In 2010 UK consumers each drank around 33 litres of purchased bottled water – whether it was fizzy, mineral or just ‘purified’ tap water under a different name. The market for bottled water in the UK alone has grown to over 2 billion litres a year and is worth around £1.44 billion. Worldwide bottled water consumption is estimated at over 155 billion litres a year, enough water to fill 62,000 Olympic swimming pools.
