APGWD
 Shallow water table
 Existence of springs and flowing
wells
 Less dependency on groundwater
for irrigation
 Recharge rate is more, Soil
health is good
APGWD
 More area under groundwater irrigation, high water
requirement crops, flow irrigation practices etc., created stress
on groundwater resources resulted in
 depletion of water table
 decrease in well yields, drying up wells
 consumption of more power for lifting same quantity of
water
 deterioration of water quality etc.,
 Reduction in Recharge rate due to concretization, change in
land use practices etc.,
 Deterioration of Soil health due to changed agriculture
practices (high use of fertilizers and pesticides, multipleAPGWD
crops
etc., )
NEERU-CHETTU MISSION:
 Drought proof the State
 Control the Wastage of water to the Sea
 Water Conservation and Management
 Soil moisture conservation
 Watershed treatment
 Rainwater Harvesting Structures
construction
 Catchment area treatment
 Degraded lands treatment &
Increase the area under green cover
 Increase the production and productivity
 More productivity per drop of water
 Improve the groundwater recharge
 Desilting of tanks and restoration of tank
cascades and irrigation systems
 Conjunctive use of Surface water &
Groundwater
 More area under MIP (Drip & Sprinkler)
 Integrated Plans for sustainability of
Irrigation sources
 Improve the Water use Efficiency,
Reduce the gap ayacut
 Promote Solar and other non conventional
energy sources
 Encourage Participatory Irrigation
