Theseus does a great deal of work for Wateraid, and has run several so itTion / fresh water projects in Africa. The one in Burkina Faso (used to be Upper Volta, third poorest country in the world) was the one that truly opened my eyes to what sanitation and clean water mean to people. In one village, they gave him three live chickens to say thank you - an enormous thing for them to give. (I think they were dealt with later...)
Wateraid shop has a gift section, where you can buy everything from taps to the materials for building a loo, and give the donation to someone as a gift, and that's what T asks for for Christmas and birthday presents, since we have everything we need.
