RAINWATER HARVESTING IN MEXICO CITY: Mayor Claudia Sheinbaum has promised to install 100,000 rainwater harvesting systems on rooftops by the end of her six-year-tenure
Millions of people in Mexico City lack access to running water. According to UN-backed research, Mexico City — along with Cairo, Bangalore, Cape Town, and seven other megalopolises — will run out of water by 2030. The irony is, water in the city abounds. Set on a mile-and-a-half-high basin and surrounded by mountains, the city — which used to be integrated with a system of lakes and rivers — receives more yearly rainfall than London, England. Today, most of the city’s water is collected from underground wells or pumped from hundreds of miles away through inefficient and costly infrastructure.
