ETEC 12 Wastewater Treatment Plant, Jaboatão dos Guararapes, Pernambuco

ETEC 12 is a wastewater treatment plant located in the Piedade neighborhood of Jaboatão dos Guararapes, within the Recife metropolitan area in Pernambuco, Brazil. The plant serves a small population of 107 people and operates with secondary treatment, which is the minimum standard required under Brazilian regulations for most urban wastewater. The plant's treatment process is secondary, typically involving biological treatment to remove organic matter and suspended solids. The plant's discharge volume of 121.82 m³/day indicates a small-scale facility. Brazilian environmental legislation, such as CONAMA resolutions, sets effluent standards for such plants, and operation requires environmental permits from state agencies like CPRH (Agência Estadual de Meio Ambiente) in Pernambuco. The treated effluent is discharged into local water bodies that drain into the Atlantic Ocean, given the plant's proximity to the coast. The region's watershed includes rivers like the Jaboatão River, which flows into the Atlantic near Recife. The coastal environment supports mangroves and estuarine ecosystems that are sensitive to nutrient pollution, making proper treatment essential for protecting marine biodiversity.

The plant discharges into the coastal watershed of Pernambuco, likely via small streams or drainage channels that flow into the Atlantic Ocean near Recife. The receiving environment includes estuarine and mangrove ecosystems that provide critical habitat for fish, crustaceans, and migratory birds. Nutrient loading from untreated or inadequately treated wastewater can lead to eutrophication and harm these sensitive coastal habitats.
