ETE SENGeS _ ETE I JAGUARICATU Wastewater Treatment Plant, Sengés, Paraná, Brazil

ETE SENGeS _ ETE I JAGUARICATU is a wastewater treatment plant located in Sengés, a municipality in the state of Paraná, Brazil. The plant serves a population of approximately 7,867 residents, classifying it as a small to medium-sized facility within the region's sanitation infrastructure. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids through biological processes. Under Brazilian regulations, such as CONAMA resolutions and the National Sanitation Plan (Plansab), secondary treatment is expected for urban agglomerations to protect water quality. The plant's discharge volume is reported at 879.55 cubic meters per day, indicating consistent operation. The treated effluent is released into local water bodies that drain into the Paraná River basin, a major hydrological system in South America. This basin supports diverse aquatic life and provides water for agriculture, industry, and communities downstream. Proper treatment at this plant helps reduce nutrient and pollutant loads, contributing to the ecological health of the region's rivers and reservoirs.

The plant discharges into tributaries of the Paraná River basin, which flows into the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems, including fish species and riparian habitats. Effective secondary treatment reduces organic pollution and nutrient enrichment, helping to maintain water quality in downstream water bodies that are important for local biodiversity and human use.
