Mexico City cuts off water supplies

At least two million residents of Mexico City are without water after authorities cut off supplies following a record drop in water reserves.The two-day shutdown of a main pipeline began late on Thursday, in time for the Easter holiday weekend, when many residents are out of town.The move is part of a five-month emergency rationing plan announced by Mexican authorities in January.The city's Cutzamala supply system is at 47 per cent capacity, its lowest ever level because of low rainfall in 2008, Conagua, Mexico's national water commission said.
