Many of Peru's grittiest slums can only dream of access to water. But thanks to a German NGO, simple technology and hard work, some humble homes are the first to use plastic netting to harvest water from the fog cloaking the night sky.
In sprawling settlements like Bellavista del Paraiso -- a dusty clutch of streets on Lima's south end named "Beautiful View of Paradise" with some eye-popping optimism -- there is no running water.
There is no well.
Buying water, trucked in by resellers, costs nine times what it does in richer urban areas, precisely in places where no one can afford it.
And Bellavista's more than 200 residents are used to making do without water; they are among the stunning 1.3 million of Lima's eight million people who have no access to water.
"Really, it just seemed like it would be impossible to catch fog with plastic netting, and that it would turn into drops of water," said Noe Neira Tocto, the mayor of the slum which lies just inland from the Pacific.
"We are the very first to have fog-catchers in Lima's poor neighborhoods," he said, proudly showing off a system that works with a net that looks a lot like volleyball netting.
"We have five panels that are eight meters by four meters," perched on the mountaintop above, he explained. "With them we are able to collect up to 60 liters per night in wintertime."
