QUESTION
Borewell construction -water scarcity

I live in Chennai. Our borewell is not yielding water and many of my neighbors face the same issue. plumber suggested us to drill another borewell. We do not have space , as our first floor extends to cover the entire plot area, hence the only way which our plumber suggests is to drill hole in the roof in order for the drilling machine to fit. Is there any other option instead of drilling a hole in our roof? Appreciate the help.
