ETE ASPASIA Wastewater Treatment Plant, Aspásia, São Paulo, Brazil

ETE ASPASIA is a wastewater treatment plant located in Aspásia, a municipality in the state of São Paulo, Brazil. Serving a population of 1,273, the plant is part of the regional sanitation infrastructure in the Região Imediata de Jales, within the broader São José do Rio Preto intermediate region. The facility operates under Brazil's national environmental regulations, which mandate secondary treatment for communities of this scale to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a discharge volume of 179.57 cubic meters, the plant manages the wastewater generated by the local community. The plant's operation aligns with typical requirements for small agglomerations in Brazil, where secondary treatment is the baseline for inland facilities. The treated effluent is discharged into local water bodies that drain into the Paraná River basin, a major hydrological system in South America. This basin supports diverse aquatic ecosystems and is vital for agriculture, industry, and drinking water supplies. By treating wastewater to secondary standards, ETE ASPASIA helps reduce nutrient and pathogen loads, contributing to the health of downstream rivers and reservoirs.

The plant's discharge enters local streams that flow into the Paraná River basin, one of the largest river systems in South America, ultimately reaching the Río de la Plata estuary. This basin supports rich biodiversity, including migratory fish species and riparian forests. The secondary treatment process reduces organic pollution, helping to maintain water quality in a region where agriculture and livestock farming are prevalent.
