Mexico City and its 20 million people get water from many sources, some nearly 100 miles away. The city has announced plans to achieve water self-sufficiency by 2020, a task sure to be a challenge.

The target is ambitious -- to reach self-sufficiency by 2020 -- and the government faces many serious hurdles. The booming megalopolis of 20 million people currently relies on several outside water sources, some of them rivers up to 80 miles away. The water must be pumped uphill over the mountains that surround the Valley of Mexico via a complex and energy-intensive system."
