ETE BAREQUECABA is an advanced wastewater treatment plant located in the Barequeçaba neighborhood of São Sebastião, a coastal city in São Paulo state, Brazil. The plant serves a small population of 448 residents and discharges approximately 500.69 m³ of treated effluent daily. Its coastal location places it within 10 km of the Atlantic Ocean, making effective treatment essential for marine water quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for sensitive coastal areas in Brazil, where federal and state regulations (such as CONAMA resolutions) require high effluent standards to protect receiving waters. The advanced treatment ensures that the discharged water meets stringent quality criteria before entering the environment. The treated effluent from ETE BAREQUECABA ultimately reaches the Atlantic Ocean via local drainage channels. The coastal waters of São Sebastião support diverse marine life, including mangroves and fish populations, and are important for local tourism and fishing. By providing advanced treatment, the plant helps minimize nutrient loading and pathogen release, safeguarding the ecological health of the adjacent marine ecosystem.
Environmental context
