Abstract- India is one of the wettest nations. However, few states including Tamil Nadu are reeling under water miseries due to lack of effective water security pathways. However, it is possible to additionally generate or, save 28.32km3/1,000TMC of water and enhance to 74.84km3/2,643TMC from the 46.52km3/1,643TMC in Tamil Nadu by water management. Even then, the per capita per annum water deficit will be 684m3(59.76%) in 2050 comparing the Falkenmark Water Stress Indicator at 1700m3. Therefore, the main option for permanent water security to this state is sharing the unutilised 1,728km3/61,023TMC of water let into the sea in India.

Key words- Water scarcity, Water Management pathways, Action Plan, Sustainable water resources development
