ETE SAPUCAI MIRM - Pouso Alegre Wastewater Treatment Plant, Minas Gerais

ETE SAPUCAI MIRM is a wastewater treatment plant located in Pouso Alegre, in the state of Minas Gerais, Brazil. The plant serves a population equivalent of approximately 112,447, classifying it as a large-scale municipal facility within the region's sanitation infrastructure. As a major treatment plant in southeastern Brazil, it operates under the regulatory framework established by the Brazilian National Environment Council (CONAMA) and state-level environmental agencies. For facilities of this scale, secondary treatment is typically required to meet discharge standards, with potential nutrient removal in sensitive watersheds. The plant discharges treated effluent into local watercourses that drain into the Sapucaí River basin, part of the broader Paraná River system. This river network supports diverse aquatic ecosystems and provides water for downstream communities, making effective treatment essential for regional water quality and public health.

The plant's treated effluent flows into tributaries of the Sapucaí River, which is part of the Paraná River basin. This watershed drains into the Río de la Plata estuary, supporting a variety of freshwater and estuarine habitats. The region's aquatic ecosystems are sensitive to nutrient loading, and the plant's performance is critical to maintaining ecological balance in downstream rivers and reservoirs.
