Hong Kong has too little and too much water at the same time. On the one hand, the city has very few reliable sources of drinking water as there is no major river or natural lake. On the other hand, tropical storms make it one of the wettest cities in Asia with frequent flooding and waterlogging.


To save precious freshwater, Hong Kong uses seawater for toilets utilizing a special water pipe attached to almost every toilet in the city. A massive network of pipes carries water into buildings exclusively for toilet flushing, reducing freshwater consumption by 20 percent.

For all the rain, Hong Kong has built a massive underground storagge tank underneath an area for recreational activities which is covered in lush greens.
