The United States Mission in Brazil, through the U.S. Agency for International Development (USAID) and in partnership with the Cargill Foundation and the Brazilian Agricultural Research Corporation (Embrapa), celebrates the completion of the implementation of a social technology for sewage treatment in the rural area of Porto Velho, in Rondonia state. Seventeen families from a rural community, which had biodigester toilets installed in their residences, attended a breakfast with all project partners.
The technology used is cheap and, besides treating the domestic sewage, it prevents the contamination of soil and groundwater and generates compost that can be used for organic production.

“We saw an excellent opportunity in this project, because it combines environment conservation with the improvement of people’s lives in the Amazon region, which is part of the scope of environmental programs that the U.S. government supports in Brazil,” said Lisa Kubiske, Deputy Chief of Mission for the United States Embassy in Brazil.
This project is one of a number of joint efforts between the United States and Brazil to strengthen environmental protection and support local development.
How it works
The technology, known as a septic biodigester tank, was developed by Embrapa and works by transporting sewage from home toilets into a cement tank that transforms the material into an organic fertilizer via anaerobic biodigestion.
The first tank was built in March and installed at the residence of Luciano Alves do Prado’s. Five months after its installation, Mr. Prado is already using the compost for his açaí plantation. “The implantation of these tanks was an improvement, mainly because it prevents the pollution of water. This is new for Porto Velho,” said Mr. Prado.
The project was funded by USAID, coordinated by the Cargill Foundation and Cargill Porto Velho, and received technical support from Embrapa. The initiative is an alternative solution to the issue of sanitation in rural areas of the Amazon.
“The success of this project is due to the commitment of everyone involved in the process, particularly beneficiary families, who were willing to acquire new skills and knowledge to take care of their sanitation systems”, said Denise Cantarelli, manager of the Cargill Foundation.
“The septic biodigester tank is a cheap and environmentally friendly basic sanitation system that benefits both the environment and public health. The technology is already used in other regions of Brazil and presents itself as a successful alternative for the treatment of sewage,” explains Wilson Tadeu Lopes da Silva, technician for Embrapa.
