In July CPFL reduced generation to let water down the dam to supply the public. Too much waste due to too much water. Now it is time to manage better because the mayors discovered business will not settle if there is no water. Not because of low rain fall, but because this center is Sâo Paulo powerhouse. Lots and lots of sugar cane destilleries to make ethanol. (I go there once in a while to visit relatives) They stopped Americana for 15 days by lack of water, wahter there, CPFL says, can spin one turbine. Plant of Salto Grande also lack water. Why the lack of water: “One person needs 2,500m3 of water to live we are supplying 800m3”, says president of Consórcio das Bacias dos Rios Piracicaba, Capivari e Jundiaí (PCJ), José Roberto Fumach (PMDB), mayor of Itatiba. The potential of hidric resources of rivers Piracicaba, Capivari and Jundiaí cannot be used all by the 62 municipalities because a share of the water is reverted back to Cantareira system, to high Tiete e river basin. That is needed to supply São Paulo metwropolitan area and is used to supply 50% of the population there That measn water not coming down, and reverted back, leave munipalities downstream dry. Several of those 62 cities are going to fetch water -by truck- to other basins. Therefore water is being a concern for the future growth of thre region, coimpanies, like soft drinks and beer no longer cans ettle there due to alck of water, the local administartions say. They are working in sustainability. One is control of losses due to bad distribution systems. Losses are estimated to be enough to supply 2,35 million people, euivalent to a city the size of CCampinas. 6,7 thousand liters per second are lost between treatment plant and consumer houses. Just as an example: Jaguariúna os investing in upgrading its system. In 2000, 70% of the treated water never reached the tap. Today this has dropped to 25%. “The investment on upgrading has been already paid back, says the mayor Tarcísio Chiavegatto (PTB). We swapped 60Km of the network and we will swap some 40Km more 2001. In2001 the city captured 250 litros/second, today, after a 25% grow in population we are capturing 150liters/second, says the mayor.cosmo.com.br
