House filtered carbonated water, would you pay for it?

Food miles is a topic that is fairly new to our mind sets, yet I don't know about you but I am now extremely conscious of where goods that I buy come from. I read labels, ask retailers and shop at farmers markets or (try) and grow my own. Yes, perhaps I am going a bit 'green', or maybe I’m just a bit more aware. I have even had installed - at great expense - a water filter onto the sink at home so that I no longer feel justified buying bottled water because it 'tastes' better.

I have recently read a few interesting bits and pieces about bottled water and the ethics of it, so was inspired to share when I read Terry Durack’s latest blog post on the same topic. He explores the shocking idea of being served free tap water happily in a restaurant and, the idea that I really like, house filtered and carbonated water.
It sounds like a smart way for a restaurateur to back up the locally sourced, ethically produced mantra that is more often coming from their kitchens. I think it sounds like an idea waiting for some smart person with a fancy soda stream (remember those!) to make a killing. The restaurateur is happy as they can still make money from the house filtered water, the diner is happy as they get a great, ethically produced reasonably priced product and the environmentalists are happy with less unnecessary freighting.

I think it is a win-win-win.

Another piece I was reading in Dumbo Feather, was an interview with Didi Lo one of the developers of the marketing marvel Another Bloody Water. He was talking about selling rights to his branding and filling ABW bottles around the world with locally sourced spring water… now we are thinking!

What do you think of the house filtered carbonated water?

More importantly, would you support it, instead of buying the import?
