Virtual Water
Conservation is an important piece of preserving our precious water resources. Before we learn how much we need to conserve, it is helpful to know how much we consume. How can we determine the quantity of water that is connected to produce or a product? The answer is “virtual water”.
In 1993, Professor John Anthony Allan of King’s College, London, helped improve the way we think about water by calculating the amount of water that goes into the prodcution of a product from beginning to end. In fact, he was named the 2008 Stockholm Water Prize Laureate for his research in virtual water.
Virtual water is an effective education tool and a fun way to look at water consumption. I was surprised to find out that a morning cup of coffee has a virtual water footprint of 37 gallons and a pair of leather shoes, 4,400 gallons. To learn more, visit www.waterfootprint.org

Liquid Assets,PBS Documentary Examines Infrastructure
I noticed this ad for a new PBS Documentary coming out in October while reading the magazine ONTAP. The verbiage below is verbatum from this ad. In my opinion, this is one documentary we should all watch………Liquid Assets tells the story of our aging water systems.
Liquid Assets, a 90-minute documentary, tells the story of essential infrastructure systems: water, wastewater, and stormwater. These systems-some in the ground for more than 100 years-provide a critical public health function and are essential for economic development and growth. Largely out of sight and out of mind, these aging systems have not been maintained, and some estimates suggest that this is the single largest public works endeavor in our nation’s history.
Liquid Assets is slated for release in October 2008. This program will not be shown in our area.
