ETE Bonito Quatigua - Secondary Wastewater Treatment Plant in Quatiguá, Paraná

ETE Bonito Quatigua is a municipal wastewater treatment plant located in Quatiguá, within the state of Paraná, Brazil. The facility serves a small population of approximately 1,780 residents, reflecting its role in a smaller urban agglomeration in the southern region of the country. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. Under Brazil's national environmental regulations, secondary treatment is typically required for urban wastewater before discharge. The plant's discharge volume is recorded at 259.20 cubic meters, indicating its operational scale. The treated effluent is discharged into local water bodies that drain into the Paraná River basin, a major hydrological system in South America. The downstream environment supports diverse aquatic life and is important for regional water resources. The plant's operation helps protect local water quality and contributes to the health of the broader watershed.

The plant discharges into the Paraná River basin, which flows into the Río de la Plata estuary. This basin is ecologically significant, supporting diverse fish species and providing water for agriculture and human consumption. The secondary treatment reduces organic pollution, helping maintain water quality in downstream ecosystems.
