ETE GOIANA Wastewater Treatment Plant - Goiana, Pernambuco, Brazil

ETE GOIANA is a municipal wastewater treatment plant located in Goiana, Pernambuco, Brazil, along Rodovia Governador Mario Covas. The plant serves a small population of approximately 1,016 residents, reflecting its role in a smaller urban community within the Recife metropolitan region. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated under national environmental standards (CONAMA resolutions) and state-level permits. For a plant of this size, secondary treatment meets typical requirements for inland or coastal discharge. The treated effluent is discharged into local water bodies that drain toward the Atlantic Ocean, given the plant's proximity to the coast (within 10 km). The receiving environment supports estuarine and marine ecosystems, and proper treatment helps protect water quality in the coastal zone of Pernambuco.

The plant discharges into the coastal watershed of Pernambuco, with the treated effluent eventually reaching the Atlantic Ocean via local rivers and estuaries. This coastal region supports mangroves, seagrass beds, and diverse marine life. Effective secondary treatment reduces organic load and nutrients, mitigating eutrophication risks in the sensitive coastal environment.
