Water Hand Pump/nUntil recent centuries, all artificial wells were pumpless dug wells which were excavated with diameters large enough to accommodate men with shovels digging down to below the water table. Such wells were at times lined with stones or bricks; extending this lining into a wall around the well to reduce both contamination and injuries by falling into the well. Modern dug wells are hand pumped./nWhile the cost of drilling is directly proportional to the depth where water can be pumped from, the average cost of installing a hand pump, along with maintenance of the hand pump for 5 years is approximately $200./nFor more info. please visit: http://www.hidaya.org/environment/cle…
