World’s Large Cities Move Water Equivalent to Ten Colorado Rivers to Meet their Annual Water Needs. As cities grow in population and economic activity, they reach further and further out to find water to meet their needs.

World’s Large Cities Move Water Equivalent to Ten Colorado Rivers to Meet their Annual Water Needs

Now, a new study has estimated that collectively the world’s large cities, defined as those with at least 750,000 people, move 504 billion liters (133 billion gallons) of water a day a cumulative distance of some 27,000 kilometers. Positioned end to end, the canals and pipelines transporting that water would stretch halfway around the world.

The volume transferred annually is equivalent to the yearly flow of 10 Colorado Rivers. Many large cities tap supplies not only in their own watersheds, but also in others far afield. Los Angeles, California, with imports of 8.9 billion liters per day from distant rivers, ranks first in the world in cross-basin water transfers, according to the study, published this week in the journal Global Environmental Change.

National Geographic's water footprint calculator is designed to give U.S. residents an estimate of the water they use on a daily basis.

Water Calculator Methodology

This includes direct use at home through toilets, taps, and hoses, but also the water embedded in the production of food crops, electronics, paper products, electricity, transportation fuels, and more. The calculator is meant to be an educational tool that gives users a rough estimate of how much water it takes to keep their daily lives afloat.

It is not meant to be a definitive and granular analysis. We give you an individual footprint for household water use (indoor and outdoor), for your diet, your energy and transportation choices, and for the material goods and services you rely on or treat yourself to—from visiting the hospital to purchasing a new TV. In all but the outdoor section, the footprint relies on a baseline average that your responses are either added to or subtracted from. The Hidden Water We Use. Tibetan Plateau.

China’s Ministry of Environmental Protection says that only half of the water in China’s rivers and lakes is safe for drinking. Pollution is so bad that one-quarter of the country’s water is not safe to be used in industry or agriculture. Even without pollution, China would have a water crisis.
