Abstract
A landfill (10) having a leachate collection apparatus including a layer of geonet material (40) disposed above a liner (38) as its primary leachate flow path. Leachate flows along the geonet material to a collection trench (16) located along an edge (14) of a generally planar landfill area (12). The superior hydraulic conductivity of the geonet material (34) disposed above a liner (32) is provided below the primary drainage layer for additional ground water protection. A collection box 918) having both a leachate collection compartment (54) and a leakage collection compartment (56) is disposed in alignment with openings (80, 82) formed in the respective liner layers. The sealing surfaces (64,68) between the collection box and liners are all located on upper surfaces of the collection box.
