Overview
ETE TOLEDOS 1 is a municipal wastewater treatment plant serving Santa Bárbara d'Oeste, São Paulo, Brazil. It treats wastewater for approximately 75,874 people under Brazil's national water quality regulations.
ETE TOLEDOS 1 is a wastewater treatment plant located in Santa Bárbara d'Oeste, within the state of São Paulo, Brazil. The plant serves a population of approximately 75,874 residents, making it a medium-sized facility in the region's sanitation infrastructure. It operates under Brazil's national environmental framework, which mandates treatment standards for municipal wastewater. Brazil's wastewater treatment regulations require secondary treatment for urban agglomerations of this scale, typically involving biological processes to reduce organic load and pathogens. Plants serving populations over 50,000 are expected to meet effluent quality standards set by the National Environment Council (CONAMA). The plant's capacity and operational details align with typical municipal systems in the state of São Paulo. The treated effluent from ETE TOLEDOS 1 is discharged into local water bodies that drain into the Piracicaba River basin, a key tributary of the Tietê River. The Tietê River flows through São Paulo state and eventually reaches the Paraná River basin, which empties into the Río de la Plata estuary. The plant plays a crucial role in protecting downstream water quality and aquatic ecosystems in this densely populated and industrialized region.
Environmental context
The plant discharges into the Piracicaba River basin, part of the larger Tietê River watershed. The Tietê River flows across São Paulo state and joins the Paraná River, which ultimately drains into the Río de la Plata estuary. This watershed supports diverse aquatic life and is vital for water supply, agriculture, and industry. Effective treatment at ETE TOLEDOS 1 helps reduce nutrient and pathogen loads, protecting downstream ecosystems and human uses.
