I Am Confused, Why Are There Round Dug Wells in Africa, and Now Driven Wells?
My guess: redundancy Drilled and driven wells require pumps, but with a dug well you can always fall back to the traditional bucket and rope method if the pump fails/there's no power/etc.
Good point ,,,Pardon the pun. A dug well needs no power. As i think about it, that low tech round well does seem like a very costly project. Where I can drive a point with one other helper we can do it in a day. As is common in Maine. It does require power and a pump. The round well seems that it would be a several day maybe weeks to complete maybe needing more than 2 folks to do. Yet it is a low maintenance project that requires no power and pumps. How long would you say this well will last? Indefinite? Probably a good investment. Maybe one of those NGO's ,,, ya think?
