The use of water supplies and energy are self-evident since car washes are users of such resources. The professional car wash industry has made great strides in reducing its environmental footprint, a trend that will continue to accelerate due to regulation and consumer demand. Many car washes already use water reclamation systems to significantly reduce water usage and a variety of energy usage reduction technologies. These systems may be mandatory where water restrictions are in place. In Europe, Germany is leading the way and has very strict regulations making it illegal to wash your car on the street or in your driveway.
