The Board of Supervisors voted unanimously Tuesday to ban the sale and distribution of water in plastic bottles of up to 21 ounces on city properties in including parks, plazas and buildings.
Supervisor David Chiu says the goal is to end plastic waste. The ban would begin in phases starting in October and would go into effect on city streets and sidewalks by 2016.
The plan also requires more drinking fountains and refillable bottle stations be built.
The International Bottled Water Association says most people won't carry refillable containers and bottled water bans would encourage consumers to turn to high-calorie sugary drinks.
