ETE KELLER II is a wastewater treatment plant located in Mandaguari, within the state of Paraná, Brazil. The facility serves a population of around 11,474 people, placing it in the small to medium agglomeration category for Brazilian sanitation infrastructure. The plant is situated along Rodovia Hermínio Antônio Pennacchi in the Jardim Delgado neighborhood, operating as part of the municipal wastewater system. As a Brazilian treatment plant, ETE KELLER II operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies such as Instituto Água e Terra do Paraná. For agglomerations of this size, secondary treatment is typically required to meet effluent standards. It is expected to comply with CONAMA Resolution 430/2011, which sets discharge standards for wastewater treatment plants across Brazil. The plant discharges treated effluent into local water bodies that ultimately drain into the Paraná River basin, one of the most significant hydrological systems in South America. The Paraná River flows southward, joining the Paraguay and Uruguay rivers to form the Río de la Plata estuary. The surrounding region is characterized by agricultural activity and urban development, making proper wastewater treatment essential for protecting downstream water quality and aquatic ecosystems.
Environmental context
ETE KELLER II discharges into local streams that are part of the Paraná River basin. The Paraná River flows through Brazil, Paraguay, and Argentina before reaching the Río de la Plata estuary. This basin supports diverse aquatic life and is a critical water resource for agriculture, industry, and drinking water. Effective treatment at this plant helps reduce nutrient and pathogen loads, protecting downstream ecosystems and water quality in the broader Paraná watershed.
