Water is tasteless but for private equity in India, it seems to be the flavour of the season. Last year, Singapore-based CLSA Capital Partners invested ₹83 crore in waste water treatment company Earth Water Group and in July this year, invested ₹55 crore in Gurgaon-based Luminous Water Technologies. A couple of months ago, Matrix Partners’ put in ₹22 crore in water purifications solutions provider Waterlife India. And in June, Capvent picked up a 51% stake in Chennai-based water engineering company Morf India.
