What to do if agriculture borewell fails?

Can we restore the water in rainy season, if agriculture borewell fails?

1) If Agriculture borewell fails, can we restore the water in rainy season to recharge the same borewell. Can a failed borewell be converted into water source borewell to utilise the water in needy days to feed the plants.

2). For three acres of land of plants with agro-forestry method (nearly 4000 plants), what is the agri-pond size and its maintenance process for long term agri activities.

Thanking you,
