 includes a series of gas extraction wells. The wells are typically formed by drilling a hole into the refuse pile and inserting a perforated pipe into the hole. The space around the pipe is typically backfilled with a porous material to facilitate gas flow. The wells are connected together by a series of collector pipes. The collector pipes are connected to a fan which provides the necessary vacuum to extract the LFG from the refuse pile. The LFG is then fed into a flare which burns the gas.
The temperature of the gas within the refuse pile can achieve temperatures as high as 90.degree. fahrenheit (F) to 140.degree. F. depending on the type and moisture content of organic matter in the refuse pile, as well as the other site specific conditions. The amount of gas produced also depends on these factors and on the age of the landfill. Generally, a landfill will produce its maximum amount of gas between three and seven years after it is closed. When the gas being drawn up through the wells reaches the collector piping on the surface, it is cooled by the ambient temperature of the air. As the gas cools, condensation forms on the inside of the piping. The piping is pitched to allow the condensate to flow to a collection point or dump. If the piping system has a plurality of collection points, the condensate is pumped by conventional means to a central collection or accumulating tank.
Until now, the condensate formed in the gas collection piping was released back into the landfill. Under-the new Subtitle D Regulations for municipal solid waste facilities, landfill gas condensate must be collected unless the landfill gas collection system is operated within a landfill equipped with both composite base liner and leachate collection systems. The current methods of disposal include discharging the condensate into an on-site leachate treatment system or transporting the condensate to an industrial wastewater treatment facility. Only a limited number of landfills can make practical use of the aforementioned solutions. Many landfills, due either to their design or location, cannot economically use these solutions. Smaller landfills located in rural areas are in great need of an economical solution. An alternative solution for these and other landfills is needed.

The collector pipe are connected to a fan which supply the necessary vacuum to extract the LFG from the refuse pile. The LFG is then feed into a flare which burns the gas.

The amount of gas produced also depends on these factors and on the age of the landfill. Generally, a landfill will produce its maximum sum of gas between three and seven years after it is close. When the natural gas being drawn up through the wells reach the collector piping on the surface, it is cooled by the ambient temperature of the air. As the accelerator cools, condensation forms on the inside of the piping. The piping is pitched to leave the condensate to flow to a collection point or dump. If the piping arrangement has a plurality of collection points, the condensate is pump by conventional means to a central solicitation or accumulating cooler.
