Sao Paulo Facing Water Shutoffs If Sabesp Withdrawals Cut

Sao Paulo residents may be left without water for hours each day if Sabesp, the largest water company in Latin America, accedes to demands from regulators to reduce withdrawals from its biggest reservoir, a former company executive said.

Cantareira, the four-lake complex that supplies half of South America’s biggest metropolis, has been drained of 95 percent of its water capacity amid Brazil’s worst drought in eight decades. The National Water Agency, or ANA, said last week that Sabesp won’t be allowed to use the last of the water unless the state-run utility can prove it has a plan to manage reservoir supplies better.
