Gujarat is almost surrounded by the ocean, it's an endless supply of water. You can build very low tech and very cheap systems to evaporate and condensate fresh water. Black container with salt water, a few reflective panels to concentrate the sun, tube to guide the steam/vapor into another container with the fresh water. It can be VERY cheap.
There are probably more efficient membrane-based solutions, but probably more expensive.

- bufferoverflow 9y agoYou don't have to. Gujarat's population is 63 million. And most of them get enough water to survive already. Unless you meant to supply the whole country from Gujarat, in which case it's a straw man argument.
