Delivering good water, sanitation and hygiene services not just to a few people for a while but to everyone forever requires a fundamental shift in the way we all think and work together.

Patrick Moriarty an engineer with more than 20 years of experience building sanitation systems in South Asia and Africa, and CEO of IRC explores what can we learn from people who are building systems in third world countries in this TEDx Event.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
