The metropolis of nearly 22 million people is facing a severe water crisis as a tangle of problems — including geography and leaks — are compounded by climate change.
What is now Mexico City used to be Tenochtitlan. An artist made a rendering of what Tenochtitlan might have looked like before the Spanish arrived. The entire place was a lake, and the city was built in the middle of the lake. It contained canals everywhere, and had causeways connecting the edges of the lake to the city.
I wonder if Mexico City has been effectively slowly “mining” that lake for centuries. I suppose the lake will be fed by precipitation, because the city is in a bowl so any rain that falls there will be collected, but does the amount of rain come anywhere close to matching what they’re using?
As an aside, to me it’s tragic that the main temple of the Aztecs was razed and a Catholic church was plopped down on top of it. Just as tragic is that the Spanish indoctrination process was so successful that only 0.3% of the country has a non-Christian religion. As a result, most Mexicans see the church the Spanish had built not as a grotesque symbol of the destruction of the original city, but as a good and holy place.
Here’s an oddity. The Spanish burned most of the Aztec and Mixtec (and Mayan) books, but an Aztec emperor did the exact same thing to Aztec books about a century earlier!
Spanish drained the lake in multiple steps to build the modern city. The water they are using is ground water, pumped in an aquifer. Mexico city has a network of canals to drain the storm water.
The other issue is the aquifer doesn’t recharge enough due to the urbanization and consumption. One solution is to use the rain water by cleaning it and storing.
They drained the lake, but if I understand how lakes work, the aquifer is connected to the lake bed. So, initially there was so much water in the aquifer that some of that water was above ground in the form of a lake.
One solution is to use the rain water by cleaning it and storing.
Are you saying that right now the rain water doesn’t reach the aquifer? Like, it’s drained outside the city? Or that instead of having it trickle down into the aquifer, they could collect it above ground and make it available more quickly by cleaning and storing it in man-made structures?
If it’s the second, it sounds like not allowing the rain water to reach the aquifer will mean that it drains more quickly.
