This chapter briefly discusses landfill design, construction, and operation. It presents siting considerations, regulations, and other important steps before the design stage. In recent years, the landfill design philosophy has shifted from the dry-storage concept to the bioreactor approach. In the bioreactor approach, the moisture content of the municipal solid waste (MSW) is increased by recirculating leachate to enhance biodegradation. Landfill design involves designing physical elements of the landfill and operational systems. The major design components of a landfill are sub-base, liner, leachate management system, gas management system, final cap, and stormwater management. Monitoring is an important task during landfill construction/operation and after closure. Leachate, possible leakage through the liner system, groundwater quality, landfill gas migration, and stability are among the most commonly monitored aspects.
