Although we don’t see it, millions of gallons of water go into the products we buy, use and throw away. The factories that manufacture everyday materials like paper, plastic, metal and fabric depend on water to make and clean their products. Becoming aware of how we use and reuse products is an important step towards water conservation.
Water is used in the production of many materials and finished products we personally use everyday. Take cars, for example. It takes 75,000 gallons of water to produce one ton of steel. Since the average car contains about 2,150 pounds of steel, that means over 80,000 gallons of water is needed to produce the finished steel for one car. The gasoline that fuels a car also requires water consumption: approximately 1 to 2.5 gallons of water is used in the process of refining a gallon of gasoline.
