ETE RUA DO RIO Wastewater Treatment Plant, Recife, Pernambuco

ETE RUA DO RIO is a municipal wastewater treatment plant located in the Jiquiá neighborhood of Recife, the capital of Pernambuco state in northeastern Brazil. The plant serves a population of approximately 6,600 residents, contributing to the sanitation infrastructure of the Recife metropolitan region, one of the largest urban agglomerations in Brazil's Northeast Region. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for urban wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is around 785 cubic meters per day, reflecting its scale for a small community. The treated effluent is discharged into local water bodies that ultimately drain into the Atlantic Ocean, given Recife's coastal location. The receiving waters are part of the Capibaribe River basin, which flows through Recife and into the Atlantic. The coastal and estuarine environments near Recife support diverse aquatic life and are important for local fisheries and mangroves, making proper wastewater treatment critical for ecological health.

The plant discharges into the Capibaribe River basin, which flows through Recife and empties into the Atlantic Ocean. The coastal zone includes mangrove ecosystems and estuarine habitats that support fish, crustaceans, and migratory birds. Proper treatment helps reduce nutrient loading and pathogen inputs that could otherwise impact these sensitive coastal waters and the marine environment.
