How Peru is Netting Water Supplies

from BBC News Online

They look like huge abandoned volleyball nets facing west towards the Pacific Ocean on one of the many hillsides in the Peruvian capital, Lima.

They started as an experiment two years ago and now they are giving a lifeline to some of Lima's poorest residents.

The Peruvian capital gets an average of just over 40mm (1.5 inches) of rainfall a year but what it does not get in showers, it makes up for in fog. For nine months of the year, much of the coastal city is shrouded in sea mist and these nets are being used to trap it.
