Overview
ETE ALTO DO PICUAIA is a secondary wastewater treatment plant in Lauro de Freitas, Bahia, Brazil. Serving about 8,662 people, it discharges treated effluent near the Atlantic coast.
ETE ALTO DO PICUAIA is a municipal wastewater treatment plant located in the Itinga neighborhood of Lauro de Freitas, within the Salvador metropolitan area in Bahia, Brazil. The plant serves a population of approximately 8,662 residents, reflecting its role in managing domestic wastewater for a smaller urban community in the coastal region of northeastern Brazil. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions), secondary treatment is typically required for inland and coastal discharges to protect water quality. The plant's discharge volume is reported at 99.56 (likely in cubic meters per day or similar unit), indicating a moderate flow consistent with its population served. Treated effluent from ETE ALTO DO PICUAIA is discharged into the local watershed, which drains into the Atlantic Ocean via coastal streams and estuaries. The plant's proximity to the coast (within 10 km) means its discharge can influence nearshore marine environments, including mangroves and sandy beaches that support diverse aquatic life. Proper treatment is essential to prevent nutrient enrichment and protect the ecological health of the receiving waters.
Environmental context
The plant discharges into the coastal watershed of Bahia, ultimately reaching the Atlantic Ocean. The region features mangrove ecosystems and estuarine habitats that serve as nurseries for fish and crustaceans. Nutrient and pathogen control from secondary treatment helps maintain water quality in these sensitive coastal areas, which are important for local fisheries and tourism.
