San Francisco officials are set to vote on a bottled water ban this week.
The proposal would outlaw the sale of bottled drinking water on city property starting Oct. 1 for indoor events and in 2016 for outdoor events.
The proposal also calls for more drinking fountains and water bottle refilling stations.
Before the vote on Tuesday, a rally is set to be held on the steps of City Hall, including a blind taste test of San Francisco's tap water versus bottled water brands.
