What are the different techniques of water harvesting?
Recharge pit In alluvial areas where permeable rocks are exposed on the land surface or are located at very shallow depth, rain water harvesting can be done through recharge pits. The technique is suitable for buildings having a roof area of 100 sq. m. These are constructed for recharging the shallow aquifers.
