Borewell water insufficient in an apartment in Bangalore, Karnataka - Is re-drilling the best option?

Hello Sir,

I have moved in to a new apartment at AECS layout , Bangalore.  The water from the bore well is not sufficiant and we are depending on the tanker for the water. I was keen to know if we can do anything with the bore in its current stage to improve the situation ?

Can we drill the same bore further ??

Please suggest.

Thanks
