ETE RIOZINHO IRATI - Wastewater Treatment Plant in Irati, Paraná, Brazil

ETE RIOZINHO IRATI is a wastewater treatment plant located in Irati, a city in the state of Paraná, Brazil. The plant serves a population of approximately 1,575 residents, classifying it as a small-scale municipal facility. It operates under Brazil's national environmental regulations, which mandate secondary treatment for urban wastewater to protect water quality. The plant employs secondary treatment processes, which typically involve biological degradation of organic matter followed by sedimentation. This level of treatment is appropriate for the small population served and helps reduce biochemical oxygen demand (BOD) and suspended solids before discharge. The plant's discharge volume is 259.20 cubic meters per day, indicating consistent operation. The treated effluent is released into local watercourses that drain into the Paraná River basin, eventually reaching the Río de la Plata estuary. By treating wastewater, the plant protects downstream aquatic ecosystems and supports the health of the Paraná River system, which is vital for biodiversity and human use in the region.

The plant discharges into small streams that flow into the Paraná River basin, one of South America's major river systems. The Paraná River ultimately drains into the Río de la Plata estuary, supporting diverse aquatic life and providing water for agriculture and urban centers. The region's subtropical climate and agricultural land use make proper wastewater treatment essential to prevent nutrient pollution and protect downstream ecosystems.
