Engineers Without Borders is a growing registered charity dedicated to international development. EWB works with developing communities around the world: a tiny village in the dry heat of Burkina Faso, a town in the altiplano of Bolivia, or a slum in Asia.

Note … EWB needs not only engineers, but also people with a variety of backgrounds.
