In a story by the Associated Press that is being picked up by various media outlets, it is being reported that Mexico City lawmakers have recently approved a law that will require all restaurants to install filters to offer free water. Mexico is unfortunately known for its tap water causing stomach troubles, so this has led to the country being the world’s top consumer of bottled water and soda too.

Because of the country’s widespread obesity problem, the city’s health department is backing the efforts to have filters installed in restaurants, and restaurants will have six months to do so. The installed filters could cut down on some of the cost of bottled water to locals. According to the Associated Press, “Mexicans consume 69 gallons (260 liters) of bottled water per capita each year, mostly from 5-gallon (20-liter) jugs delivered by trucks to restaurants and homes.”

It might be an uphill battle for Mexico City to change the public’s perception of its tap water, but it’s encouraging that lawmakers are taking active measures to advocate for tap water.
