ETE Alto Alegre SP - Secondary Wastewater Treatment Plant in Alto Alegre, São Paulo

ETE Alto Alegre SP is a municipal wastewater treatment plant located in Alto Alegre, within the São Paulo state of Brazil. The facility serves a population of 2,920 residents, reflecting its role in managing domestic wastewater for this small community in the southeastern region of the country. The plant employs secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a daily discharge volume of 343.91 m³, the plant operates under Brazil's national environmental regulations, which require adequate treatment for water body protection. For small agglomerations like Alto Alegre, secondary treatment is typically sufficient to meet effluent standards. The treated effluent is discharged into local watercourses that drain into the Tietê River basin, a major watershed in São Paulo state. The Tietê River flows westward across the state and eventually joins the Paraná River system, which empties into the Río de la Plata estuary. This downstream connection underscores the plant's role in protecting regional water quality and aquatic ecosystems.

The plant's discharge enters local streams within the Tietê River basin, which flows into the Paraná River and ultimately the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The secondary treatment helps reduce organic pollution, safeguarding downstream habitats and water quality for communities and ecosystems.
