Capturing water from fog - on a large scale - could provide some of the driest cities in the world with drinking water. This is what researchers in Chile have concluded after studying the potential of fog harvesting in the desert city of Alto Hospicio in the north of the country.

Fog harvesting is a relatively simple process. Mesh panels are hung between poles, and as moisture-laden clouds pass through the mesh, water droplets form and are channelled into pipes and storage tan

As cities grow, so does their demand for water, often surpassing the capacity of traditional sources. Many fast-expanding urban areas in dry regions struggle to supply their residents with enough clean water.

One of the driest places in the world is Chile’s Atacama Desert. It receives less than a millimeter of rainfall […]

Fog harvesting may provide a crucial water source for people living in some of the planet’s driest regions. By capturing moisture from passing fog, this technique gathers droplets and channels them into storage,

It's not a one-stop solution to water shortages, but it could help supplement other harvesting and conservation methods.

In a nutshell Scientists discovered that fog collection could provide up to 10 liters of water per square meter daily in areas surrounding Alto Hospicio, Chile, enough to help supply the city’s 10,000 informal settlement residents who currently rely on water truck deliveries.
