Not just water, but there's groups like Heifer International, and Samaritan's Purse, which allow you to buy farm animals like baby chicks, ducks, goats, etc. that will be given to poor families in Third World countries.
Instead of buying a generic gift basket for your wealthy relative, do something like that, or
- help dig a well in Africa
- help stock a fishpond for a starving community
- provide an education for a kid in Iraq
Most of the charities I linked here are Christian organizations, but there are plenty of others like Heifer that are secular-based. Imagine giving a Trio of Rabbits, or a Flock of Chicks - how fun is that?!
