As the bottled water market has developed we've seen many suppliers add things to the water or make claims about their water in order to differentiate their product from the myriad number of others in the market.

Classics like Perrier, although under seige will do well without any changes.

Perception is everything and if you can develop an image like Perrier, or even link your bottled water with a common alcoholic drink then you'll be assured of high levels of sales.

You can add vitamins, minerals, flavors, add micro-nutrients or even supply it as a drink that elevates your IQ by adding specific vitamins and minerals that do this. Of course you could add stamina-improving nutrients for hikers and that type or supply a specific water that caters to the gym crowd and has nutrients specific to them.

There is no specific kid's bottled water drink. I don't think they are being marketed to yet so there may be opportunities there.

No one has thought of supplying a bottle split in two parts with two flavors available. Or even a bottle with a flavor supplement. How about a hip-flask sized bottle? - Would people buy the water to get the bottle to re-use again and again for their alcohol? Is there a doggy bottle of water with good doggy things in it?

How about an alcohol flavored water but no alcohol? Is it possible? How about introducing exotic waters like Antarctic, Ice-berg, Arctic, Mt. St. Helens, Everest where they are really obtained from those locations...

I know, you are thinking about the cost to obtain the water from those exotic locations.

How about exotic waters from aquifers that are millions of years old? Could that be a good seller? Could water obtained from the same aquifers that the ancient Romans used be a good seller?

I suppose the really best way is to establish a brand name, get your water on the shelves of convenience stores right next to the best selling brands so that your (slightly cheaper) water is preferred over the big brand water.

Farmers who have high grade aquifers under their land do very well. Maybe it's best to be such a farmer than a water marketer.

Finally... what's the next step from bottled water?
