Water in West Africa is precious.
There's only one water point for each village where you can get some water. In Zanzibar I also saw it so it's probably the African thing, sorry if I sound stupid (maybe you already knew about all this) but it was the first time in Africa ^^.
Local women has to carry such a huge bowl of water on top of their head every day. I don't think I can do it, maybe I should feel happy.
Drinking water is sold mostly in such plastic bags. This isn't anything new, in many Latin American countries, you see such thing as well. But difference is in West Africa, you won't find bottled water at all, all you can get is in plastic bags. Except I once tried one that tastes like chemical sanitizer, most of them taste alright.
Don't take anything for granted..
