Have 7 borewell of 1000 feet each, only 2 are working - Need help to adopt a scientific approach to arrive at new borewell point

We have a college in Nelamangala in Karnataka, where we have already drilled 7 borewells each more than 1000 feet.  Out of these only 2 are working with a minimum water source of about 1/2 inch according to the mechanic. I want to drill one more bore well now. I want to adopt a scientific approach to make an assessment of underground water and then arrive at the point that will yield atleast 2 inches of water.  Is there anyone who can help me in this regard.
