The world's tallest artificial waterfall cascades from a 121-metre-high skyscraper in southwestern China.

The impressive video was filmed in the city of Guiyang in Guizhou Province on May 5th.

The waterfall, originating from a height of over 100 metres, spans a width of about 10 metres and drops more than 20 stories.

This is the world's tallest artificial waterfall, with the building standing at 121 metres and the waterfall designed to be 108 metres high. The water used is recycled from underground sources, including rainwater and other channels. A storage and drainage system on the underground fourth floor supplies the water, which is pumped up by four large 185-kilowatt pumps, creating this urban waterfall spectacle.

The waterfall operates on a recycling system and is only turned on during major holidays and events, with scheduled openings once in the morning and once at noon, each lasting about 20 minutes. The operation costs approximately 800 yuan (£86.5) per hour in electricity.

The waterfall has become a popular attraction, delighting many residents and tourists. A spokesperson for the building explained that the primary purpose of the skyscraper, which houses an ultra-luxury hotel, is to attract guests, and the 100-metre waterfall is a significant draw.

The waterfall and its reservoir do not compromise the building's safety, as the water is collected and reused, ensuring no waste of water resources.

5月5日，在贵阳市观山湖区烈变广场，一座现代化摩天大楼似乎漏水了，只见百余米高楼上部喷出巨大水流，在玻璃幕墙外侧倾泻而下，水帘宽度十米左右，高度二十多层楼，底部水雾在阳光下还呈现彩虹。
据了解，这是当前世界最高的人造瀑布，楼高121米，瀑布设计高度108米。用的水是回收的地下自来水，一些下雨的水或者其他渠道来的水，地下负四层有储水排水系统，景观瀑布使用4台185千瓦的大型抽水泵，将水从负四层储水池抽上去，造就了城市瀑布景观。
人造瀑布的水是循环使用的，只在重要节假日和大型活动时有计划性开放，一般上午开放一次，中午开放一次，每次开放约20分钟，每小时耗电约800元。
在城市中艳遇瀑布，也给不少市民和游客增添了满满的幸福感。
该大厦一名负责人介绍，首先，这座大厦建成后，其主要目的是打造一座超五星级酒店，作为高级酒店，大厦自然需要一个能够吸引客户的噱头，而百米瀑布无疑就是最好的亮点，能够给酒店带来大量客户，其次，大厦的瀑布与蓄水池并不会影响大厦整体的安全，所以外界也没有必要担心，同时瀑布水会落入裙楼中，然后继续流入蓄水池，做到重复利用，并不会大量浪费水源。
