E – 1444 Operation and Maintenance of Landfill Gas Systems
Intended Audience: civil engineers, geotechnical engineers
PDH UNITS: 3
This course discusses the need for an operation and maintenance (O&M) plan for a landfill gas collection system that addresses the following: extraction wells; LFG monitoring probes; condensate collection and treatment; and flare station. A site-specific monitoring program should be established that is flexible and performance based. LFG needs to be monitored on a regular basis to enable adjustments to be made to the wells to maximize extraction, prevent migration, and minimize drawing oxygen into the landfill. The procedures need to be regularly evaluated as changing climatic and operational conditions can have an effect on the results obtained.
