Brazil's biggest city may cut water service to 2 days a week
AP January 28 2015

SAO PAULO (AP) -- The worst drought to hit Brazil's biggest city in decades may leave residents with water service only two days a week.
Sao Paulo water utility company Sabesp says a five days-off, two days-on system would be a last-ditch effort to prevent the collapse of the Cantareira water system. The reservoir is the largest of six that provide water to some 6 million of the 20 million people living in the metropolitan area of Sao Paulo.
