ETE Suzano Wastewater Treatment Plant - Suzano, São Paulo, Brazil

ETE Suzano is a municipal wastewater treatment plant located in Suzano, within the Metropolitan Region of São Paulo, Brazil. The plant serves a population of approximately 95,647 people, classifying it as a medium-to-large agglomeration under Brazilian wastewater management frameworks. It is situated in the southeastern region of Brazil, an area characterized by high urbanization and industrial activity. As a plant serving over 50,000 inhabitants, ETE Suzano is expected to meet secondary treatment standards under Brazilian regulations (CONAMA Resolution 430/2011 and state-level norms). The designed capacity is reported as 1. Typical plants in this region employ activated sludge or similar biological processes to meet effluent quality standards. The plant discharges treated effluent into local water bodies that drain into the Tietê River basin, a major tributary of the Paraná River system. The Tietê River flows through the São Paulo metropolitan area and ultimately reaches the Paraná River, which empties into the Río de la Plata estuary. This downstream pathway highlights the plant's role in protecting water quality in a densely populated and ecologically significant watershed.

ETE Suzano discharges into the Tietê River basin, which flows through the São Paulo metropolitan region and joins the Paraná River, eventually reaching the Río de la Plata estuary. The Tietê River is heavily impacted by urbanization and industrial pollution, making the plant's treatment critical for downstream aquatic life and water quality. The region supports diverse freshwater species and provides water supply for millions of people, emphasizing the need for effective nutrient and pathogen removal.
