Water Turn on the tap and out it comes – water. We drink it, we wash with it, we swim in it. Pure water is colorless and odorless and has no taste. Yet it has so many sto- ries to tell. 75 percent of the Earth’s surface is covered by water in liquid and frozen forms – 71 percent in the world’s seas and oceans, some three percent as ice and just one percent in lakes and rivers. Indeed, over a period of one hundred years, a water molecule spends on average 98 years in the sea, 20 months in ice, two weeks in rivers and lakes, and less than a week as gas in the atmosphere. However, of all the water on Earth, only 2.5 percent is drinkable freshwater – and just 0.3 percent of this is accessible to humans. At the XXL truck washing facilities at Gebrüder Weiss, the company’s trucks are cleaned using high-pressure systems and special wash brushes. Unlike at car washes, the driver doesn’t generally stay in their cab while the truck is being scrubbed.
