Jal Shakti Abhiyan Best Practices … by in Tiruvannamalai District Tamil Nadu K.S.Kandasamy, District Collector.
Water Bank • Registered under TN societies Registration Act formed under the chairmanship of District Collector • Officials, NGO’s, volunteers and farmers are members • An effort to converge schemes like MGNREGA with CSR , Donors to rejuvenate the water bodies by involving the local volunteers • Hereby we are extending material and labour support to the volunteers • There are 113 voluntary groups registered and renovated 327 water bodies in last 2 months
“Auto Off Switch” for OHT water pumps • To avoid wastage of water in community overhead tanks located in remote areas, automatic cut off switches have been installed • Pump turn off once tank is filled and when borewell dried • It has twin benefits of saving water and improving the motor life
Mulching • Mulching is a cultivation technique of covering the soil with biodegradable plastic sheet around root zone to generate conducive soil condition • The plants are irrigated by drip irrigation under this method • Banana, Water Melon, Musk Melon, Papaya and Brinjal are most suitable crops • This saves 30 to 40% water against conventional irrigation method • It also controls weed, improves yield by 20% and advances harvest time • Now 75 Hectares under mulching cultivation in the District

Pot Irrigation • A traditional technique for watering the plants • A clay pot is earthed close to root zone of plants • A small hole is made at the bottom of the pot towards roots and a coir thread is inserted through which water let off to root • 35,000 saplings are being planted using pot irrigation • This method helps in daily watering to once in 4 days
Micro Irrigation • Drip irrigation, rain gun, sprinklers and rain hose are extensively used • Farmers are supported under the PradhanMantriKrishiSinchayeeYojana • Drip irrigation now used in sub soil level which helps less water usage and also fertigated at root • Extensively used for sugarcane crop and saving more than 50% of the water • Sprinklers and Rain guns will save more than 60% of the water • Rain Hose Irrigation more suitable for flowering plants and control insect population in the field • 16,820 Hectares of land have been brought under Micro Irrigation in the last three years in the district

Water Budget • Is prepared for all the villages by taking water demand and supply • Ground water data and surface water taken and compared with water requirement for various crops in the village • Water gap is derived and with the help of 3D contour map various water saving and harvesting techniques are planned for each village • Water Conservation and watershed Developmental measures are suggested to bridge the gap between the demand and supply
Crop Diversion • Farmers are used to cultivate paddy and sugarcane in assured irrigated areas • Paddy and Sugarcane requires 12000 KL and 16500 KL of water per hectare respectively from sowing to harvest • Thereby farmers are able to rise one crop a year then land fallowed for rest of the period • By intensive persuasion around 5000 hectares which are usually under paddy and sugar cane are diverted into less water intensive crops like Groundnut, Black gram and Green gram • These crops require on an average 7340 KL of water per hectare now farmers are able to rise two crops in a year
JSA Interventional Outcome Immediate visible Outcome • More awareness among the public to save rain water • Reduction in wastage of water at community • More public participation in maintaining water bodies and recharging ground water • More fallow land are brought under cultivation • Increase in water holding capacity in water bodies • Increase in soil moisture
JSA Interventional Outcome • Productivity will be more (Rice 7.04L MT) • Aggressive technology & Machinery application in agricultural practices by farmers • Shifted 5000 Hectares from single crop to double crop • Increase in income to farmers • More green on earth will be seen Assured Future Outcome
