Oakey Abattoir is one of Australia’s largest beef processing plants. Its anaerobic lagoon and associated biogas cleaning and recovery facility extracts green energy biogas from wastewater streams to replace millions of dollars worth of natural gas previously consumed by the abattoir. Designed by Global Water Engineering and installed by CST Wastewater Solutions, the plant reduces dependence on expensive supplies of natural gas, reduces the facility’s carbon footprint and produces cleaner waste water.

CNF was engaged by CST Wastewater Solutions to:

• Undertake a design review to ensure the European design complied with the relevant Australian Standards, particularly those dealing with hazardous areas resulting from explosive gas atmospheres.
• Provide on-going engineering support for:
  • the equipment purchase;
  • compliance checking;
  • installation and commissioning of the gas processing facility;
  • flare, gas storage and boiler gas supply.

For the civil contractor, CNF was engaged to design the above ground lagoons that collected the wastewater and contained the biomass.
