Marsden Park, NSW
Blacktown Waste Services
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. Ennovo 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.
Blacktown Waste Services required a landfill gas (LFG) flare for their Marsden Park Landfill in order to control potential off-site gas migration and to generate carbon credits. Biogas Systems were engaged for the supply and installation of a 1,000 m³/hr high temperature (HT) flare as well as the installation of a gas collection system (GCS) once final capping levels and layout was confirmed.
The disciplines covered included the following:
- NGERs assessment
- GCS design and installation
- Pumping trial
- Elevated flare monitoring and maintenance
- GCS monitoring and maintenance
- HT flare design and supply
- Ongoing flare and GCS monitoring, servicing, and maintenance
- Data management and ERF reporting
