Chambers Flat.

Current status

Logan Water continues to progress planning for a future wastewater treatment plant (WWTP) at the Chambers Flat site. Construction of the WWTP is not expected to commence until after 2032.

Community Reference Group

Council has established the Chambers Flat Community Reference Group (currently on hold).

The purpose of the Community Reference Group is to:

• enhance communication between Council and community members affected by the project
• increase our understanding of community feedback about the development of the Chambers Flat WWTP and connecting trunk infrastructure
• maximise opportunities for the community and environment as part of the project.

Loganholme Wastewater Treatment Plant upgrade

More than $100 million in major upgrade works are underway or recently completed at Loganholme Wastewater Treatment Plant (WWTP).

The upgrade will increase the plant’s capacity to process wastewater from our growing community, improve its environmental performance, and reduce operating costs for Council and customers.

On site, Logan Water is constructing Australia’s first permanent biosolids gasification facility. The facility will transform biosolids, sludge from wastewater, into renewable energy and a safe, environmentally friendly product called biochar.

A 1000 kilowatt solar array is now operating to help power treatment operations and reduce Council’s carbon footprint. The array includes around 3,000 solar panels.

The plant’s main treatment process is receiving a major overhaul. This includes construction of a modern membrane bioreactor treatment facility covering 3.500 square metres. 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. It will complement the existing conventional treatment process at the WWTP and enable the transfer of flows from the Beenleigh WWTP, which will ultimately be decommissioned.

The existing pump station at the WWTP has been upgraded with new pumps, valves and pipework to manage incoming wastewater flows more efficiently and enhance safety for operators.

Travis Road trunk water main project

The project involves construction of approximately 7.2km of trunk water pipeline and associated infrastructure.  The pipeline will be installed using a combination of open trench and underground drilling construction methods.

Where is it happening?

Construction of the new pipeline will occur between Travis Road water reservoir in Logan Village and the Seqwater water pump station in Chambers Flat via Bobermien Road, Stockleigh Road (section complete), Yore Road, Carabeen Road, Geoff Philp Drive and under the Logan River. The works will occur on Council-owned land and infrastructure easements.

When is it happening?

Construction is underway on the horizontal drilling component of the project. Open trench works between Lady Ardeen Drive and Yore Road will commence in late-January 2025 with an expected completion in approximately four months (weather and construction conditions permitting). Travis Road works will commence from February 2025.

What can I expect?

Logan Water will make every effort to minimise disruption to the community during these works. However, some localised construction impacts may be experienced at times including:

• Increased levels of noise, dust and vibration. The site team will implement measures to reduce these impacts as much as practical.
• Temporary driveway access restrictions at times. Logan Water will liaise with affected residents in advance of works.
• Changed traffic conditions including temporary road / lane closure(s), reduced speed limits and footpath closures.
• Frequent truck movements to and from work sites to allow machinery / materials to be delivered and removed.
• Some vegetation removal including trimming of overhanging branches. Logan Water will undertake all vegetation removal in accordance with Council and State Government requirements.
