Why are some bore wells fully cased while others hardly use any casing pipe?Borewell Drilling solutions.

In alluvial area, the entire depth of a bore hole needs to be cased to prevent it from collapsing. In order to allow water to enter into the well from the aquifers, small openings usually in the shape of thin slots are provided at appropriate locations in the casing pipe. The casing is assembled by joining blank and slotted pipes in desired lengths and sequences in such a way that on insertion, the slotted pipes face the aquifers to be tapped and the blank portions stay against non-productive formations. The bottom end of the casing pipe is also closed using a “bottom plug” to prevent entry of sand into the well during pumping of water from the well. Since, the entire well in loose alluvial formations is provided with a casing pipe, such wells are referred commonly as a tube well.

The annular space between the casing pipe and the bore is usually filled up with pea sized gravel of uniform size till the top of the first aquifer. Gravel filling is not extended up to the ground level so as to prevent entry of polluted water in to the formation from surface run-off through the gravel filled annular space. The remaining depth above the gravel pack is usually filled up with impervious clay. borewellmart Has licensed borewell drillers with high technical knowledge gained over their experience from various regions of india.
