ETE NORTE CASCAVEL - Cascavel, Paraná Wastewater Treatment Plant

ETE NORTE CASCAVEL is a municipal wastewater treatment plant located in Cascavel, Paraná, Brazil. Situated along Rodovia José Neves Formighieri in the Canadá district, the facility serves a population of approximately 93,074 residents, classifying it as a medium-to-large agglomeration under Brazilian sanitation frameworks. The plant operates within Brazil's regulatory environment, which mandates compliance with CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997). These regulations set effluent discharge standards and require monitoring of water quality in receiving bodies. For a plant of this scale, secondary treatment is typically expected to meet organic load and pathogen reduction targets. The treated effluent is discharged into local watercourses that drain into the Paraná River basin, one of South America's major river systems. The downstream environment supports diverse aquatic ecosystems and provides water for agricultural and urban uses. Proper treatment at this plant helps protect water quality in the region's streams and rivers.

The plant discharges into tributaries of the Paraná River basin, which flows through southern Brazil, Paraguay, and Argentina before reaching the Río de la Plata estuary. The watershed supports diverse aquatic life, including migratory fish species, and provides water for agriculture and drinking supply. Effective wastewater treatment is critical to prevent nutrient enrichment and maintain ecological balance in this important basin.
