The following video shows a picture of a bore hole water supply to a village in Africa. This is the sort of thing we are trying to achieve in Mali with our Mali Program. A bore hole can supply several hundred to several thousand people. It can cost between £500 and £5000 depending upon the location and serve around 5000 people in the villages around. Bore holes can only be built in certain places, usually where the water table is not to deep and the supply of the water is clean. When building a bore hole you can often either pay a local firm a small amount to drill once and if there is no water you get nothing or you can pay an increased amount so that they keep drilling until you hit water.
