ETE Coroados - Secondary Wastewater Treatment Plant in Coroados, São Paulo

ETE Coroados is a municipal wastewater treatment plant located in Coroados, São Paulo, Brazil. The plant serves a population of 4,309 and provides secondary treatment, which is appropriate for a community of this size in the region. As a secondary treatment facility, ETE Coroados removes organic matter and suspended solids through biological processes. The plant discharges an average of 604.52 cubic meters of treated wastewater per day. In Brazil, wastewater treatment plants are regulated under federal environmental laws, including CONAMA resolutions, which set discharge standards for treated effluent. The treated effluent from ETE Coroados eventually reaches the Tietê River basin, a major water system in São Paulo state that flows into the Paraná River and ultimately to the Río de la Plata estuary. The plant plays a key role in protecting local water quality and downstream ecosystems.

The plant discharges into the Tietê River basin, which drains a large portion of São Paulo state. The Tietê River flows through urban and agricultural areas before joining the Paraná River, which empties into the Río de la Plata estuary. This watershed supports diverse aquatic life and provides water for irrigation and drinking. The plant's secondary treatment reduces organic pollution, helping to maintain water quality in this ecologically sensitive basin.
