That's a really great point, and bottled water is actually the fastest growing segment of private water in India (growing 30% year over year). My co founder and I have been living in India for the past 6 years and we both own personal home water filters and carry around a reusable water bottle. We are fans of companies like Unilever who are trying to produce low cost water filters for emerging markets. We think that if we can get the cleanest, cheapest water to people, and by eventually partnering with water filter companies, we can tackle the bottled water problem.
