THE Tietê and Pinheiros Rivers, which cut through this metropolis of 20 million, flow well enough in some parts. But in certain stretches, they ooze. Their waters are best described, perhaps, as ashen gray. Their aroma, reminiscent of rotten eggs, can induce nausea in passers-by.
José Leonídio Rosendo dos Santos has been diving into both rivers for more than 20 years. Hired largely to unclog drainage gates, he scours the murky depths of the Tietê and Pinheiros, which have symbolized São Paulo’s environmental degradation for decades, bringing to the surface a list of items that is eerie and bizarre.
Over the years, his takings (which, as a contractor for public utility companies, he is required to hand over to the authorities) have included a suitcase with $2,000 inside, handguns, knives, stoves and refrigerators, countless automobile tires, and, in another suitcase, the decomposing remains of a woman who had been dismembered.
“I stopped looking for suitcases after that,” said Mr. dos Santos, 48.
He readily admits that jumping into rivers that rank among the world’s most polluted is not for everyone. But for Mr. dos Santos, a surfer who got into diving to pay for his wave-catching habit, his job has brought him an unusual level of notoriety and admiration from Paulistanos, as the residents of this hard-bitten megacity are called.
On the traffic-clogged highways that trace the rivers’ banks, some drivers stop their cars, taking pictures with their smartphones when they see him preparing to dive. Talk-show hosts marvel at his courage. One newspaper here, describing Mr. dos Santos in his futuristic diving garb, compared him to a “Japanese superhero.”
Part of the fascination with Mr. dos Santos has to do with how Paulistanos view their rivers. As the historian Janes Jorge recounts in a book on the city’s largest river, the Tietê (pronounced tchee-uh-TEY), it was adored by city residents as recently as the middle of the last century, when they fished, swam and held rowing competitions in its waters.
Then São Paulo rapidly expanded to become one of the world’s largest cities, its residents moving into high-rise buildings, gated enclaves and sprawling slums. Factories deposited their waste in the rivers. Flourishing districts in São Paulo’s metropolitan area expanded without basic sanitation systems, discharging sewage directly into the Tietê and Pinheiros.
The rivers now persist in Brazil’s popular culture as dystopian objects of derision. Rock bands like Skank composed songs about the seemingly impossible dream of cleaning up the Tietê. Laerte Coutinho, a cartoonist, created an entire strip, “Pirates of the Tietê,” in which marauders set forth from the malodorous river on raiding expeditions across contemporary São Paulo.
MR. DOS SANTOS, soft-spoken and bespectacled, insists that he has never seen any pirates navigating the Tietê or its tributaries. But he has glimpsed other living beings. Herons tiptoe along some riverbanks. He said that capybaras, the world’s largest rodents, roll in the mud along some stretches of the Tietê and Pinheiros. Alligators have been known to emerge from the rivers, weary but resilient.
One of the most astonishing sights of all, Mr. dos Santos said, was a man in São Miguel Paulista, a gritty district on São Paulo’s eastern fringe, who went by the name Pezão and dived into the Tietê without any gear in search of metal to sell to recyclers. “If there’s anyone who deserves recognition, it’s that guy, not me,” Mr. dos Santos said.
Still, he said he held out hope that the stubborn presence of life along São Paulo’s rivers might reflect the latest phase in their existence: the attempts to resurrect them. Since 1992, the authorities have been advancing with a painstakingly slow project to clean up the Tietê and Pinheiros.
Political leaders here contend that the cleanup effort, financed with loans from the Inter-American Development Bank, is going swimmingly. Gov. Geraldo Alckmin even said this year that by 2015, boats could start taking tourists down the Tietê for glimpses of São Paulo’s wonders. (“The problem is removing the smell,” he acknowledged.)
Brazilian scientists point to precedents of restoring vital waterways, as Paris has done with the Seine or London with the Thames, allowing salmon to thrive there decades after they had disappeared.
Cleaning the Tietê and its tributaries, however, offers complications that are in a league of their own, and paramount among them is access to sewage treatment. This deficiency plagues Brazil’s only truly global city, in which hedge funds inhabit hulking postmodern skyscrapers, well-heeled consumers stream into luxury shopping malls and immigrants are as likely to speak Castilian Spanish as Quechua.
At the same time, four million people — about 20 percent of São Paulo’s metropolitan population — still lack basic sanitation, according to Monica Porto, an expert on water reservoir management at the University of São Paulo. One area in metropolitan São Paulo, Guarulhos, with a population of about 1.3 million and home to the city’s international airport, treated almost none of its sewage before 2011.
PROGRESS is slowly being made to hook up more homes to the sewage system. But São Paulo’s hilly geography and its patchwork of squatter settlements, which persist in areas close to the rivers, make this a forbidding task. So the waste of millions, along with some industrial byproducts of dubious origin, still flows into the waterways once treasured by Paulistanos.
