Why Mexico City is having trouble getting water to its 22 million residents

Julia Galiano-Rios:

Once a week, a city truck delivers water piped into an 800-gallon tank outside her home.

This is the reality for hundreds of thousands of residents in a sprawling metropolis running out of water. Residents in this community, one of many like it in the city, tell us they rely on these trucks for their water consumption.

Now, as the situation worsens and the system becomes more and more strained, tensions rise in these communities, as neighbors vie for what little water there is available.

That means every trip for drivers like Cristian Ovando comes with risks, from navigating narrow, bumpy alleyways to violence.
