Captação e armazenamento de águas das chuvas: o caso da Cerâmica “Irmãos Rolim” em São João do Rio do Peixe-PB.

Abstract

Water scarcity is recurrent in many parts of the world, being common in semiarid lands, where rainfall is irregular, evaporation is high, and groundwater is limited. In this research, the main objective was to present a technical and economic analysis on the feasibility of catching and storing rainwater for "Irmãos Rolim" Ceramic Enterprise, located in São João do Rio do Peixe - PB, semiarid Brazil. This ceramic enterprise has an extensive coverage area in a single building, which brings technical difficulties for the design of rainwater catchment systems. The methodology consisted of surveying data about the studied object and proposing a technically adequate solution for the implantation of a system for catching and storing rainwater. In addition, a cost survey was conducted in order to verify the financial compatibility for the installation of the aforementioned project. The results showed that it is technically and economically possible to install a rainwater catchment system that meets the demands of "Irmãos Rolim" Ceramic Enterprise, considering only 25% of the covered area. Hence, the circumstances of the project suggest the need for an investment of R$ 20,639.62, indicating that the return on investment would occur in less than a year, disregarding maintenance and pumping costs.
