Funny how the things you now take for granted like water and electricity in a big western country are not that granted everywhere! To be honest, I never paid that much attention to the price of utilities when I was in Paris, because from the very first times I moved into my own place I knew it was something you had to pay and that it was not very expensive. Now that I am in Malta, I had to look into all this with much more attention for they have a different system here: the more you use electricity and water, the more you pay - that is the more each kwh and cubic meter is expensive. This to encourage households to be "reasonable". These bottles are part of the Eau de Paris collection, that you can find at the Pavillon de l'eau in the 16th arrondissement.
