Landfill Gas Pipe Selection and Installationby William M. Held, SCS Field Services, United States,
Eric R. Peterson, SCS Field Services, United States,
Abstract: Sanitary landfills present a unique array of pipe selection and installation criteria when designing landfill gas (LFG) control and recovery systems. Factors that must be considered include chemical corrosion resistance, temperature characteristics, ability to withstand differential settlement, and weatherability. In addition, the ease of pipe installation and repairs must be considered due to the safety precautions required when trenching and working in buried refuse, which is actively producing methane. Pipe materials historically used in LFG systems include polyethylene (PE), polyvinyl chloride (PVC) and fiberglass.
