O uso dos sistemas PIMS e MES no monitoramento das vazões de águas subterrâneas e superficiais como estratégia de sustentabilidade hídrica

This study analyzes the use of PIMS (Plant Information Management System) and MES (Manufacturing Execution System) in monitoring the flow rates of groundwater and surface water as a strategy for water sustainability in the industrial sector. The research is based on a case study of the mining company Samarco, using public information disclosed by the company itself, such as sustainability reports and institutional documents. The objective is to understand how the integration of these technologies contributes to more efficient, safe, and environmentally responsible water management. After the Fundão dam collapse in 2015, Samarco intensified the use of automated systems to ensure greater control over its operations, especially regarding the collection, recirculation, and discharge of groundwater and surface water. The PIMS system is responsible for the real-time collection and analysis of process data, while the MES integrates this information into operational execution, enabling immediate corrective actions. The analysis of the company’s data revealed improvements in water performance, such as increased recirculation rates, reduced intake of new water, and improved traceability of flow measurements. It is concluded that the combined use of PIMS and MES is an effective tool to strengthen water sustainability and ensure environmental compliance in the mining context.
