Take, for instance, Pepsi’s Aquafina or Coca-Cola’s Dasani bottled water. Both are sold in 20 ounce sizes and can be purchased from vending machines alongside soft drinks — and at the same price. Assuming you can find a $1 machine, that works out to 5 cents an ounce. These two brands are essentially filtered tap water, bottled close to their distribution point. Most municipal water costs less than 1 cent per gallon.

Now consider another widely sold liquid: gasoline. It has to be pumped out of the ground in the form of crude oil, shipped to a refinery (often halfway across the world), and shipped again to your local filling station.

In the U.S., the average price per gallon is hovering around $3. There are 128 ounces in a gallon, which puts the current price of gasoline at a fraction over 2 cents an ounce.

And that’s why there’s no shortage of companies that want to get into the business. In terms of price versus production cost, bottled water puts Big Oil to shame.

In theory, bottled water in the United States falls under the regulatory authority of the Food and Drug Administration. In practice, about 70 percent of bottled water never crosses state lines for sale, making it exempt from FDA oversight.

On the other hand, water systems in the developed world are well-regulated. In the U.S., for instance, municipal water falls under the purview of the Environmental Protection Agency, and is regularly inspected for bacteria and toxic chemicals.
