In Fort Cochin, a part of Kochi (formerly Cochin), I saw one Internet cafe, as well as one restaurant, that didn’t sell water in plastic bottles. Instead, they hae big 5 gallon re-usable water bottles (similar to the big water coolers we see in offices back home, or in homes and offices in Arizona and Nevada), from which you can refill your own little water bottle for Rs5/$0.13 per Litre.
A damn fine idea – why didn’t I think of that? We need to suggest that concept in more places around India and around the world!
I do remember a little condo/hotel in Isla Mujeres, Mexico (near Cancun), that put 5 gallon water tank (no dispenser though) in the room.
On an unrelated note, here is a sunset photo in Fort Cochin, with a Chinese cantilevered spider-like fishing net (the unofficial emblem of Kerala) in the foreground:
