Development WA undertook development of a historical landfill site located in Bibra Lake, Western Australia. The landfill site was remediated to allow construction and use of commercial buildings in a precinct arrangement. DBD Environmental were engaged to provide a specialist landfill gas (LFG) risk assessment and design a gas mitigation system to protect the surrounding buildings and ensure compliance.

The site has a number of unique aspects that presented both technical and financial challenges. Through the use of continuous monitoring equipment, a robust LFG risk assessment was achieved which in turn informed the design basis of the gas mitigation system.

The main disciplines undertaken included the following:   

  • Continuous and spot gas monitoring
  • Surface gas emission assessment
  • Services investigation and field investigations
  • Drilling works and monitoring well installation
  • Development of a Conceptual Site Model (CSM)
  • Landfill Gas (LFG) Risk Assessment
  • Odour modelling
  • Design of a LFG mitigation system
