Guinea worm control: Assessing the effectiveness of drum-lined water holes

Summary The purpose of the paper is to examine the feasibility of used oil drums as a lining material for shallow rural wells. The discussion focuses upon the comparison of the water quality in the oil drum-lined holes with other local water sources. The response to the innovation, from a range of guinea worm prone rural environments in Ibarapa district, Oyo State, Nigeria, was encouraging. The study noted substantial reductions in cyclop population (potential for guinea worm infection) and improved water quality in the sanitary wells as compared to rural ponds. Investigations also reveal substantial saving in costs in using oil drum-lining as opposed to concrete. Findings point to the need for this kind of water scheme as opposed to sophisticated boreholes, and deep well programmes, especially in situations of limited funds and technical skills necessary to install and maintain water supply systems.Dr Abimbola Y.
