SAN FRANCISCO – If you’re going to San Francisco, you’d better bring your own bottled water. The city’s Board of Supervisors is considering a ban on plastic water bottle sales on public property, the San Francisco Chronicle reports. If passed, San Francisco would join Concord, Mass., in forbidding sales of bottled water.

The San Francisco ban would encompass sales of plastic water bottles with 21 fluid ounces or less on public property in parks, at concerts, large events and via mobile food trucks. The measure would be rolled out gradually as potable water sources are increased on public property.

“Given our access to incredibly healthy clean and tasty Hetch Hetchy water, which is some of the highest quality municipal tap water in the country, it just doesn’t make sense for us to have this addiction to plastic water bottles,” said David Chiu, president of the Board of Supervisors. Plastic water bottles are “incredibly wasteful and environmentally damaging.”

The ban on plastic bottled water sales would start October 2014 for new leases, which include renewals, and permits for vendors in public parks, including mobile food trucks. Two years later, no one would have license to sell or give out water bottles at events held outdoors on public property. The measure also ensures that city departments continue a policy of not buying bottled water.

The American Beverage Association continues to oppose the ban. “The consumer should have a choice on how they drink their water,” said spokeswoman Kate Krebs. “[Plastic bottles] are not being thrown away. They are being recycled.”

Although the legislation would not impact sales of bottled water from retailers on private property, Chiu said he would like to see a more comprehensive bill in the future. “We thought it’s important for The City to set our own example first to show that this can be done easily, well and in an environmentally conscious way,” he said.
