ABSTRACT
Governments in Africa face a twin challenge in terms of water supply and sanitation. Firstly to close the gap in rural areas where only two in five people have access to water supply and fewer than one in five have access to sanitation; and the urban population explosion at a rate unique in history, which is characterized by growing slums, unemployment, poor access to water, sanitation and health services. In both these environments, groundwater resources have a major role to play and their sustainable utilization has become of strategic importance.
