Desalinating seawater can guarantee water security 

Public water strategy ought to incorporate usage of ocean water assets for all encompassing improvement of nation's water assets 

India has been seeing serious disintegration of its water table. Expanding extraction of groundwater has likewise influenced its quality. Consecutive storm disappointment in pieces of India has prompted incredible difficulty and drinking water must be shipped by rail to Latur in Maharashtra the previous summer. We are lucky that India is invested with tremendous seawater assets traversing over twelve states and association domains. Guaranteeing supply of cleansed ocean water through devoted organization in the area would help individuals hugely. Be that as it may, there is no notice of saddling ocean water assets in the draft National Water Policy structure bill, 2016. It is a typical discernment that transformation of ocean water is expensive, however this is changing with headway of innovation in the field. Push on exploration and innovation upgradation has helped in lessening cost.

Water from the desalination cycle is reasonable for generally homegrown, modern and rural employments. Seawater desalination is progressively turning into an indispensable choice for reducing serious water lack the world over. Israel presently gets 55 percent of its homegrown water from desalination and that has helped transform probably the driest nation into the unlikeliest of water monsters (Scientific American: "Israel demonstrates the desalination time is here" by Rowan Jacobsen July 29, 2016). Australia, North Africa, Caribbean Islands, Middle East, South Africa and USA are a portion of different nations that have set up desalination plans for homegrown use. As per UN World Water Development Report, 2014 in excess of 17,000 desalination plants are presently working in 150 nations around the world, and limit can twofold by 2020. Global Desalination Association guarantees that desalination produces 21 billion gallons of water for each day providing water in parched districts. 

In India, various desalination plants have been set up in states like Tamil Nadu, Puducherry and Andhra Pradesh. The biggest seawater desalination plant through opposite assimilation (RO) measure providing 100 million liters of new water to Chennai has been set up. According to Desalination Association of India, there are in excess of 1,000 film based desalination plants of different limits going from 20 cubic meter (cm) every day to 10,000 cm/day in the nation. 

Instances of innovation across the world 

Desalination advances are progressing quickly and ocean water would now be able to be recovered by going it through RO films. In opposite osmonsis, water is singled from a saline arrangement with broke up salts by streaming it through a water porous film. The saturate (fluid moving through water-porous layer) is urged to move through the film by the weight differential made between pressurized feed water and the item water. The significant energy necessity is for the underlying pressurization of the feed water. Nanotechnology based arrangements, particularly nano-metal impetuses, are picking up conspicuousness in giving answers for reduce water quality issues. Israel has come out with a few best in class advances. In the US, the biggest plant in the Western Hemisphere with best in class RO office has been worked close to San Diego. Analysts of Israel's Zuckerberg Institute for Water Research have made achievements in film innovation making desalination significantly more efficient(Scientific American:ibid). India's Department of Atomic Energy (DAE) has created indigenous desalination and water refinement innovations. The nation's RO desalination plants basically expect to meet modern and consumable drinking water prerequisites. 

Is it monetarily feasible? 

The expenses for desalination have diminished throughout the long term. Water created by desalination cost simply 33% of what it did during the 1990s. Israel's Sorek plant, which is the biggest on the planet, can deliver 1,000 liters of drinking water for 58 pennies (Scientific American:Ibid). As per Desalination Association of India's gauge, creation cost for ocean water desalination plant fluctuates between Rs 40 to 50 for every cubic meter and the creation cost of desalted water from profluent differs from Rs 15 to 50 for each cubic meter. Likewise, the creation cost of a harsh water desalination plant ranges between Rs 10 to 15 for every cubic meter. As indicated by DAE, on a normal, the expense of change of ocean water into desalinated water is around 10 paise per liter water produce. (Source: Reply given by Minister of Science and Technology in Rajya Sabha 23.7.2015). The energy cost which is a significant part could be cut down further if sun based, wind or tsunami are used.

Public water strategy ought to incorporate use of ocean water assets for all encompassing improvement of nation's water assets. The expense of ocean water change plants might be shared by Center, states, neighborhood bodies and privately owned businesses. Under the public authority's Sagarmala venture where setting up of significant improvement ventures have been thought about in waterfront states, groundwater based advancement should be debilitate. All things being equal, treated ocean water should be utilized. Service of Urban Development intends to create 100 shrewd urban communities in the nation. Desalination plants can be essential for guaranteeing normal water supply. Thane Municipal Corporation, which has been chosen for the brilliant city venture, has proposed to desalinate spring water and use it for drinking purposes. The desalination plant is accounted for to be set up during the year 2017 and on open private association mode.
