maybe several different points down mill avenue and again in tempe beach park, have hydration stations which offer recycled paper cups and chilled water to people walking around. Maybe a partnership with one of the valley's purified water providers would be an option and in exchange have the water station be a billboard of sorts with specials on how people can utilize their purified water services at their own residence.

Yes, people can walk into any business and by law in az have to be served water if thirsty, but people often times feel they shouldn't just go ask for a free glass of water without buying something additional.
