In what was once lake Texcoco now stands the 3rd most populous city in the world. "Ciudad de los Palacios" ("City of Palaces"), or as we know it Mexico City, is home to more then 20 million (2003) people and serves as the governing capital of Mexico. Like many other metropolis D.F. (as known by the Mexican people) post enormous water sanitation and distribution problems. Ironically enough, the waters once known as lake Texcoco, in which the city lays its foundation on causes as many problems pertaining to this matter as it solves.
Much like Seattle WA, Mexico city is sinking into the ground. Unlike Seattle this is mostly from poor planning and over use of the cities under lying ground water, not sandy; unstable

But how do you combat this crisis? One solution, installing low-flow toilets could cut usage by 70 percent. (CIP) New York city in the mid 90’s was facing a similar water shortage. Facing a choice of a billion dollar pumping station or low-flow toilets, NY opted for the low-flows. 1.33 million low-flow toilets later, water consumption per day drop 70 percent over an eight-year span (91-99), with 70-90 million gallons saved a day!
A solution currently being employed is to fix leaks in the cities out dated water pipes. Anywhere from 27-40 percent of the cities water is lost through leaks, an estimated 1100 gallons could be saved a second if these leak were. Other ideas currently in use or suggested include: Collecting rainfall, Desalination, and drip irrigation. My favorite, drip irrigation would not only save 30-70 percent compared with flood irrigation, but has been shown to increase crop yield 20-90 percent, talk about killing two birds with one stone.
But really when it comes down to it the easiest and most logical way to cut the cities water demand of 7,750 gallons per second would be to teach people water conservation methods, recycle water more effectively, and/or just stop polluting the current sources. Still it’s easier said then done without the proper funding this will never happen. While were on the money subject let me throw just one more fun statistic at you, some 40 percent of water users either never receive water bills or simply refuse to pay them.
