Water pumps are becoming more of a necessity for developing countries so that they might have a large enough water supply for the entire village. Water pumps are used to pump different amounts of water for drinking, washing, or irrigation purposes. The water used in the pumps comes from a variety of different sources such as rivers, underground aquifers etc. In countries that are developed water pumps are mostly driven by electric motors. Two popular pumps used in less developed countries are the treadle pump and the ram pump. The treadle pump is foot-operated, while the ram pump uses the power given off by the water flowing down in order to lift a small amount of water to a greater height. Water pumps are a great way for a country to increase its water supply although it does take some manual labor.
Take a look at how a windmill attached to a water pump in Papua New Guinea supplies an entire village. http://www.globalinnovationcommons.org/discover/challenge/papua-new-guinea-water-project
