ETE Pedrinhas Paulista - Secondary Wastewater Treatment Plant in Pedrinhas Paulista, São Paulo

ETE Pedrinhas Paulista is a municipal wastewater treatment plant located in Pedrinhas Paulista, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 2,401 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. For small agglomerations in Brazil, secondary treatment is typically required under national regulations, such as CONAMA resolutions, to protect water quality. The plant discharges an average of 355.33 cubic meters of treated wastewater per day. The treated effluent is released into local water bodies that ultimately 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 and urban use downstream. Proper treatment at this plant helps reduce nutrient and pollutant loads, contributing to the ecological health of the region's waterways.

The plant discharges into local streams that are part of the Paraná River basin, which flows into the Rio de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The secondary treatment process reduces organic pollutants, helping to maintain water quality in downstream ecosystems.
