ETE VILA ARRAES Wastewater Treatment Plant, Recife, Pernambuco

ETE VILA ARRAES is a municipal wastewater treatment plant located in the Vila Arraes neighborhood of Recife, Pernambuco, Brazil. The plant serves a population of 2,438 residents in this urban area of the Recife metropolitan region. As a secondary treatment facility, it provides biological treatment to remove organic matter and suspended solids from the wastewater. The plant operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. The facility is classified as a small-scale treatment plant. The regulatory framework in Brazil, including CONAMA resolutions and state-level permits, governs effluent quality standards to protect water resources. The treated effluent is discharged into the local drainage system, which ultimately flows into the Atlantic Ocean via the Capibaribe River and the Recife estuary. The coastal location means the discharge can affect nearby beaches and mangrove ecosystems. Proper treatment is essential to prevent nutrient pollution and protect marine biodiversity in this densely populated coastal region.

The plant discharges into the Capibaribe River basin, which flows through Recife and empties into the Atlantic Ocean. The receiving waters include estuarine and coastal environments that support diverse aquatic life, including mangroves and fish species. The proximity to the coast (within 10 km) means the effluent can influence nearshore water quality and marine habitats, making effective treatment critical for ecological health.
