Análise de viabilidade técnica e econômica do uso de água de chuva em uma indústria metalmecânica na região metropolitana de Curitiba PR

This study aims to verify the possibility of rainwater use in a metal-mechanic industry in the municipality of Sao Jose dos Pinhais, metropolitan region of Curitiba, considering the rainfall and the characteristics of rainwater quality in the region, as well as the needs of this industry. A simulation of the charging for water use and emission of effluents into a nearby stream was also conducted. Results of this evaluation showed that the exploitation of rainwater might be feasible due to the hydrological behavior of the region and the quality of such water, which was verified by laboratory testing. In addition, a simulation was conducted to estimate the possible economy with respect to payment for water collection and effluent emission, as well as to the investment in the proposed reservoir for rainwater storage.
