The most suitable after-uses of landfill sites include parks, pasture land, parking lots, recreational activities and other facilities not requiring much excavation. Boreholes and sampling points should be installed down gradient to monitor the impact of leachate on the underlying groundwater. When the final elevations are reached, a low permeability capping layer is placed. A clay liner is usually placed at the base of the excavated surface. Once a suitable site has been located, the engineering construction of the facility can begin. Prior to the design and construction of a landfill site, geological, geophysical and geotechnical characteristics of the site must be investigated to ensure the best location, stability of the facility and to minimize its effects both in the short and long terms. Due to the health hazards involved in the above mentioned methods of disposal, landfills which are carefully engineered depressions in the ground into which wastes are put until rendered innocuous through physical, chemical and biological degradation, remains the most useful tool in municipal solid waste management. The main objective of this paper is to highlight the requirements of involving the appropriate professionals in the construction and management of wastes disposal facilities. Recycling and re-use is a waste reduction strategy because some wastes cannot be recycled. Incineration as means of waste disposal provides a partial solution, but also poses a serious hazard of air pollution. Open dumping is inexpensive, but poses a serious health hazard, damage due to air pollution, groundwater and runoff pollution. Ocean dumping puts wastes out of the sight of the people but contributes to the pollution of the oceans to which the world turns increasingly for food. Wastes can be disposed off in various ways such as landfilling, ocean dumping, open dumping or can be reduced in volume by recycling, incinerating and compacting. Wastes are unwanted materials which are unfit for use and they could be generated from industrial, extractive, municipal or agricultural activities.
