Levi’s Water<Less jeans collection, designed to reduce water used in the finishing process by up to 96 percent, has saved over 770 million liters of water since its launch in 2011, the company announced.

That figure is equivalent to the drinking water used in New York City in a month, or 308 Olympic-sized swimming pools, Levi Strauss said.

This spring the company will make 9 million units of the Water<Less jeans, saving 71 million liters of water.

Last month Levi’s said it is testing a process for using 100 percent recycled water in parts of its production. The process is being used in one of Levi’s Chinese factories, which bleaches, dyes and stone-washes garments.
