Operations, Maintenance, and Monitoring

Tetra Tech provides operations, maintenance (O&M), and monitoring services for gas collection and leachate collection systems at active and closed landfills and landfill gas-to-energy (LFGTE) facilities throughout the United States.

Tetra Tech’s highly skilled field service staff maximize solid waste facility efficiency by keeping systems properly tuned and by managing routine and emergency repairs for landfill gas collection and control systems (LFGCCS) and leachate management systems. Our staff are skilled at knowing how to tune wells, and under which circumstances a well should be opened or closed. Our differentiators include understanding landfills’ complex systems and wide-ranging parameters and applying that information to positively affect our clients’ bottom line. With a focus on ensuring overall landfill waste management, our work includes routine maintenance and major overhauls of landfill gas collection and control systems, leachate and condensate collection and pumping systems, and groundwater monitoring networks.

From monitoring landfill surface gas emissions to operating landfill gas control systems, our clients rely on us to ensure efficient, safe, and productive operations and to maintain compliance with regulatory requirements. Tetra Tech is also skilled at training our clients’ personnel to conduct routine monitoring and operations of LFG collection and control systems.
