I have 6 dry borewells, unsuccessful attempts of trying to tap underground water. I am now using 4 of these borewells for water harvesting. I have built a tank around them and introduced water plants, turtles and fishes into them. During the rain they overflow into the borewell. Also two of them near the house are used to harvest the water that falls on the terrace too.
You can see the borewell pipes inside f these tanks.
The turtle sun bathing
These other two are newly constructed and used for terrace water harvesting.
