Mexico City officials have shut down a main pipeline providing fresh water to millions of residents because reserves have fallen to record low levels. The closure, due to last 36 hours, will affect five million people, or a quarter of the city’s population. Unusually low rainfall [in 2008] and major leakage [50% of water never reaches consumers] are blamed for leaving reservoirs less than half full.
[…] This is the third time the capital has faced such a drastic form of water rationing this year [and] it has been deliberately timed to coincide with Easter weekend, when many residents […] leave the city.
