According to total sales, the U.S. market is the largest bottled water consumer market. In 2018, the U.S. bottled water sales volume amounted to approximately 13.85 billion gallons - the highest volume of bottled water ever sold in the United States. The U.S. market has undergone a major transformation since the early 1990s, when most produced bottled water came from smaller, regional operating companies. Today, the market is highly concentrated with two brands generating more than 1 billion U.S. dollars in sales each.
Many reasons are discussed why U.S. consumers purchase such a large amount of bottled water. First, it is assumed that the convenience of single-packed bottled water plays a major role. Second, bottled water offered in single-serving containers is very appealing to customers and third, it is seen as very healthy zero calorie beverage of choice. Therefore, it is not surprising that the United States' per capita consumption of bottled water reached an all-time high with 42.3 gallons in 2018.
