Fog Harvesting for Water Resources

1) Water and Health: There are areas around the world with limited access to natural water resources but with considerable proximity to fog. This is where fog harvesting can come into play but capturing fog and producing useful water because without water, people cannot survive.

2) Technology: 

  • Dar Si Hamad has established a 600 square meter installation in Morocco, becoming the largest fog harvesting site
  • MIT was able to develop material that could produce 5 times more water with a mesh made from stainless steel filaments
  • The mesh is dip-coated, causing droplets to flow down to a water basin quickly rather than getting lost back to the environment

3) Stakeholders:

  • Inhabitants of arid regions
  • Manufacturing companies
  • Metals sourcing companies

4) Deployment: 

  • Raise financial support for R&D
  • Have research teams improve the technology further for greater efficiency
  • Work with manufacturer to scale up development

  1. I’ve seen this being used on the coastal areas of South America as well. This comes from a survival technique, similar to using a plastic bag to collect transpiration from nearby plants and trees or from rainwater. My only concern is how does this trapping of condensation, which acts as the main sink of atmospheric water, affect the water cycle and climate?

  2. I think fog harvesting can be proven as a sustainable and scalable solution to water scarcity. But my only worry is about the reliability of the water source for these fog harvesting technologies, because occurrence of fog is very much uncertain. Further, calculation of even an approximate quantity of water that can be obtained at a particular location is difficult. The technology might represent an investment risk unless a pilot project is first carried out to quantify the potential water rate yield that can be anticipated in the area under consideration.
