  • A poor neighborhood in Rio de Janeiro, Brazil, has independently built a system to process waste in an effort to make the area healthier.
  • 2
  • Supporters say the system could serve as a model for small communities across Brazil.
  • 3
  • The Enchanted Valley community just outside Rio de Janeiro's Tijuca Forest National Park recently built its own waste treatment system.
  • 4
  • The Enchanted Valley is one of Rio de Janeiro's poorest neighborhoods.
  • 5
  • The Brazilian word for such a neighborhood is favela.
  • 6
  • The area did not have electricity until the late 1900s.
  • 7
  • And Enchanted Valley had never been connected to the city's sewage network.
  • 8
  • Waste was polluting the local environment and putting the health of those who live in Enchanted Valley at risk.
  • 9
  • As a result, the community set out to solve the problem on its own.
  • 10
  • It built a local waste treatment system called a biodigester.
  • 11
  • An artificial wetland was built to process the sewage created by all of the area's 40 families.
  • 12
  • Theresa Williamson heads Catalytic Communities, a nonprofit group that supports poor communities.
  • 13
  • She said the system started full operations in June, and it is the first independently built biosystem for a favela in Brazil.
  • 14
  • Official data says 45 percent of Brazilians' sewage is not collected.
  • 15
  • The Enchanted Valley project took years to complete.
  • 16
  • Otávio Barros is president of a group representing the local people.
  • 17
  • He got the idea to build a sewage system when he brought a group of tourists to a nearby waterfall in 2007.
  • 18
  • They wanted to get in the water, but he told them they could not.
  • 19
  • He knew all of the community's sewage flowed down the waterfall.
  • 20
  • Then, Barros started to look for support to build a waste treatment system.
  • 21
  • He found allies among researchers of Pontifical Catholic University of Rio de Janeiro.
  • 22
  • He had been working there as an administrative assistant.
  • 23
  • He told the Associated Press, "It was harder back then to make people aware, show that everyone would benefit."
  • 24
  • He and his allies secured money from the State of Rio de Janeiro.
  • 25
  • That research support led to completion of the first step in 2015.
  • 26
  • The effort also received financial support from German and Brazilian nonprofit groups Viva Con Agua and Instituto Clima e Sociedade to connect every home.
  • 27
  • And it received additional money from Catalytic Communities.
  • 28
  • Barros worked with five other local people from the neighborhood for months, including three weeks of breaking through rock to set down pipes.
  • 29
  • The pipes lead to the biodigester.
  • 30
  • Sewage is processed there by microorganisms that do not require oxygen.
  • 31
  • Remaining fluids then flow underneath the artificial wetlands, getting cleansed by fertilizing the plants above.
  • 32
  • The full price of the system was about $42,300.
  • 33
  • That is one fourth of what it would have cost to place pipes through the forest to the existing sewage network at sea level, said Leonardo Adler.
  • 34
  • He is founding partner of Taboa Engenharia, which supervised the technical part of the work.
  • 35
  • The federal government has a plan to improve sewage treatment throughout Brazil.
  • 36
  • It plans to do that through private concessions of large areas in cities.
  • 37
  • But that plan does not help small, distant communities like Enchanted Valley.
  • 38
  • Barros said he is very happy because it was a very difficult step to bring in partners and "involve the community to capture the sewage and return it to the environment clean."
  • 39
  • He said, "It's part of a dream becoming reality," and added, "We have others for the Valley."
