CAPTAÇÃO DE ÁGUA PLUVIAL PARA HIGIENIZAÇÃO DAS INSTALAÇÕES EM UMA GRANJA DE SUINOCULTURA

Abstract

Pig farming as well as other agricultural activities depends on environmental products and services for their sustainability, such as availability of good quality water and effluent and waste dilution capacity, and one of the environmental concerns of this activity is the excessive consumption of drinking water. both in the consumption of animals and the constant hygiene of the facilities aiming at a better welfare for the animals and a decrease in the occurrence of sanitary diseases. The work was conducted at the Rural Producer Alceu Falchetti Property in Rio Verde-GO, where a rainwater catchment system was built. In this system, water is collected from the roofs of the sheds and transported by gravity through asbestos roof tiles to a cement box where it passes through a filtering screen for removal of coarse materials, then is conveyed to a cistern and then pumped to a raised box and carried by gravity by the PVC pipe until the use in the sanitation of the installations. Physicochemical (pH, turbidity, alkalinity, conductivity and total dissolved solids) and bacteriological (total coliforms and Escherichia coli) parameters of rainwater were evaluated. The data obtained were compared with the parameters established NBR 15527/2007 for non-potable uses, and with the standard established by CONAMA 357/05 for the classification of water class. Sample collection and analysis were performed in February 2019 and in general, it can be concluded that the water analyzed is of good quality and meets the standards established by NBR 15527/07. The analyzed rainwater is classified as class I and II, in relation to the analyzed parameters. Regarding biological parameters, the water samples did not show total coliforms and Escherichia Coli, indicating their potential for use in public supply or animal desedentation, after undergoing simple or conventional treatment.
