One of the aims of WeTap is to "remind people that drinking tap water from reusable containers is the cheapest and most environmentally-friendly way to stay hydrated." WeTap is described via Insteading.com as:
"...an app that will allow smart phone users to add the location, condition, and quality to a national database of fountains. The uploaded data, and a photo, will be accessible to WeTap users who are looking for a drinking fountain in that area."In addition, not only do the makers of the app want to encourage cities to install more fountains, but they hope this database will push municipalities to repair and maintain current fountains since users will be able to post photos.
WeTap is still in beta-testing, but if you're interested in helping out with the mapping and getting them started in Arizona or wherever you might be reading this from, check here.
Are you an iPhone user? While it seems there is nothing quite like WeTap yet, according to Treehugger, there are a couple of apps you may find interesting:
"TapIt in New York helps iPhone users find participating restaurants, cafes and other locations where they can refill their reusable water bottle, and GlobalTap is working on getting clean water bottle refilling stations set up in the Bay Area of California, with hopes of spreading nation-wide."
