I am currently digging a 6.5inch borewell in Hennur area in Bangalore. Water diviner has said i need to go to 700ft in order to get 2inch water yield. However the borewell company has told me that at 500 ft I have achieved a 1inch yield and that i should stop drilling at 550ft. They say that if i go further down then the yield will decrease. At the moment i cannot see any water coming out and they are saying that is because it is all evaporating due to high temperature.
Can you please advise me on when i should stop drilling? What should i be looking out for during drilling.
