In less than 3 months, a major international city will likely run out of water

A few days ago, city officials had said that day will come on April 22. This week, they moved up the date to April 12.

Cape Town is South Africa's second-largest city and a top international tourist draw. Now, residents play a new and delicate game of water math each day.

They're recycling bath water to help flush toilets. They're being told to limit showers to 90 seconds. And hand sanitizer, once somewhat of an afterthought, is now a big seller.

"Unwashed hair is now a sign of social responsibility," told resident Darryn Ten.
