There's no questioning the existence of a market for water: the typical human needs between a litre and two a day; India's 1 billion plus populace needs between 1 billion and 2 billion litres a day; even if the number crunching is restricted to the country's 100-odd million consuming classes, the result is a staggering 100-200 million litres a day, or 36.5-73 billion litres a year. In money terms, at Rs 10 a litre, the potential market could be worth between Rs 36,500 and Rs 73,000 crore. A glass of water would be in order now. The market is worth a measly-by-comparison Rs 1,000 crore now, but it is growing at the rate of 40 per cent a year.
