Abstract
A waste collection site having a fluid distribution structure, and the structure and related method, the structure including a geocomposite for placement on and between levels of collected waste and at least one pipe extending up from the geocomposite and adapted to receive the fluid from horizontally extending feeder headers. The permeable material includes a spacing layer between top and bottom layers, and a discharge manifold at the bottom of the pipe discharges the fluid between the top and bottom layers. The bottom layer has a flow rate F of fluid therethrough and the top layer has a flow rate F , where F <F , and the spacing layer maintains a space between the top and layers to permit flow of fluid therein to distribute the fluid. A geotextile usable as a layer of the geocomposite may be formed by modifying a non-woven needle punched geotextile, including the steps of calendaring the non-woven needle punched geotextile, and needle punching the non-woven needle punched geotextile after the calendaring step to create openings greater than 0.3 mm.
