ETE Nova Canaã Paulista - Secondary Wastewater Treatment Plant in Nova Canaã Paulista, São Paulo

ETE Nova Canaã Paulista is a municipal wastewater treatment plant located in Nova Canaã Paulista, a small town in the state of São Paulo, Brazil. The plant serves a population of 899 and provides secondary treatment, which is a biological process that removes organic matter and suspended solids. The plant discharges an average of 144.54 cubic meters of treated effluent per day. As a secondary treatment facility, the plant meets the basic standards required for municipal wastewater in Brazil. The country's regulatory framework, including CONAMA resolutions and state-level environmental agencies, sets discharge standards for BOD, COD, and other parameters. For small agglomerations like this, secondary treatment is typically sufficient to protect receiving water quality. The plant is located within 10 km of the coast, indicating that its treated effluent may eventually reach coastal waters. The region's drainage flows towards the Paraná River basin, which is a major waterway in South America. The plant plays a role in protecting local water bodies and the downstream environment from untreated sewage pollution.

The plant's treated effluent likely discharges into a tributary of the Paraná River basin, which flows into the Río de la Plata estuary and ultimately the South Atlantic Ocean. The coastal proximity means that nutrients and pollutants from the plant could affect sensitive coastal ecosystems, including mangroves and estuarine habitats. The region supports diverse aquatic life and is important for migratory fish species.
