Captação de água pluvial para reuso em uma fábrica na cidade de Goiana-PE

Abstract

This study aims to implement a rainwater harvesting system via a roof in a factory located in the municipality of Goiana/PE, evaluating its environmental and economic impacts. Specific objectives include: conceptualizing rainwater reuse and its relevance to sustainability; identifying the construction processes necessary for harvesting; and installing a suitable storage reservoir. The methodology adopted is applied, with a qualitative and quantitative approach, based on a literature review and case study. Technical, environmental, and socioeconomic aspects related to the implementation of the harvesting system were analyzed. The procedure included evaluating the building's roof structure, sizing gutters and downpipes, installing a reservoir for rainwater storage, and proposing a treatment method for non-potable uses. An estimate of the reduction in water consumption from the public supply system and the financial savings resulting from reuse was also carried out. The results indicate that the implementation of the rainwater harvesting system is technically feasible and environmentally beneficial. Significant potential for reducing the demand for potable water in activities such as irrigation was observed, contributing to a decrease in the overload on the public water supply system. Furthermore, it was found that rainwater harvesting helps reduce surface runoff, minimizing the risk of flooding and impacts on urban drainage systems. It is concluded that the implementation of a rainwater harvesting system at the factory in Goiana/PE represents a sustainable and efficient alternative for water resource management, promoting environmental, economic, and social benefits. The adoption of this practice contributes to the preservation of natural resources, reduction of operational costs, and strengthening of actions aimed at sustainability in the urban and industrial context.
