This is scary and is something I expect to see happen again and again in the future, and not just in Mexico City either:

The cutoff in Mexico affects about a quarter of the capital city's residents -- 5 million people. Mexico City instituted a five-month rationing plan in January with the Thursday-Friday cutoff this week deemed necessary to fix a leaky supply system and to ease -- somewhat -- a supply problem that began when the lakes that once flooded the city were drained 40 years ago.

The leaks problem is not small. Half of Mexico City's water supply is lost through lousy infrastructure alone -- primarily through leaking pipes.

The change in weather patterns over the North American continent has taken its toll too, just as it did in Los Angeles.

Mexico's National Water Commission said that the capital city's water supply system is at its lowest level -- less than 50 percent capacity after low rainfall totals last year and the leaky delivery system.
