We’re doing our part to conserve—particularly in California, home of our headquarters and a state struggling with a years-long drought and water-use restrictions. We continue to incorporate drought-resistant landscaping, drip irrigation and water-saving fixtures and devices across our facilities. In 2010, we used 122.6 million gallons of water at our San Diego facilities, compared to a total of 131.2 million gallons in 2009, a savings of more than 8.6 million gallons. Additionally, by carefully managing our cooling tower water-treatment program, we saved 18.08 million gallons of water as compared to 2009’s savings of 17.8 million gallons.

2010 Water Usage (million gallons, San Diego, CA, facilities only)*

We have been proactive in using available reclaimed water, thus reducing our usage of potable water. In 2010, we saved more than 2.8 million gallons of potable water in our cooling towers and 14.0 million gallons of potable water used for landscape irrigation by using reclaimed water. We also completed efforts at our San Diego facilities to implement reclaimed water for the central plant cooling tower—an effort that will save more than 28 million gallons of potable water annually.
