Israel is doing it and pioneer in that anukunta..

Israel , Arab countries are doing it but its not a mass scale that we can supply to municipalities. 

It is still on a small scale, I would say for drinking water purposes and that too it is still in hundreds of liters, but the requirement is millions of gallons. 

It would still take some more time for the technology to develop and use efficiently for the cost to come down heavily.

Yes Chennai lo there is plant 

Inka why late atleast use it for summer 

But ocean water will get more salty 

bro can u explain this..u mean to say summer lo ocean water inka salty untai antunnava?

Yeah, chennai has one desalination plant set up with israeli consortitum and that was built recently...i remember 3-4 years back..

and again, even this one is  an alternative as capacity is not huge and can only supply for drinking water requirements...

heavy cost of building,maintenance and operation...

The world’s largest and cheapest reverse-osmosis desalination plant is up and running in Israel.

Availability: now

• by David Talbot

On a Mediterranean beach 10 miles south of Tel Aviv, Israel, a vast new industrial facility hums around the clock. It is the world’s largest modern seawater desalination plant, providing 20 percent of the water consumed by the country’s households. Built for the Israeli government by Israel Desalination Enterprises, or IDE Technologies, at a cost of around $500 million, it uses a conventional desalination technology called reverse osmosis (RO). Thanks to a series of engineering and materials advances, however, it produces clean water from the sea cheaply and at a scale never before achieved.

Megascale Desalination

• BreakthroughDemonstrating that seawater desalination can cost-effectively provide a substantial portion of a nation’s water supply.
• Why It MattersThe world’s supplies of fresh water are inadequate to meet the needs of a growing population.
• Key PlayersIDE Technologies
  Poseidon Water
  Desalitech
  Evoqua

Worldwide, some 700 million people don’t have access to enough clean water. In 10 years the number is expected to explode to 1.8 billion. In many places, squeezing fresh water from the ocean might be the only viable way to increase the supply.

The new plant in Israel, called Sorek, was finished in late 2013 but is just now ramping up to its full capacity; it will produce 627,000 cubic meters of water daily, providing evidence that such large desalination facilities are practical. Indeed, desalinated seawater is now a mainstay of the Israeli water supply. Whereas in 2004 the country relied entirely on groundwater and rain, it now has four seawater desalination plants running; Sorek is the largest. Those plants account for 40 percent of Israel’s water supply. By 2016, when additional plants will be running, some 50 percent of the country’s water is expected to come from desalination.

The traditional criticism of reverse-osmosis technology is that it costs too much. The process uses a great deal of energy to force salt water against polymer membranes that have pores small enough to let fresh water through while holding salt ions back. However, Sorek will profitably sell water to the Israeli water authority for 58 U.S. cents per cubic meter (1,000 liters, or about what one person in Israel uses per week), which is a lower price than today’s conventional desalination plants can manage. What’s more, its energy consumption is among the lowest in the world for large-scale desalination plants.

The Sorek plant incorporates a number of engineering improvements that make it more efficient than previous RO facilities. It is the first large desalination plant to use pressure tubes that are 16 inches in diameter rather than eight inches. The payoff is that it needs only a fourth as much piping and other hardware, slashing costs. The plant also has highly efficient pumps and energy recovery devices. “This is indeed the cheapest water from seawater desalination produced in the world,” says Raphael Semiat, a chemical engineer and desalination expert at the Israel Institute of Technology, or Technion, in Haifa. “We don’t have to fight over water, like we did in the past.” Australia, Singapore, and several countries in the Persian Gulf are already heavy users of seawater desalination, and California is also starting to embrace the technology (see “Desalination Out of Desperation”). Smaller-scale RO technologies that are energy-efficient and relatively cheap could also be deployed widely in regions with particularly acute water problems—even far from the sea, where brackish underground water could be tapped.

Earlier in development are advanced membranes made of atom-thick sheets of carbon, which hold the promise of further cutting the energy needs of desalination plants.

After purification left water will contain more salty content which they will send back to ocean

If this was the solution, then there would be no shortage of water.

removing salt from ocean water or desalination process is a very complex process and it requires heavy energy, the kind of which only Arab countries can only be able to afford at this time.

Chala expensive process and high energy consuming procedure. Such a things is still 20 years away from mass usage.
