At present, there is a general lack of potable water in rural parts of Ethiopia. There are a number of ways of supplying such water: engine-driven pumps, from boreholes, shallow wells, springs, rivers, lakes, etc. Of the many alternatives, springs are widely regarded as the cheapest source of clean water. Hand-dug wells are another source of potable water. At present, however, most hand-dug wells are improperly constructed and use primitive water-lifting devices such as buckets and inner tubes that are unhealthy and time consuming. The use of hand pumps would facilitate the withdrawal of water from these wells. This report is essentially a comparison of some hand pumps that are in use in Ethiopia, both imported and locally designed and manufactured
