ETE TRAIRI Wastewater Treatment Plant, Trairi, Ceará, Brazil

ETE TRAIRI is a wastewater treatment plant located in Trairi, a municipality in the state of Ceará, Brazil. The plant serves a population of approximately 5,674 residents, placing it in the small agglomeration category. It is situated in the Northeast Region of Brazil, near the Atlantic coast. As a Brazilian wastewater facility, ETE TRAIRI operates under the national regulatory framework established by the National Environment Council (CONAMA) and state environmental agencies. For small agglomerations like this, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids. The plant's treated effluent is likely discharged into a local watercourse that flows toward the Atlantic Ocean, given its proximity to the coast (within 50 km). The region's coastal ecosystems, including mangroves and estuaries, are sensitive to nutrient pollution, making proper treatment essential for protecting marine biodiversity and water quality.

The plant is located in the coastal zone of Ceará, within the drainage basin that flows into the Atlantic Ocean. The receiving water body is likely a small river or stream that eventually reaches the ocean. The coastal waters off Trairi support diverse marine life, including fish and crustaceans, and are important for local fisheries. Nutrient loading from untreated or inadequately treated wastewater could lead to eutrophication and harm these ecosystems.
