ETE RIO DAS LONTRAS Wastewater Treatment Plant, Barbosa Ferraz, Paraná

ETE RIO DAS LONTRAS is a municipal wastewater treatment plant located in Barbosa Ferraz, a city in the state of Paraná, Brazil. The plant serves a population of approximately 2,728 people, placing it in the small agglomeration category. It operates under Brazil's national environmental regulations, which require secondary treatment for inland communities of this size to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a daily discharge volume of 345.60 cubic meters, the facility manages the wastewater generated by the local community. The treatment process ensures that effluent meets regulatory standards before release into the environment. The treated effluent is discharged into a local watercourse that flows through the Paraná region, eventually contributing to the Paraná River basin. This basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and human consumption. The plant's operation helps maintain the health of downstream ecosystems and the broader watershed.

The plant discharges into a tributary of the Paraná River basin, which drains into the Paraná River and ultimately reaches the Río de la Plata estuary. The region's aquatic ecosystems support diverse fish species and migratory birds. Proper treatment is essential to prevent nutrient pollution and protect downstream water quality in this agriculturally active area.
