So when the 397-foot-tall Liebian Building in Guiyang, China, turned the faucet for the first time, panicked residents called local newspapers to report a catastrophic water leak. The “leak” turned out to be an artificial waterfall incorporated into the building's façade. The 350-foot tall waterfall cascading down the side of the building is probably the tallest artificial waterfalls in the world.
Keeping the monstrous column of water running will cost the building’s owners about $118 per hour, which isn’t very eco-friendly, and has upset some forward-thinking citizens.
“Whose idea was it to put a waterfall on the building? It’s a terrible idea”, one resident told Kanka News. “They should really conserve energy instead of wasting it like that.”
In response, the building’s managers said that the waterfall will run only on special occasions—for just 10-20 minutes at a time—and will use recycled water from rain or the tap.
