ETE Ipiranga Ribeirão do Pinhal - Secondary Wastewater Treatment in Ribeirão do Pinhal, Paraná

ETE Ipiranga Ribeirão do Pinhal is a municipal wastewater treatment plant located in Ribeirão do Pinhal, a city in the state of Paraná, Brazil. The plant serves a population of approximately 6,437 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated under national standards such as CONAMA resolutions, which set effluent quality requirements. For small agglomerations like this, secondary treatment is typically sufficient to meet environmental compliance. The treated effluent is discharged into local water bodies that drain into the Paraná River basin, a major hydrological system in South America. The plant plays a crucial role in protecting downstream water quality and supporting the ecological health of the region's rivers and streams.

The plant discharges into the Paraná River basin, which flows into the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The secondary treatment reduces organic pollution, helping to maintain water quality in downstream ecosystems.
