A decade ago, West Europe accounted for nearly four in every ten litres of packaged water sold globally, according to Canadean. By the end of last year, that had shrunk to little more than a fifth. While the global market for packaged water has jumped by 75%, the West European market has managed to creep up by just 4% in the last ten years and 2014's West European sales remain below that of their 2006 high water mark, when much of Europe basked in tropical weather conditions.
