Inputs taken from ICRISAT and Ground Inputs taken from ICRISAT and Ground Water Department Water Department

• Based on these inputs a time bound master plan of water augmentation was worked out.

• The activities considered under master plan 1. Rain water harvesting pits,2. New locations for bore wells,3. New location of open wells,4. Planting of trees which requires less water for survival, 5. Locations for new percolation tanks6. Re-usage and Re-cycling of waste water, 7. Channels created for rain water to recharge the under ground

water reservoirs and 8. Massive tree plantation and drip irrigation
