A Chinese company has built a 350ft tall artificial waterfall on the outside of a skyscraper.

The 121-meter-tall Liebian Building, in the city of Guiyang’s business district, has a large tank installed at its base, where four 185-kilowatt pumps lift the water to the top of the fall.

When the sun catches it just right, it creates a huge rainbow within the waterfall which flows down in front of the glass sided building.

The waterfall is managed by Guizhou Ludiya Property Management Co. and is designed to be a tourist attraction.

A spokesperson for the property, Mr Cheng, told Kan Kan News that the main water source is from recycled tap water, rain water or from other channels.

“Our building has a four-storey underground water storage and drainage system, from which the water is pumped and recycled,” Mr Cheng said.

The electricity bill for just one hour of operation is a whopping 800 yuan (£89), he added.

“That’s why we don’t switch on the waterfall every day - only for special festivities in the city,” he said.

And each time, the waterfall is set to run for only about 10 to 20 minutes to save electricity.
