Water crisis looms as the flood-prone city depletes its groundwater.

Mexico City is a place of water paradox, where flooding is a constant risk and water shortages are a constant reality. In the 1300s, the Aztecs built the beginnings of Mexico City on an island surrounded by lakes. When Spanish conquerors came they hastily drained the lakes and constructed a larger city, despite being deluged by flood after flood. Today, flooding remains a risk.
So does groundwater depletion. Mexico City sits on clay lake beds in the mountains, a mile and a half above sea level. As the city’s population grows, Mexico City is forced to drill deeper for water and there is never enough. In some areas shortages are so severe that water is delivered by trucks just once a week. The excessive drilling led to another problem –Mexico City is slowly sinking into the earth, collapsing on itself.
“We line up at 3 in the morning for the pipa [water truck]. We wait for hours to get water that doesn’t last a week, and usually there aren’t enough pipas. Sometimes there is violence. Women sell their spaces in the line. If you’re from the wrong political party, you don’t get water. You have to show your party affiliation, your voting ID.” —Virginia Josefina Ramírez Granillo, a resident of the San Miguel Teotongo neighborhood, in reference to the water scarcity in many of Mexico City’s communities. In a few places, water is not even trucked in, forcing residents to travel long distances by foot to gather water.

On The Radar
Mexico City is thirsty, sinking, and flood-prone, raising countless concerns about future water availability. Climate change could further upset the problem as rainfall becomes more unpredictable and dry spells more likely. Experts forecast that over the next 60 years average temperatures will rise by several degrees and annual rainfall will decrease by 20 percent.
Government officials are well aware of the city’s water crisis, but coordinating and financing sustainable projects has proven difficult. Federal funding for repairs to the city’s water infrastructure was recently slashed to zero. In the meantime, millions of residents wait, hoping for reliable water service that may never come.
