Answer:
- Desalination
- Rain water stored in cisterns
- Recycling
Explanation:
Santorini is a very beautiful island in Greece that consistently ranks amongst the most beautiful places in the world.
They have a water shortage problem in the island and have resorted to investing in desalination plants in the island to make ocean water safe to use.
They also store rainwater in cisterns which are large waterproof receptacles that can hold thousands of cubic meters of water at their maximum.
Finally the people are very conscious of using water in the island such that they manage the water effectively. They reuse when they need to and recycle water as much as they can.
