Mexico City is sinking due to the overexploitation of underground water, with the city sinking around 4 inches every year. This sinking poses a significant challenge for engineers who must reinforce the foundations of buildings to prevent damage. The city's sinking is a result of extracting immense amounts of underground water without recharging the system, leading to material compression. Moreover, Mexico is the world's largest consumer of bottled water per capita, driven by both water shortages and a lack of trust in the water supply's quality. This behavior is evident in the common sight of Mexican individuals refilling giant water cooler bottles at convenience stores, reflecting their regular reliance on bottled water consumption.
Officials say “Day Zero” is imminent in Mexico City. A walk through the city reveals the historical roots of the water crisis, its present-day challenges, and the potential solutions.
