Socrates SUMMARY ======= Brazil’s major and medium size metropolitan areas face increasing problems of water pollution. Coastal cities such as Rio de Janeiro and Recife suffer effects of upstream residential and industrial sewage contaminating feeder rivers, lakes, and the ocean. In 2000, only 35% of collected wastewater received any treatment.For example, the Tietê River, which runs through the São Paulo metropolitan area (17 million inhabitants), has returned to its 1990 pollution levels. Despite the support from the IDB, the World Bank and Caixa Econômica Federal in a US$400 million cleanup effort, the level of dissolved oxygen has returned to the critical level of 1990 at 9 mg per liter due to increased levels of unregulated sewerage, phosphorus, and ammonia nitrogen discharged into the river. As of 2007, the state water company Sabesp projects that a minimum of R$3 billion (US$1.7bn) would be necessary to clean up the river.
