There are certain attributes that make some brands of spring water stand out from all the others. Tibet 5100 is a brand of natural spring water that is sourced at the bottom of the Himalayan Mountains. These mountains accumulate a lot of snow and ice, which over time seeps into the surrounding ground to emerge in natural springs located at the base of the mountain range. The region in Tibet where this mountain range is located is referred to by locals as the roof of the world. This is because it is in a region untouched by pollution, which helps keep the water in a pure and natural state. Tibet 5100 also comes from a sustainable source of water. Due to the natural ecological development of this region the water that falls on the mountains is never in short supply. To help conserve the area's natural resources the water is placed in PET recyclable plastic bottles.
