Overview
ETE Limoeiro serves Álvares Machado, São Paulo, Brazil, treating wastewater for over 200,000 people. The plant operates under Brazil's national water quality regulations.
ETE Limoeiro is a major wastewater treatment facility located in the Bairro Limoeiro area of Álvares Machado, in the state of São Paulo, Brazil. It serves a population of over 208,000 people, placing it in the large agglomeration category under Brazilian regulatory frameworks. The plant is situated inland, approximately 50 km from the coast, and its operations are critical for managing municipal wastewater in the region. Brazilian regulations for large agglomerations typically require at least secondary treatment to meet effluent standards. Its population served indicates a substantial infrastructure footprint. Compliance with federal CONAMA resolutions and state-level environmental agencies ensures that treated effluent meets required quality parameters before discharge. The treated wastewater from ETE Limoeiro 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 provides water for agriculture, industry, and drinking water downstream. Effective treatment at this plant helps protect water quality in the Paraná watershed and contributes to the ecological health of the region.
Environmental context
The plant's discharge flows into tributaries of the Paraná River, which ultimately reaches the Río de la Plata estuary. The Paraná basin supports a rich biodiversity, including migratory fish species and wetlands that are ecologically sensitive. Proper treatment is essential to prevent nutrient loading and contamination that could affect downstream aquatic life and water users.
