ETE Cafezal Rolândia is a municipal wastewater treatment plant located in Rolândia, within the state of Paraná, Brazil. The facility serves a population of around 14,163 residents, placing it in the small-to-medium agglomeration category. Rolândia is part of the Londrina metropolitan region in southern Brazil, an area characterized by agricultural activity and urban growth. As a Brazilian wastewater treatment plant, ETE Cafezal Rolândia operates under the regulatory framework of the National Environmental Council (CONAMA) and state-level environmental agencies. For agglomerations of this scale, secondary treatment is typically required to meet discharge standards. It is expected to comply with CONAMA Resolution 430/2011, which sets effluent quality standards for wastewater discharges. The treated effluent from ETE Cafezal Rolândia is discharged into local water bodies that drain into the Paraná River basin, one of South America's major river systems. The Paraná River flows southward, eventually reaching the Río de la Plata estuary and the Atlantic Ocean. The plant plays a key role in protecting downstream aquatic ecosystems and water quality in the region.
Environmental context
The plant's discharge enters local streams that are tributaries of the Tibagi River, which flows into the Paranapanema River, a major tributary of the Paraná River. The Paraná River basin supports diverse aquatic life, including migratory fish species and riparian ecosystems. The region's subtropical climate and agricultural land use make effective wastewater treatment critical to prevent nutrient enrichment and protect downstream water quality.
