Mexico City Keeps Sinking As Its Water Supply Wastes Away

Mexico City during the rainy season is a clogged-up bathtub: Despite the rainfall, Mexico City’s 20 million residents don’t have enough water to drink. The rain will typically run off concrete covered streets into a drainage system built to avoid flooding. Drinking water has to come from an aquifer under the city, and as the water table drops, the city sinks. Water is usually piped in from hundreds of miles to manke only 30 percent of the city’s water needs. Water that was stored for thousands of years is being pumped out without any being put back in. The question at hand is how does the city recycle the water or use it to recharge the aquifer instead of moving it out of the city.

This article didn’t go into depth about recycled water use except that it is needed. After reading, the main solution might be to use the current $2 billion dollar budget on a system that recycles rainwater and makes it potable. Doing this may increase flooding but a short period of flooding in the near future could decrease the chance of having a sunken city in the far future. A part of the reading addresses the inequalities between social class and how wealthier communities consume up to 400 liters of water while the poor can only get 40 or so to drink. Water is a need and if the money is there, Mexico City needs to start prioritizing a system to recycle water.

  1. This is exactly what our lab today was all about. Aquifers… and the next topic is what happens when they are over-pumped. And of course Mexico City has been paved over like so many other cities so that there is no recharge. I would think rain water would be potable- maybe not. Interesting to note the inequities of water. Same thing applies here. Affluent homes with several toilets and big lawns and meat based diets take a bigger share. Great find for an env. science article. I hope your topic has kept you engaged this year. Drinking water is obviously a huge issue- I hope you feel like you’ve learned a lot.

  2. Well, Mexico City is the highest capital in the world so how much of a difference do a few feet make? But in all seriousness, I had no idea this was a problem that they have yet to find a solution for.
