Resumo
Este trabalho de conclusão de curso aborda a análise do potencial de reuso da água por empresas localizadas nas proximidades da Estação de Tratamento de Esgoto Sarandi, considerando sua viabilidade econômica e ambiental. Inicialmente, foi realizado um estudo sobre a importância do reuso da água como alternativa sustentável para o uso racional dos recursos hídricos. Foram levantados dados sobre o volume de efluente tratado pela ETE Sarandi e a necessidade de redução do despejo no rio Gravataí, devido à poluição e às restrições ambientais. Identificaram-se diversas empresas que poderiam utilizar água de reuso, considerando sua localização em um raio de 5 km da ETE Sarandi. Mediante cálculos e estimativas, determinou-se a vazão necessária para cada empresa, levando em conta suas atividades e demandas hídricas específicas. Foi constatado que, ao somar as vazões de todas as empresas analisadas, o volume total corresponderia a uma porcentagem mínima do efluente tratado pela ETE Sarandi. Considerando o potencial de comercialização do efluente tratado, foi discutida a viabilidade econômica dessa prática. Dados foram levantados sobre os custos de transporte da água de reuso e o pagamento mensal de água potável. Verificou-se que, ao descontar esses valores, era possível chegar a uma estimativa de custo para a água de reuso, buscando equipará-la ao valor gasto somente com água potável. Este estudo demonstrou o potencial do reuso da água por empresas próximas à ETE Sarandi, evidenciando sua viabilidade econômica e ambiental. Conclui-se que o incentivo a práticas sustentáveis como o reuso da água pode contribuir para a preservação dos recursos hídricos, a redução da poluição e a promoção de uma gestão mais eficiente dos recursos naturais.
This final paper addresses the analysis of the potential for water reuse by companies located near the Sarandi Sewage Treatment Plant, considering its economic and environmental feasibility. Initially, a study was conducted on the importance of water reuse as a sustainable alternative for the rational use of water resources. Data on the volume of effluent treated by the Sarandi WWTP and the need to reduce discharge into the Gravataí River due to pollution and environmental restrictions were surveyed. Several companies that could use reuse water were identified, considering their location within a radius of 5 km from the Sarandi WWTP. Through calculations and estimates, the necessary flow rate for each company was determined, considering their activities and specific water demands. It was found that, by adding up the flows of all the companies analyzed, the total volume would correspond to a minimum percentage of the effluent treated by the Sarandi WWTP. Considering the potential for commercialization of the treated effluent, the economic feasibility of this practice was discussed. Data were collected about the transportation costs of reused water and the monthly payment for drinking water. It was verified that, by discounting these values, it was possible to arrive at a cost estimate for reused water, trying to equate it to the amount spent on potable water alone. This study demonstrated the potential of water reuse by companies near the Sarandi WWTP, showing its economic and environmental feasibility. We conclude that the encouragement of sustainable practices such as water reuse can contribute to the preservation of water resources, reducing pollution and promoting a more efficient management of natural resources.
