Starting Aug. 20, San Francisco International Airport will no longer allow restaurants, vendors or vending machines to sell single-use plastic water bottles on airport grounds. KGO-TV reported that travelers who want to take water with them on their flights will have to bring their own bottles, or purchase a refillable aluminum bottle to fill up at an airport fountain.

SFO is making the move to ban plastic water bottles as part of an airport plan to reduce overall landfill waste and energy use over the next two years.

The airport, which is on property owned by the city of San Francisco, also is enacting the ban in order to fall in line with a 2014 edict that bans plastic water bottles being sold on city-owned property.

The ban reportedly only includes plastic water bottles. Bottles of flavored water are exempted from the restriction, and it would seem as if sales of soda in plastic bottles would also be permitted.

Doug Yakel, SFO’s spokesman, didn’t immediately return a request for comment on the ban.
