ETE LOTEAMENTO RECIFE - Wastewater Treatment Plant in Petrolina, Pernambuco, Brazil

ETE LOTEAMENTO RECIFE is a wastewater treatment facility located in the Loteamento Recife neighborhood of Petrolina, in the state of Pernambuco, Brazil. The plant serves a population of about 9,375 residents, placing it in the small-to-medium agglomeration category. Petrolina is a major city in the semi-arid Sertão region, known for irrigated agriculture and proximity to the São Francisco River. As a Brazilian wastewater treatment plant, ETE LOTEAMENTO RECIFE operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies. For plants serving populations around 10,000, secondary treatment is typically required to meet effluent standards. The plant's treated effluent is expected to discharge into local water bodies that ultimately drain into the São Francisco River, one of Brazil's most important waterways. The São Francisco River flows eastward to the Atlantic Ocean, supporting diverse aquatic ecosystems and providing water for millions of people. The plant's proximity to the coast (within 10 km) suggests its discharge may influence coastal water quality, though Petrolina is actually inland; the coastal proximity indicator may reflect the broader regional context.

The plant is located in the São Francisco River basin, which drains into the Atlantic Ocean through the states of Bahia, Sergipe, and Alagoas. The São Francisco River is a critical water source for the semi-arid Northeast region, supporting agriculture, hydropower, and biodiversity. Downstream ecosystems include the São Francisco River estuary and coastal mangroves, which are ecologically sensitive areas that rely on good water quality. The plant's discharge, if not adequately treated, could impact these downstream environments, particularly given the region's water scarcity and ecological importance.
