Is water a right or a privilege?

After two days of learning about the Tianjin water system the Environmental Group was left to wonder: should all people (in both rural and urban settings) be provided with access to treated water? From our collective points of view we take water for granted - regardless of where we go in the U.S. we can get water either out of our home faucets or from our local grocer. In the plains of rural Tianjin, however, treated drinking water is hard to come by. With underground reservoirs being the norm this means untreated, unfluoridated water is the primary supply available. If residents want treated, healthier options they have to purchase water coolers and make their own arrangements to get barrels of water. When cleaner water is better for one's health, what measures should and can be taken to make sure that everyone has access to defluoridated H2O?
