Have you had a glass of water to drink today? How much energy do you think went into treating and transporting that water from its source – probably a lake or aquifer – to your kitchen faucet?
In the United States, 13 percent of the total energy produced each year is used to treat, transport, and heat our water. While that sounds like a lot of energy, getting clean water in the United States is as easy as turning on the tap. In some places around the globe, it is not that simple.

Water around the World: Carrying Water
In the United States and other developed countries, cleaned and treated fresh water is piped directly into our homes – we can turn on the tap for drinkable water any time. However, in less-developed countries, human energy is a necessary part of daily water use. About two-thirds of the world’s families do not have a water supply in their homes and must fetch water in jugs and buckets from wells, rivers, hand pumps, and other public sources. This water is usually collected and carried by women and children.In Asia and Africa, the average woman walks a total of 3.7 miles to collect and carry fresh water home each day. The average weight of water that a woman in Africa and Asia will carry is about 40 pounds! Water is usually carried on the head, back or hips, which can cause severe health problems. On average, a person living in sub-Saharan Africa uses four gallons of water a day, while someone in the United States uses 82 gallons of water a day or more.

How many trips would you have to make if you had to carry all the water your family uses in a day?
