Abstract
One of the fastest growing industrial cities in the world, São Paulo, Brazil, is located in a region with scarce water resources. Supplying adequate water to the greater São Paulo metropolitan area is a monumental task. At the present time, 1,070 mgd (47 m3/s) of water is supplied to 15 million people in the area, but it is not enough. An additional 450 mgd (20 m3/s) will be needed by the turn of the century. To meet this challenge, Companhia de Saneamento Basico do Estado de São Paulo (SABESP) has developed a new water supply system, the Alto Tiete system, to cover the eastern part of the metropolitan area, together with a 340‐mgd‐(15‐m3/s‐) capacity state‐of‐the‐art water treatment plant, which is now under construction. This article discusses the project and the highlights of the treatment plant design.
