Not to mention that, if you believe the typical marketing bullshit, your bottle water is probably sourced from the Alps or some stream in the arse crack of New Zealand and then transported across the globe for however long that takes, until it finds its way to a store and then to your lips. Brita filters (or any other filters/jugs) have their own environmental costs as well but you can chug through a decent amount of tap water before you need to replace one of those. Couldn't live without one of those in Barcelona (unless I wanted to down a glass full of limestone), and was much more useful than lugging back a few huge jugs of bottled water every few days. Back in the UK, not a single reason to buy water in a bottle unless you're outside and in a pinch.
