Desperate measures to conserve water in South Africa’s capital have had little effect, with taps are expected to run dry in less than 4 months.

The taps in Cape Town are predicted to be turned off on April 12, when the reservoirs drop below the minimum levels needed to provide water safely.

“Day Zero” as officials have called it, will follow three consecutive years of drought, and will mean Cape Town will be the first metropolis in the world to run out of water.
