RESUMEN
The so-called social technologies have been widely used in many places around the world as a viable alternative for low-income populations to gain access to opportunities for employment and income and other aspects related to quality of life, including basic sanitation. This paper conducts a cost-benefit analysis of using a low cost technology for drinking water used in several countries, namely the SODIS system. The study was conducted in riverside communities living in the island area of Belem municipality, located in the Brazilian Amazon. Data were collected through questionnaires answered by families living on three islands: Jutuba, Nova and Urubuoca. The results were positive, considering the cost-benefit analysis of the project, which demonstrates the economic viability of using the SODIS system in the situation investigated.

As chamadas tecnologias sociais vêm sendo largamente usadas em muitos lugares do mundo como alternativa viável para que populações de baixa renda tenham acesso a oportunidades de ocupação e renda e outros aspectos relacionados à qualidade de vida, inclusive o saneamento básico. O presente trabalho realiza uma avaliação custo-benefício do uso de uma tecnologia de baixo custo para abastecimento de água potável utilizada em vários países, o sistema SODIS. O estudo foi realizado em comunidades ribeirinhas que vivem na área insular do município de Belém (PA), localizado na Amazônia brasileira. Os dados foram obtidos por meio de questionários respondidos por famílias moradoras de três ilhas: Jutuba, Nova e Urubuoca. Os resultados mostraram-se positivos, considerando a análise de custo-benefício do projeto, o que comprova a viabilidade econômica do uso do sistema SODIS na situação investigada.
