While manual drilling cannot be used everywhere in Senegal, in areas with favorable geology the cost of a hand drilled well is less than ¼ of the cost of a conventional machine drilled well under similar conditions. Manual drilling allows large capital investment in equipment to be replaced by locally made tools and labor. There is no difference in the final product between a machine drilled well and a manually drilled well, drilled to the same depth, equipped with the same casing and gravel pack, and developed using the same method.
