Overview
ETE 5 Distrito Industrial is a secondary treatment plant in Barretos, São Paulo, Brazil, serving approximately 4,545 people with a discharge volume of 864 m³/day.
ETE 5 Distrito Industrial is a wastewater treatment plant located in the industrial district of Barretos, in the state of São Paulo, Brazil. The plant serves a population of around 4,545 people, reflecting its role in managing municipal wastewater for a smaller community within the region. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated by national standards such as CONAMA resolutions, and secondary treatment is typical for facilities of this scale to meet effluent quality requirements for discharge into water bodies. The treated effluent is discharged into local watercourses that drain into the Pardo River basin, part of the larger Paraná River system. This region is ecologically significant, supporting diverse aquatic life and providing water for agricultural and urban uses downstream.
Environmental context
The plant discharges into tributaries of the Pardo River, which flows into the Grande River and ultimately the Paraná River basin. This watershed supports important ecosystems, including riparian forests and wetlands that provide habitat for fish and migratory birds. The region's climate is tropical with wet summers, influencing seasonal flow patterns and the dilution capacity of receiving waters.
