Borewell drilling in Hyderabad, Andhra Pradesh : Please advice on the permission required & distance from boundary wall

I have purchased land and is going in for construction in Hyderabad. May I know if any permission has to be taken for digging bore in my Land or if I can call the borewell agency directly and ask them to dig. And also what should be the distance from the neighboring wall to the bore well. Kindly advice?
