Updated figures from Levi Strauss & Co suggest production of its Water
To put it into context, that's the equivalent of china led lights drinking water for the whole of New York City or London for over a month, 308 Olympic swimming pools, 3 billion 8-ounce glasses of water, 4.5 million bathtubs, or 25 million average-length showers.

The company launched the WaterLED street light wholesaler success that it will maker another 9m units in spring 2014 alone - saving another 71m litres of water.

Levi's also points out that the production of its jeans is just the start of the conservation process, suggesting that consumers would save another 14 litres of water by washing their jeans once every two weeks, instead of once a week. That's five days of drinking water for one person.

Last month Levi's said it has developed a technology that uses 100% recycled water in the finishing process - and has so far produced 100,000 pairs of women's jeans using the new system, LED g24 which it also plans to roll out at its supplier factories worldwide.

The figures were released ahead of the UN's annual World Water Day on 22 March, which is this year focusing on water and energy.

An estimated 100-150 litres of water is needed to process one kilogram of textiles, putting pressure on the industry to adopt advanced water and wastewater treatment technologies, as well as reduce overall water footprint.
