ETE OURO PRETO is a municipal wastewater treatment plant located in the Jardim Amazonas neighborhood of Petrolina, Pernambuco, Brazil. The plant serves an estimated population of 30,682, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997), which set discharge limits for organic matter, nutrients, and pathogens. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the São Francisco River, one of Brazil's most important watercourses. The São Francisco River flows eastward to the Atlantic Ocean, supporting diverse aquatic ecosystems and providing water for agriculture, industry, and human consumption across multiple states.
Environmental context
The plant discharges into the São Francisco River basin, a major hydrological system in northeastern Brazil. The river supports a rich diversity of fish species and is a critical water source for the semi-arid region. Downstream, the river flows through the Caatinga biome and eventually reaches the Atlantic Ocean near the border of Alagoas and Sergipe states, where its estuary provides important nursery habitats for marine life.
