Captação de água pluvial para a dessedentação animal

Abstract

The growing demands for water for agriculture and urban supply (due to high population growth) and animal watering tend to increase pressure on water resources, leading to changes in the percentage of fresh water existing in the world. Although Brazil has one of the largest freshwater reserves in the world, approximately 12% of these reserves are irregularly distributed within the national territory. Thus, the use of rainwater for non-potable purposes should grow in the coming years. Some regions of Brazil have been experiencing water stress, as long periods of drought have been happening. Rio Grande do Sul has also been facing, in recent years, water stress, resulting from the lack of rain, and increasing demands, both for human supply and for the watering of animals. This demand should grow 24% for 2030, according to ANA, (2017). In this sense, the objective of this work is to build a system for capturing rainwater as an alternative for watering animals (cattle), in order to reduce drinking water and another alternative for access to water for animals. The preferable waters for animal watering are special class waters, but those of class three or four can be used, depending on the degree of contamination, respecting the parameters of Conama Resolution No. 357 of 2005, for class three and the minimum quality parameters for non-potable uses of NBR 15527 of 2019. Thus, a water collection and reservation system was built, taking advantage of an existing structure on the rural property in the Municipality of Joia - RS.
