    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.
