Landfill Design is conducted in AutoCAD using Digital Terrain Modeling and Civil Engineering Design Software. Grading Plans, Base Liner Plans and Closure Plans are modeled by computer and cross-sections are developed illustrating the design in various configurations. Design for New Lined Landfills include: Overall Site Planning, Grading Plans, Liner Systems, Leachate Collective System, Leachate treatment System, Storm water Management System, Landfill Gas Collection System, Landfill Gas Energy Recovery and Cogeneration, Landfill Capping and Closure System, Landscape and Vegetation Plan, Hydrogeology.
