Water Crisis in the Maldives: Desalination and Rainwater Harvesting as Solutions

The video discusses the water crisis on Difushi Island, where seawater has contaminated the freshwater table, making it unusable. As a short-term solution, desalination units using reverse osmosis are deployed to provide drinking water. However, these units are temporary, and a long-term solution involves rainwater harvesting. By collecting monsoon rains in water tanks, the islanders can have a sustainable source of freshwater.

How much rainwater can the tank mentioned in the text hold, and for how long can it supply a family of four?

What is the significance of storing rainwater for the inhabitants of the islands?
