ETE FATIMA DO SUL - Wastewater Treatment Plant in Fátima do Sul, Mato Grosso do Sul, Brazil

ETE FATIMA DO SUL is a municipal wastewater treatment plant located in Fátima do Sul, a city in the state of Mato Grosso do Sul, Brazil. The plant serves a population of approximately 2,050 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment stage required for most municipal wastewater in Brazil. Under Brazilian regulations (CONAMA resolutions and the National Sanitation Plan), secondary treatment is expected for communities of this size to reduce organic load and protect water quality. The plant discharges an average of 241.92 cubic meters per day of treated effluent. The treated effluent is released into local watercourses that drain into the Paraná River basin, one of South America's major river systems. The downstream environment supports diverse aquatic life and is used for agriculture and water supply. Proper treatment at this plant helps prevent nutrient pollution and maintains the ecological health of the receiving waters.

The plant discharges into small streams within the Paraná River basin, which flows into the Río de la Plata estuary. The region's watershed supports agricultural activities and sensitive aquatic habitats. Effective secondary treatment reduces organic and nutrient loads, protecting downstream water quality and biodiversity.
