Mexico is cutting water to Mexico City’s 8 million residents for 3 days to allow repairs to a 200-mile-long system that loses up to 40% of the water it pumps to leaks. When it is turned back on, it could take up to days for it to reach some areas. In response, individuals across the city are storing water however they can to help weather the cutoff, with buckets and other receptacles selling out ahead of the cutoff. Many businesses are shutting down and others are contracting trucks to haul water. While a highly rare occurrence in modern cities, the cutoff demonstrates the economic and social disruption, as well as threats, that occurs in response to infrastructure failures.
