Hmm. Napkin math assuming its 40 gallons of sugared soda at a reasonable 20g per 8oz serving is 640 servings, 12800g of sugar, 51200 calories, or 14.6 lbs of empty nutrients on average a year if it all got replaced by calorie-free sweetener.

How much is 40 gallons? 426 12 oz cans of soda, 35.5 dozen cans, or 256 20oz bottles of soda.

I wonder if the bad quality of the majority of tap water has an effect on soda consumption. How much less soda would we drink if every residence had on-site water filtration?
