ETE 6 Alberto Moreira Wastewater Treatment Plant, Barretos, São Paulo

ETE 6 Alberto Moreira is a wastewater treatment plant located in the Alberto Moreira neighborhood of Barretos, in the state of São Paulo, Brazil. The plant serves a small population of 636 residents, reflecting its role in a localized community within the broader Barretos urban area. As part of Brazil's expanding sanitation network, it contributes to improved public health and environmental quality in the region. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. The plant operates under Brazil's national environmental regulations, which require adequate treatment for small agglomerations. The discharge volume of 120.96 m³/day indicates a modest flow consistent with the population served. The treated effluent is discharged into local water bodies that eventually drain into the Rio Grande, a major tributary of the Paraná River basin. This river system supports diverse aquatic life and provides water for agriculture and communities downstream. By treating wastewater, the plant helps protect water quality in the region's sensitive freshwater ecosystems.

The plant's discharge enters local streams that flow into the Rio Grande, part of the Paraná River basin, which ultimately reaches the Río de la Plata estuary. This watershed supports important aquatic habitats and is used for irrigation and drinking water. Secondary treatment reduces organic pollution, safeguarding downstream water quality and ecological balance.
