ETE Sao Tome Cianorte is a municipal wastewater treatment plant located in Cianorte, a city in the state of Parana, Brazil. The plant serves a population of approximately 26,562 people, placing it in the medium-agglomeration category under Brazilian wastewater management standards. It is situated in the southern region of Brazil, an area characterized by subtropical climate and significant agricultural activity. Brazil's wastewater treatment framework is governed by national regulations such as CONAMA resolutions and the National Sanitation Plan (PLANSAB). For plants of this scale, secondary treatment is typically required to meet effluent quality standards. It is expected to comply with federal and state environmental standards for municipal wastewater. The plant discharges treated effluent into local water bodies that ultimately drain into the Parana River basin, one of South America's major river systems. The Parana River flows southward through Brazil, Paraguay, and Argentina, eventually reaching the Rio de la Plata estuary. The plant plays a key role in protecting local streams and the broader watershed from untreated sewage, supporting aquatic life and downstream water quality.
Environmental context
The plant's treated effluent enters local waterways within the Parana River basin, which drains into the Parana River and eventually the Rio de la Plata estuary. This watershed supports diverse aquatic ecosystems, including fish species and riparian habitats. The region's subtropical climate and agricultural land use make proper wastewater treatment essential for preventing nutrient pollution and maintaining water quality in downstream environments.
