In a change of policy, FIFA will now allow fans to bring their own water bottles to some stadiums during the World Cup, including Reliant Stadium, called "Houston Stadium" during the tournament.

FIFA's decision adjusted a policy that had barred spectators from bringing refillable water bottles into the tournament’s 16 stadiums across North America, including some with limited or no shade from the sun.

FIFA in a social media post said fans will be permitted to bring one, soft, plastic, 20-ounce, factory-sealed, disposable water bottle into any match taking place in the United States or Canada.

In a video released by FIFA, Chief Operating Officer Heimo Schirgi said fans will still not be permitted to bring in hard sided, reusable water bottles “due to safety and security reasons.”

FIFA stated, “for the avoidance of doubt, reusable water bottles may not be brought into the stadium.”

FIFA’s stadium rules had stated that fans could bring in a transparent, reusable bottle up to one liter, or 33.8 ounces capacity. On Thursday, June 4, the “Stadium Code of Conduct” update was criticized by an English fan group, which argued FIFA had given assurances on carrying empty plastic bottles to fill with freely available water at a tournament where heat and extreme weather are expected to be a factor.

Seven FIFA World Cup matches will be played in Houston. AT&T Stadium in Arlington. They includes Germany vs. Curaçao (June 14), Portugal vs. Congo DR (June 17), Netherlands vs. Sweden (June 20), Portugal vs. Uzbekistan (June 23), and Cabo Verde vs. Saudi Arabia (June 26)

The stadium will also host a Round of 32 match (June 29) and one Round of 16 match (July 4).
