They already do here in the US. Bought any bottled water at the supermarket recently? -- it's, what, about 3 times the cost of gasoline, never mind crude oil.

I can get distilled water for 49 cents a gallon in plastic containers where I live. Reverse osmosis water is only 15 cents a gallon, if you have your own container. Gasoline costs $1.75 a gallon here. Of course gasoline would be closer to 40 cents a gallon if taxes were subtracted from the cost.
