From Poop to Potable

Bill Gates challenged a group of engineers to come up with an affordable way to get rid of disease-spreading sewage in developing countries where getting rid of waste is too costly.  The engineers rose to the occasion and developed a process called Omniprocessor, which makes drinking water from sewage.

Gates says “The water tasted as good as any I’ve had out of a bottle. And having studied the engineering behind it, I would happily drink it every day. It’s that safe.”
