WELLS AND BORE WELLS ARE MAINTAINED AS AN ALTERNATIVE FOR THE DOMESTIC OR MINOR IRRIGATION HOWEVER CAREFUL STUDY OF THE SITE AND SOIL SHOULD BE MADE WHEN SELECTING A SITE.

People are facing hardship of water during the hot days and making arrangements for their personal use of water through various methods of construction of wells for domestic use of drinking water as well as the minor irrigation, with respect to the Government facilitation and subsidies from the various departments, however following no demarcation by way of careful study of the site and soil, when selecting a site for a well and a bore hole defined with a shaft of any diameter from 100 mm or more where in drilled well is usually referred to as bore well. As for the hill area selection of site for this duty is concerned, any pollution on the upstream side is concerned may affect the water, weather in side this area or not ;pollution below the well but outside this area would not sensibly affect the water . Open wells generally get their supplies from the first water bearing stratum met after digging at which water stands at spring water level, while in the case of tube wells water can be drawn from the stratum lower down in addition to the top strata large quantities of water can be drawn from a tube-well as compared to an open well. Tube wells are wells of small diameter and consist of tubes or pipes bored into the group water supplies of one or more water bearings strata. Tibe wells are worked mechanically, while open wells are worked by human or animal labour. In the case of shallow wells the water table of the shallow ground water which they tape is likely to fluctuate considerably thereby making the yield uncertain. Seasonal variations of water level may be very considerable in some localities. Drawing water out of shallow wells will lower the water table and might affect the adjoining structure, but deep wells give large and uniform yield. The group water level is a site which is heavily drawn by a series of wells as far a large town supply, usually falls a few metres permanently shortly after the pumping is regularly established. This permanent drop of ground water level must be taken into account in fixing the level of pumping engines and suction pipes.
