The system, besides serving the demands of nonpotable toilets of the cited buildings also aims to monitor and evaluate the performance of each component of this technology and to verify the feasibility of its application for the region. In general the system meets the goals.

In Santarém, only 45,34% of the population has access to treated water (Instituto Trata Brasil, 2016). In this scenario, some alternatives to water supply need to be evaluated, the rainwater is one of them. Thus, this paper presents a study of the potential for potable water savings in homes in the municipality of Santarém in Pará. For this were applied the methods proposed by Ghisi and Flowers , in which the relationship between rainfall, water demand and roof area for determining the potential of rainwater use in the studied municipality. The results indicate that the potential for potable water savings ranging between 10 and 100% The main conclusion of this research is that rainwater is a viable alternative to add to the conventional water supply. And that with the use of this feature, there would be significant savings in drinking water and consequently the preservation of water resources in the Amazon .

Potential to capture rainwater for supply: The case of the city of Belém (Pará State, Brazil)

Apesar da riqueza em recursos hidricos da regiao Amazonica, a cidade de Belem e grande defi citaria em abastecimento publico de agua. O aproveitamento da agua da chuva tem potencial e pode ser uma alternativa na regiao. Assim, este trabalho tem por objetivo definir o potencial de aproveitamento domestico da agua da chuva na cidade de Belem. O metodo empregado se baseia na identificacao da pluviosidade na cidade, bem como da demanda e das areas de captacao, definidas estatisticamente. As medias mensais da pluviosidade variam de 111 a 450 mm. O consumo e estimado entre 222 a 260 litros/pessoa/dia. As areas de telhados considerados variam de 35 a 550 m2. Os resultados demonstram que o atendimento com agua da chuva poderia ocorrer no minimo para 18% da populacao (cerca de 200 mil pessoas) e no maximo para cerca de 37% da populacao (cerca de 420 mil pessoas). A agua da chuva tem potencial de sanar o deficit de abastecimento da cidade de Belem. Palavras-chave: agua de chuva, abastecimento, Belem, Amazonia.
