“TapIt was founded in 2008 to give New Yorkers free access to clean sustainable water on the go. TapIt is a water bottle refilling network. Café owners sign up as ‘partners’ to provide water to the public. The public can find ‘water on the go’ with TapIt’s search and mapping features (PC, Smartphone, iPhone Application).”
It’s a great idea, being able to search where you will be heading during in the day and finding water hot spots. Though here in Australia if cafes refuse to provide free tap water there in huge trouble as it is something they have to provide customers.
