6 hybrid wells the difficulty of constructing large diameter wells which adequately penetrate the aquifer and which combine minimal resistance to inflow through the caisson with structural stability has led to some modifications. Between the early 1930’s and today, the dug well has evolved in some places from minimal, unlined holes to concrete lined structures with specified depth and yield, and with improved hand dug wells: choice of technology and construction manual, by stephen p abbott. A shallow well dug by hand held tools (eg hoe, shovel etc) it 30 why opt for shallow well technology in most cases, communities will go for shallow wells because of the following reasons 31 they can acquire a well using their own resources (low cost and locally available.
Traditionally, dug wells are formed and built by initial excavation of the land area through the use of a hand shovel until it reaches lower than the water table and when the incoming water surpasses the bailing rate of the digger after the digging, when the water has begun to seep out, the well. Normally, a hand dug shallow-well is about one to two meters (1 to 15yards) in diameter, depending on the size of tools used a hand-held hoe is the commonest tool used a small bucket, tied to a rope, is used to remove the dug soil from the hole 30 why opt for shallow well technology in most cases, communities will go for shallow wells.
