ETE VILA CONCEICAO - Secondary Wastewater Treatment in Porto Amazonas, Paraná

ETE VILA CONCEICAO is a wastewater treatment plant located in Porto Amazonas, a municipality in the state of Paraná, Brazil. The plant serves a small population of 312 residents, reflecting its role in a rural or small-town setting. It operates under Brazil's national environmental regulations, which mandate secondary treatment for discharges into freshwater bodies. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a daily discharge volume of 86.40 m³, the facility is sized for a small community. Brazilian regulations, such as CONAMA Resolution 430/2011, set effluent quality standards for such plants, ensuring protection of receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Iguaçu River basin, a major watershed in southern Brazil. The Iguaçu River flows into the Paraná River, which forms part of the La Plata Basin, one of the largest river systems in South America. Proper treatment helps protect downstream aquatic ecosystems and water quality for communities relying on these rivers.

The plant discharges into local streams that feed the Iguaçu River basin, which flows into the Paraná River and eventually the Río de la Plata estuary. This watershed supports diverse aquatic life and provides water for agriculture and urban areas. Secondary treatment reduces organic pollution, helping maintain ecological balance in these downstream waters.
