Need suggestion on borewell with no water

Having two borewells as point mentioned by water dividers, but no water.

Hello all,

We have 2 existing borewells as point marked by water dividers. We are not getting water from borewells. One of borewell has been dug upto the depth of 350 ft. We are getting very less water if we run motor once in a week. Please suggest either to go deeper on this or find new water points.

Location: 5 kms from Oragadam Sipoct towards Kanchipuram

Thanks in advance
