I have a small land at Neral, Maharashtra which is a hilly area. Once monsoon & winter gets over, we get severe water problem. Tried to find borewell options in couple of times. But at both the times, identifier gave two different locations. So don’t know where to drill. So before going drilling , I wanted to be assured . hence I am desperately looking for some genuine person or company who can identify underground water storage at my place. There is a river flowing 3 kms away from my place. Couple of land owners in my area tried for borewell , but they didn’t get water.
Can you pls help me in knowing the name & contact number of Genuine water dedecters . Thanks!
Lot of people think there is a huge source of water below ground, even I had same assumption untill few years back. It is a myth. The ground water is a percolated rain water. well dowser can help you to find a borewell point, you have to find a permanent soultion.
If your neighbouring farmers did not get result, then it is evedent that water percolation is very poor. See below link, in my opinion what these people did was a miracle. They rejuvinated a dead stream and made as it was few years back.
As rightly pointed out by Mr. Sri that - " The ground water is a percolated rain water" u need to understand the Gravity belt in & around your plot area, Water finding survey, plays an important role for locating the Gravity Belt by studying the following five aspects -
Topographical Situations of your plot i.e. the slope, elevations etc.
2) Gelolgical situation of your plot area i.e. the Vertical height & Horizontal disctance of your plot from the Sea Level.
Natural Growth of Vegetations -
Various ecological and environmental interactions are mentioned as indicators of groundwater under the following
headings: (a) phreatophytes, (b) symbiotic intergrowth of trees, i.e. a tree united with another tree species, and
morphological, physiological, and mutational features of plants and plant cover.
The occurrence of water below the surface at depths ranging from 3.43 to 171.40 m with the help of various plants
and grass varieties could be known.
Considering Previous records of the surrounding areas borewells & wells -
Our experts makes a study of all available information on existing wells i.e. information pertaining to the drilling
and construction of wells would be the main sources of information, depth. thickness. and description of rock
formations penetrated: water level variations as successive strata are penetrated; yields from water-bearing
formations penetrated and the corresponding draw downs; the form of well construction; and the yield and
draw down of the well upon completion. variations in yield and water quality and a history of any problems
associated with the well since its completion.
On the elevated plateau tops having good areal extent, local water table develops in top most layers and the wells in such areas show rapid decline water levels in postmonsoon season and go dry during peak summer. In the foot hills zone the water table is relatively shallow near the water courses and deep away from it and near the water divides.
Therefore, the dugwells located in the topographic lows, morphological depressions and on or near the lineaments yield comparatively more water than the located elsewhere, which is particularly true in basaltic terrain.
Drilling of Borewell -
The borewell is drilled by the DTH (Down The Hole) method, In DTH drilling the percussion mechanism – commonly called the hammer – is located directly behind the drill bit. The drill pipes transmit the necessary feed force and rotation to hammer and bit plus compressed air or fluids for the hammer and flushing of cuttings. The fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer, in this process, due to higher ROP (Rate Of Penetration) the borewell with the mediocre yield may end up giving no yield due to the cementation caused due the dust & water (Influxes) on the wall of the borewell.
Therefore, to get the water yield available in the borewell, we have to maintain the Annular Velocity of minimum 3000ft/min for cleaning of the borewell & 5000ft/min for the optimum cleaning of the borewell, by introducing the appropriate amount of Drilling Fluid (Water) to avoid the influxes in the annulus that may restrict the bore hole cleaning with continued Air drilling in the presence of water.
I have tried to explain here the basics for determining the best water location based on the Universal principles of Water.
