Recharge a failed borewell and re-activate it.
The seasonal changes in the climate affect out day to day life. Unavailability of drinking water in the summer and abundant water in the winter is a common problems which leads to an imbalanced ecosystem. During rainy season, one searches place to drain the excessive water and during summer searches for water and digs bore-wells and suck the underground water. This water is neither returned to ground nor recharged. The underground doesn't get affected by the seasons that exists over the surface. The water taken from it should be returned back. One keep on sucking water makes it to fail. A failed borewell therefore is my evidence to balance the ecosystem. By creating filters and a trench over a failed borewell, and making channels from a place where water stays during rainy season, the excessive water goes back / recharged the underground, thus enabling flood disposal and save water for summer.
