Introduction0 GW Stress ?

0 Low dependency on traditional method.

0 Lower water table Current GW level

0 Underground water pump

0 Power of pump, inversely related to gwl

0 Subsidized electricity to farmers

0 Dilemma

Dilemma0 High Yield ~ Larger land with proper irrigation

0 Irrigation ~ Electric Pump set ~ Electricity(Energy)

0 GW high use of Pump reducing GW Level.

0 Reduced GW require high power pump ~ More

Entitlement calculation

0 GW is being used unwisely.

0 Trend of GW use and energy consumption is found in

various states.0 As : Agricultural consumption = X Kwh*

Number of Consumer = N

Thus : Energy use/Tubewell = X/N

* Total Power transmitted through feeder, consisting ofreal + AT&C losses

Entitlement calculation0 Area of water under surface is variable.

0 MAP

0 GW area = Yha

0 Energy for agriculture = XKWh

0 Energy per ha = X/YKWh/ha

0 This will give us the estimate of energy that will be

required for a particular area, having certain level ofGW.

Data were found from various sources for various utilities of different states like

Punjab, Haryana, Maharashtra, AP, Tamilnadu, Karnataka, Gujrat, MP & Rajasthan.

Karnataka

0 Area = 1,91,791 Sq.km

0 Rainfall = 1779 mm

0

Total Districts / Talukas = 27 districts / 175 Talukas0 Net GW available = 15.30 BCM

0 Annual replenishment = 15.93 BCM

0 Annual Draft = 10.71 BCM

0 Net GW area = 15,30,000 ha

0 Agricultural electricity consumption= 4299.53 MU0 Energy use per Tubewell = 6614.163 Kwh

0 Thus 4299.53 MU/15,30,000 ha = 2810.15 Kwh/ha

1 BCM = 1,00,00,00,000 m3

1 ha = 10,000 m2

1 ha.m = 10,000 m3
