Zusammenfassung: | Currently, rock outcrops have now been used as simple social technologies that seek to capture and store rainwater and, with this, promote human supply. Thus, the objective was to analyze the quality of the water captured in Tanque do Araçá, a water reservoir over a rocky outcrop in the municipality of Esperança-PB, and to identify the social, economic and environmental benefits of using rocky outcrops in the management of water resources. In this way, it was possible to carry out analyzes of the physical-chemical and microbiological parameters of the water, both in the Araçá tank and in the residences of 135 the families that use the outcrop. Therefore, it was observed that, in spite of the physicochemical parameters, the microbiological analyzes indicated that the stored water, both in the Araçá tank and in the households residences, are contaminated by fecal thermotolerant coliforms, which forces the families to treat such water with the addition of chlorine. However, studies have also pointed out that the storage of rainwater in rocky outcrops has brought many socioeconomic and environmental benefits such as: management of water resources; water safety; reduction of costs with the purchase of water; in addition to meeting the water needs of countless families who coexist with the scarcity of water
Atualmente, tem-se utilizado os afloramentos rochosos como tecnologias sociais simples que buscam captar e armazenar a água das chuvas e, com isso, promover o abastecimento humano. Assim, objetivou-se analisar a qualidade da água captada no Tanque do Araçá, reservatório de água sobre um afloramento rochoso no município de Esperança-PB, e identificar os benefícios sociais, econômicos e ambientais do uso de afloramentos rochosos na gestão dos recursos hídricos. Para tanto, foram realizados estudos qualiquantitativos, utilizando análises loboratoriais de parâmetros físico-químicos e microbiológicos da água, tanto no Tanque do Araçá quanto nas residências das famílias que utilizam a água do referido afloramento. Com isso, observou-se que: apesar dos parâmetros físico-químicos atenderem à legislação vigente, as análises microbiológicas indicaram que a água armazenada, tanto no Tanque do Araçá, quanto nas residências das famílias, apresentam-se contaminadas por coliformes termotolerantes de origem fecal, o que obriga as famílias a tratarem tal água com a adição de cloro. Todavia, os estudos apontaram, ainda, que o uso dos afloramentos trouxe muitos benefícios socio |
