The tallest man-made waterfall in the world is located at the Liebian International Building in Guiyang, the capital of Guizhou province in Southwest China. This staggering architectural feat features a waterfall that cascades 108 meters (approximately 354 feet) down the facade of the 121-meter skyscraper. It is powered by four massive pumps that draw water from underground tanks filled with recycled rainwater and runoff, creating a spectacular urban landmark. However, due to the immense electricity costs—roughly 800 yuan (about $115) per hour—the waterfall is only operated on special occasions and for short durations, usually about 10 to 20 minutes at a time. While the HSBC Rain Vortex at Singapore’s Jewel Changi Airport is often cited as the tallest indoor man-made waterfall at 40 meters, the Liebian waterfall holds the global record for total height in a man-made structure.
