Bottled Water a Huge Oil Drain?

I did not know this about bottled water:

The Pacific Institute, a California think thank on sustainability issues, contends that producing bottles for US water consumption required the equivalent of more than 17 million barrels of oil in 2006, not including the energy for transportation.

Assuming these numbers are correct then that is quite a bit of oil that is being wasted so that someone can drink something that already comes out of a tap. I already drink tap water in a recycled bottle that I keep in my refrigerator. All you need to do if you are worried about your tap water is buy a Brita water filter. I guess bottled water would be good to store for a natural disaster but any other time it seems like a rip off.
