Burlington County Landfill, Burlington, NJ: Installation of extraction wells in 36-inch diameter boreholes up to 115 feet deep for methane gas extraction.
Landfill Gas and Leachate Systems
In order for landfills to be compliant with State and Federal regulations, methane and other gases produced as a result of decomposition of organic waste, must be captured and managed efficiently. Moretrench offers a range of landfill-related design, installation and maintenance services for both passive and active gas collection and condensate and leachate collection.
