The HSBC Rain Vortex, located at the heart of Jewel, spans seven floors and is a popular attraction for Singapore Visitors.
The HSBC Rain Vortex is the world’s tallest indoor waterfall, standing 40 meters tall and cascading down from the dome-shaped roof of Jewel Changi Airport.
Since it opened in April 2019, this architectural marvel has drawn a lot of attention.
There are structural features built into the building’s exterior to create that even circular flow of water down the Rain Vortex. Outside the dome structure, the “fins” form a network of pipes that channel water to the ring in the center of the oculus. The water is then distributed down the Rain Vortex by the oculus, creating a complete circular effect.
The water runs all the way from the roof to Basement 3, where the catchment area is located. The water stored in B3 is then pumped back up around the building’s perimeter to the oculus, where the cycle begins again.
The water that flows into the Reflective Pool continues down to B1 and B2, forming the Water Skin acrylic column feature.
The greenery that surrounds the vortex in Jewel creates a tranquil environment in an otherwise hectic airport.
