Mexico City sinks several inches annually.


The city itself drops between 0.2 and 1.3 feet per year! Because Mexico City has one of the world’s largest metropolitan areas, there is an extremely high demand for water.

70% of this water comes from the groundwater beneath the city. But it is being extracted much faster than it can be naturally replaced.

This drastic water deficit has severely weakened the ground upon which the city rests, causing the Mexican capital to sink.
