ETE Curado I Wastewater Treatment Plant, Jaboatão dos Guararapes, Pernambuco

ETE Curado I is a municipal wastewater treatment plant located in the Curado district of Jaboatão dos Guararapes, within the Recife metropolitan area in Pernambuco, Brazil. The plant serves a small population of 691 residents, reflecting its role in a localized community within this densely populated coastal region. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. As a small-scale facility in Brazil, it operates under the national environmental regulations overseen by agencies such as the Conselho Nacional do Meio Ambiente (CONAMA) and the state environmental agency of Pernambuco. These regulations set effluent standards to protect water quality. The treated effluent is discharged into local water bodies that drain toward the Atlantic Ocean, given the plant's proximity to the coast. The receiving waters are part of the broader coastal ecosystem of northeastern Brazil, which supports mangroves, estuaries, and marine biodiversity. Proper treatment helps mitigate nutrient and pathogen loads entering this sensitive environment.

The plant discharges into the coastal watershed of Pernambuco, which ultimately drains into the Atlantic Ocean. This region features estuaries and mangrove ecosystems that provide critical nursery habitats for fish and crustaceans. The secondary treatment reduces organic pollution, but nutrient removal is limited, which could contribute to eutrophication in downstream coastal waters if not managed carefully.
