The Vale Encantado neighborhood was based within the nineteenth century by the employees of the espresso plantations, earlier than the area was reforested to develop into the Tijuca forest, one of many largest on the earth by city perimeter.
The nice-grandparents of Otávio Barros, now president of the Residents’ Affiliation and the Vale cooperative, moved to the area exactly to work on the plantations – and subsequent generations have devoted themselves to different actions, corresponding to agriculture and floriculture.
“I’m from the fourth technology. There was additionally a section of granite extraction, which precipitated deforestation. However in 1989 the businesses left. Many individuals who got here to work didn’t adapt and left. settlement. The extra the unique households remained “.
After 150 years, Vale Encantado discovered herself remoted within the forest, not capable of earn a residing by extracting pure sources from the encircling setting.
Immediately, in line with the newest census carried out by the residents’ affiliation, round 100 individuals dwell within the 27 homes of the neighborhood, of which 40 are households.
In 2005, after the go to of the French Jérôme Auriac, president of a sustainable improvement NGO working in Brazil, Barros started to contemplate the concept that Vale Encantado might be vacation spot for sustainable tourism, an exercise that may assist the neighborhood to generate earnings.
“In 2007, after a colleague and I had been already educated as guides, one of many vacationers who visited us requested if he might take a shower within the waterfall. I defined that no, as a result of neighborhood sewage was dumped there. We continued with the tour, however that bothered me. I began on the lookout for a method to enhance the plumbing, though I did not have any technical information, “he says.
The start of the seek for the sewer system
For residents, correctly channeled sewage represented the presence of fewer bugs, rodents, and a decrease danger of illness transmission, in addition to the non-contamination of the area’s springs.
Nevertheless it additionally helped with an issue that threatened them in a different way. In 2006, the Public Prosecutor of the State of Rio filed a public civil motion and a request for an injunction, towards the Municipality of Rio, for the occupation of the areas of Alto da Boa Vista, the place Vale Encantado is situated.
The motion didn’t focus solely on the neighborhood, however positioned it as a menace to environmental safety, which made the president of the residents’ affiliation really feel much more motivated to hunt options.
In 2011, a researcher on the PUC (Pontifical Catholic College) of Rio de Janeiro, the place Otávio Barros labored because the secretary of the college’s arithmetic course, directed him to talk with Leonardo Adler, an environmental well being engineer who has amassed experiences that would assist the neighborhood.
“On the time we solely spoke by way of e mail. I gave some directions, however we by no means met,” says Adler.
However two years later, Vale Encantado obtained a primary donation from a global NGO that may contribute to the sustainability path that residents had been on the lookout for, a biodigester for leftover meals that may be used within the affiliation’s kind of restaurant, which sells typical dishes corresponding to “jacalhau” and “banana navel cake” for vacationers.
Therefore, the restaurant kitchen used the gasoline generated by the biodigester for cooking.
To work on the implementation of the expertise, engineer Leonardo Andler and different volunteers turned a part of the neighborhood’s routine.
Regardless of the progress, the elevated contamination of the setting continued. With difficulties serving many Rio areas, it could be onerous to think about the seller arriving sooner or later with primary sanitation on this small and remoted place. And this has affected the standard of life and native earnings technology.
The development of the biosystem for waste water therapy
However after having extra skilled professionals who knew the fact of the residents, in 2015, the ecological sanitation biosystem of Vale Encantado started to be developed by means of a brand new partnership, this time with a public discover from Faperj (Fundação Carlos Chagas Filho de Amparo à Pesquisa of the State of Rio de Janeiro), a analysis funding company.
The aim was to construct an adequately sized and sized biodigester, sized to deal with the wastewater of all 27 houses in Vale Encantado, however with the preliminary assist, solely 5 houses benefited.
The method of elevating funds to finish the works was gradual and the pandemic attributable to the coronavirus hampered planning, however in 2021, with the assistance of a number of social organizations, the neighborhood managed to acquire the lacking sources to convey in regards to the completion. of the connection system of all the homes to the entire sanitary community.
The ready time additionally served to coach the residents of the neighborhood to do the work on their very own, being remunerated with a portion of the cash raised.
In response to environmental well being engineer Leonardo Andler, the coaching was carried out with the assistance of a civil engineer and a plumber.
Since Might 2022, the sewage has been collected by households and brought to a round-shaped concrete tank, the place it undergoes two pure processes to scrub the water.
“The system degrades natural matter in oxygen-free environments. From this setting, the micro organism that develop digest the natural matter and have biogas as a byproduct of this digestion. Principally, it is the identical factor that occurs in our stomach – digestion. from a liquid half popping out from one facet, one other stable half, which settles on the underside of the biodigester, and subsequently the creation of the gasoline which, on this case, can be utilized for cooking actions “, explains Andler.
Resident Otávio Barros says that, previous to the mission, many houses used a “sink pit,” a type of reservoir subsequent to a properly, to retailer their waste.
“The standard of the water that flowed by means of the homes was horrible and fashioned puddles the place mosquitoes and rodents thrived. Now the water may be very clear. The residents are happy and there was no price. I feel my ancestors would have. proud, “he says.
His dream, he says, is for Vale Encantado to develop into a vacationer spot to generate earnings for probably the most weak households. The next move is to create a guesthouse for guests.
Moreover, Otávio is following a course on sanitary programs, of which Leonardo Adler is likely one of the professors, and is contemplating exploiting the information acquired in recent times to take part in different initiatives corresponding to what has been achieved in his neighborhood.
