Abstracts: ABSTRACT Good design of a landfill site will prevent, or reduce as far as possible, negative effects on the environment, as well as the risks to human health arising from the landfilling of waste. It is essential that the designer adopt methods, standards and operational systems based on best current practice which reflect progress in management techniques and containment standards. The design process should be consistent with the need to protect the environment and human health. Landfill design is an interactive process incorporating the conceptual design proposals, the findings of the environmental assessment and environmental monitoring results, risk assessment and the conclusions reached in investigations. The fundamental objective behind waste management is that of sustainability. It is implicit therefore that landfill development and operation (which are intrinsically linked) should reflect this approach. This report outlines the design objectives and considerations that need to be taken into account in the design of a landfill. Management systems for the control of leachate, gas, surface water and groundwater are discussed. The design of engineering works associated with lining andcapping systems is considered.
