developed to fasten the pipes from the composite to the collector pipe (Figure 3). Due to its limited thickness and its low hydraulic conductivity in contrast with the surrounding waste, the minitube blanket network won't obstruct the downward leachate flow into the waste mass and reduce the potential for plugging the perforated LFG collectors. Nevertheless, some specific measures will be taken to manage the condensates (gradation of the support with a slope away from the manifold, condensate drain at one end of the manifold, etc.). Waste is placed directly over the minitube blanket (Figure 4). A minimum of 3 feet (0.9 m) of selected waste should be placed on top of the geocomposite prior to operating a compactor over the area.
