Oxley Creek Sewerage Treatment Plant at Rocklea is Brisbane’s second largest sewage treatment plant, treating an average of 65 million litres per day of domestic sewage and trade waste from the southern and western regions of Brisbane.

The plant became operational in 1969 and since then several new process units have been added to meet current and future demand. The plant has a thermal hydrolysis plant, which David Solley (2000) investigated during his Churchill Fellowship.  This converts biosolids from five sewage treatment plants to produce green electricity and fertiliser. The plant treats up to 95,000 tonnes of waste sludge per year and was the first thermal hydrolysis plant in the southern hemisphere.

David Solley (2002) is a process engineer with over 30 years’ experience in water and wastewater treatment. He was awarded a Churchill Fellowship in 2000 to investigate the upgrading of large wastewater treatment plants for nutrient removal, and currently works for consulting engineers GHD.  He has lead successful process and multi-disciplinary teams for many significant wastewater and reuse treatment projects, including the last upgrade of Oxley Creek STP. The projects have covered nutrient removal for municipal and high strength wastewater, biosolids treatment, and water recycling processes.
