ETE Porto Fluvial - Wastewater Treatment Plant in Petrolina, Pernambuco, Brazil

ETE Porto Fluvial is a wastewater treatment plant located in the Distrito Industrial area of Petrolina, in the state of Pernambuco, Brazil. The plant serves a population of approximately 7,670 people, classifying it as a small-scale municipal facility. It is situated in the semi-arid region of northeastern Brazil, an area characterized by the São Francisco River basin. As a Brazilian wastewater treatment plant, ETE Porto Fluvial is subject to the national regulatory framework established by the Conselho Nacional do Meio Ambiente (CONAMA) and the Agência Nacional de Águas (ANA). For small agglomerations like this, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids. The treated effluent from ETE Porto Fluvial is discharged into the local environment, which ultimately drains into the São Francisco River, one of Brazil's most important waterways. The São Francisco River flows northward through the semi-arid region and empties into the Atlantic Ocean. The river supports diverse aquatic life and provides water for irrigation, drinking, and hydropower, making the plant's treatment performance critical for downstream water quality.

The plant is located in the São Francisco River basin, a major watercourse in northeastern Brazil that flows into the Atlantic Ocean. The river supports a variety of fish species and is an important migratory corridor. The semi-arid climate means water resources are scarce, and maintaining good effluent quality is essential to protect downstream ecosystems and human uses.
