Towards the use of Rainwater and Fog Water Harvesting Systems – A Sustainable Approach

Abstract

An increase in population and rapid rise in water consumption has put the world's water supply in threat. Supplies of fresh water are depleting specifically in the arid regions. Considering the increasing need for clean water, it is necessary to develop efficient water harvesting methods. In this regard, this study provides an overview of the use of rain and fog water harvesting systems. These systems have attracted interest as potential sources of water due to their accessibility, affordability and ease of construction. Particularly, fog harvesting is an effective method in misty environments where collection of tiny airborne droplets, droplet fusion, conveyance, and storage are major processes. The outcomes of this study are helpful for upcoming researchers, water engineers, organizations, policymakers and governments to assist sustainable water management.
