DH McMahon Groundwater Impact Assessment: Tumblong NSW Proposed Landfill
A 1 metre high engineered bund will be constructed on the northern and western boundary of the landfill, utilising compacted clay fill, these bunds, side slopes and floor will be subsequently covered with geosynthetic clay liner (GCL), high density polyethylene (HDPE) geomembrane and protection geotextile. A sump area for leachate collection and extraction will be constructed within Cell 1 and Cell 2. A series of slotted HDPE pipes laid within a minimum 300mm aggregate leachate drainage blanket will also be installed on the base of the landfill to collect and direct leachate into the two separate sump areas. Leachate will be pumped from the two landfill sumps via 400mm ID HDPE side riser where it will be carried via surface laid pipework to the clay, GCL and HDPE lined leachate storage dam. The leachate storage dam has been designed to meet the requirements of the NSW EPA Environmental Guidelines: Solid Waste Landfills (2016).
