Just locate you in the map and look around to find a free drinking fountain.
Are you walking near the Roman Forum or the Colosseo or somewhere in the World? You need water? Just locate you in the map and look around to find a free drinking fountain. But if your are in Rome and the battery is down just buy the book "I Nasoni di Roma" by Fabrizio DiMauro - Editrice Innocenti
