Energy - How Much Water Does An Average Person Use Each Day?
The standard for water usage is different depending on where you live.
The U.S. leads the world in water usage, about 575 Liters per person per day. The majority of that water is used for flushing toilets, baths and showers, and washing hands and other objects. Water is cheap and easily obtained in the U.S., and so isn't considered a luxury item.
As of 2006, a person living in Mozambique used only 4 Liters of water each day. The majority of that was for drinking.
The average of 30 countries tested around the world as of 2006 is 165.7 Liters per person, per day. The water poverty threshold is 50 Liters per day.
It is hard to obtain sterile water in many places around the world, and what water is available is considered a necessity of life, and so is not used for bathing or cleaning. The top ten water-using countries use about 6 times as much water as the bottom 20.
