ETE SAMARITA is a wastewater treatment plant located in São Vicente, within the Baixada Santista metropolitan region of São Paulo, Brazil. The plant serves a population of approximately 22,844 people, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. As a plant in Brazil, ETE SAMARITA operates under the national regulatory framework established by the National Environmental Council (CONAMA) and the National Water Agency (ANA). Brazilian regulations require secondary treatment for urban wastewater, with more stringent standards for discharges into sensitive water bodies. The plant is situated near the coast, within 50 km of the Atlantic Ocean, and its treated effluent likely discharges into local water bodies that drain into the Santos estuary or directly into the ocean. The Baixada Santista region is ecologically important, supporting mangroves and estuarine habitats that are critical for fish and bird species. Proper treatment is essential to protect these coastal ecosystems from nutrient pollution and pathogens.
Environmental context
ETE SAMARITA discharges into the Baixada Santista watershed, which drains into the Santos estuary and ultimately the Atlantic Ocean. The region features extensive mangrove forests and estuarine environments that serve as nursery grounds for marine life and support migratory birds. Protecting these habitats from untreated or inadequately treated wastewater is critical for maintaining biodiversity and water quality in the coastal zone.
