Overview
ETE Planalto is a secondary wastewater treatment plant serving the city of Planalto in São Paulo, Brazil. It treats wastewater from approximately 3,687 residents and discharges treated effluent into local water bodies.
ETE Planalto is a municipal wastewater treatment plant located in Planalto, within the state of São Paulo, Brazil. The facility serves a population of approximately 3,687 people, classifying it as a small-scale treatment plant in the region. It is situated inland, about 50 kilometers from the coast, and operates under Brazil's national environmental regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Brazil. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is recorded at 586.42 (likely cubic meters per day or similar unit), indicating consistent operation. The treated effluent from ETE Planalto is discharged into local water bodies that eventually drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and is crucial for water supply, agriculture, and hydropower in the region. Proper treatment helps protect downstream water quality and ecological health.
Environmental context
The treated effluent from ETE Planalto enters local streams that flow into the Paraná River basin, which ultimately reaches the Río de la Plata estuary. This basin is ecologically significant, supporting diverse fish species and providing habitat for migratory birds. The region's climate is subtropical, with seasonal rainfall influencing river flows and dilution capacity. Effective wastewater treatment is essential to prevent nutrient enrichment and maintain water quality in this important watershed.
