ETE Corumbataí do Sul - Secondary Wastewater Treatment Plant in Corumbataí do Sul, Paraná

ETE Corumbataí do Sul is a municipal wastewater treatment plant located in Corumbataí do Sul, a small town in the state of Paraná, Brazil. The plant serves a population of 1,161 residents, reflecting its role in a small agglomeration. It is situated in the Região Geográfica Imediata de Campo Mourão, within the broader Região Geográfica Intermediária de Maringá. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for communities of this size. Brazilian environmental legislation, including CONAMA resolutions and state-level norms, mandates adequate treatment to protect water quality. The plant's daily discharge volume is 108.00 cubic meters, indicating a modest operational scale consistent with the local population. The treated effluent is discharged into a local watercourse, which ultimately drains into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and is important for regional water supply and agriculture. The plant's secondary treatment helps reduce organic load and pollutants, contributing to the protection of downstream water quality and ecological health.

The plant discharges into a tributary of the Paraná River basin, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. This basin supports diverse aquatic life, including fish species important for local fisheries. The secondary treatment process helps mitigate nutrient and organic pollution, safeguarding the ecological integrity of downstream waters.
