Vintners make wine with the power of waste water

Water is precious, especially for a vintner. Making a gallon of wine requires anywhere from a few dozen to a few hundred gallons of water.The Clois du Bois winery in Sonoma County, Calif., spends hundreds of thousands of dollars each year just powering the pumps that clean its waste water. But they are trying a new system that will clean up their waste water and turn it into power.
