ETE 1 AREIA is a municipal wastewater treatment plant located in Areia, a city in the state of Paraíba, Brazil. The plant serves a population of approximately 3,916 residents, making it a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. In Brazil, wastewater treatment plants are regulated under federal environmental laws (CONAMA resolutions) and state-level permits. For small agglomerations like Areia, secondary treatment is typical and meets the basic requirements for discharge into receiving waters. The treated effluent is discharged into local water bodies that drain into the Atlantic Ocean via the Paraíba do Sul river basin or nearby coastal systems. The plant plays a key role in protecting downstream water quality and public health in the semi-arid region of northeastern Brazil.
Environmental context
The plant discharges into local streams that flow toward the Atlantic coast, contributing to the broader Paraíba do Sul basin. The region's semi-arid climate means water resources are limited, making effective treatment crucial for maintaining aquatic ecosystems and supporting downstream communities. The treated effluent helps reduce nutrient and pathogen loads, protecting sensitive coastal waters.
