An apparatus and method to internally provide apertures inside polyvinyl chloride (PVC), high density polyethylene (HDPE), or any polymeric pie, plastic pipe-riser (blank casing) in existing landfill gas recovery wells (extraction wells) that have been installed at Municipal Solid Waste Facilities are described. By creating additional apertures in landfill gas recovery well risers, landfill gas derived from the decomposition of waste is allowed to enter the existing riser and extraction/recovery system. This process saves time and cost associated with drilling additional wells to capture landfill gas from subsequent layers of the waste body. The process assists in maintaining regulatory compliance by capturing landfill gas and preventing it from being emitted into the atmosphere.
