ETE VERMELHO is a municipal wastewater treatment plant located in Jardim Cidade Verde, Rolândia, within the state of Paraná, Brazil. The facility serves a population of approximately 10,688 people, classifying it as a small to medium agglomeration under Brazilian sanitation standards. It operates under Brazil's national environmental regulations, which mandate secondary treatment for urban wastewater to protect water quality. The plant provides secondary treatment, a biological process that significantly reduces organic matter and suspended solids. Secondary treatment is the standard required by Brazilian law (CONAMA Resolution 430/2011) for most inland discharges. The plant's discharge volume is recorded at 842.40 cubic meters per day, indicating consistent operation. Treated effluent from ETE VERMELHO is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's most significant river systems. The region's subtropical climate and agricultural landscape make proper wastewater treatment essential for protecting downstream ecosystems and water resources used for irrigation and drinking water supply.
Environmental context
The plant discharges into the Paraná River basin, which flows through southern Brazil, Paraguay, and Argentina before reaching the Río de la Plata estuary. This basin supports diverse aquatic life and is critical for regional agriculture and hydropower. Effective secondary treatment helps prevent nutrient pollution and protects downstream water quality in this ecologically sensitive watershed.
