Nenshi in Calgary had the right idea - ban bottled water dispensers from civic buildings. Should be extended to all public institutions, universities, schools etc.

Billions spent on municipal water treatment every year, then have to deal with the material waste and energy usage caused by bottled water - ridiculous.

Wherever Coke and Pepsi  bottle water, they simply use local municipal  water anyways, but I'm sure they run it through a cheese cloth filter first. wink wink.

If the hipster set wants to use Evian spring water in their condos and workplaces, knock yourself out.  But how about we add a non-refundable bottle deposit up to say a buck per bottle
