ETE Monções Wastewater Treatment Plant, Monções, São Paulo, Brazil

ETE Monções is a municipal wastewater treatment plant located in the town of Monções, within the state of São Paulo, Brazil. The plant serves a population of approximately 1,846 residents, providing secondary treatment to manage domestic wastewater from the community. As part of Brazil's expanding sanitation network, the facility plays a key role in improving public health and environmental quality in this inland region. The plant operates with secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is recorded at 293.30 units, indicating active operation. In Brazil, wastewater treatment plants are regulated under national standards such as CONAMA resolutions, which set effluent quality requirements to protect receiving water bodies. The treated effluent from ETE Monções is discharged into local watercourses that drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and communities downstream. By reducing pollutant loads, the plant helps safeguard water quality in the region's rivers and contributes to the overall health of the Paraná watershed.

The plant's effluent enters local streams that flow into the Tietê River, a major tributary of the Paraná River basin. This basin drains a vast area of southeastern Brazil, supporting rich biodiversity including fish species and riparian vegetation. Downstream, the Paraná River flows into the Río de la Plata estuary, an ecologically productive zone. The plant's secondary treatment helps mitigate nutrient and organic pollution, protecting aquatic life and water quality in this important watershed.
