Estimativa do volume de água pluvial que pode ser reutilizada na suinocultura: um estudo de caso

摘要

The West of Paraná has risen in the context of national agribusiness, where swine production is an increasing and highly important activity. As a result of this activity, there has been an extensive use of natural resources, resulting in environmental impacts mainly due to the high demand for water, which is used both for consumption and for cleaning the stalls. Based on this context, this study aimed to estimate the volume of rainwater that can be reused for the cleaning of installations. The study was carried out in a covered building for raising pigs measuring 1,200 m2, located in the district of Iguipor?, in Marechal Candido Rondon (Paraná, Brazil). The volume of water was estimated through data related to average precipitation, covering area of the building and sizing calculations of the volume of the cisterns needed for implementation in the property according to ABNT standards (NBR 15527). The results showed that the implementation of the system could represent savings of approximately 77,65% of the water used for cleaning. This demonstrates that rainwater collection decreases the impact on the use of treated water and contributes to the conservation of this important natural resource.
