Overview
ETE Gran Ville das Artes is a secondary treatment plant in Lauro de Freitas, Bahia, Brazil. It serves about 11,836 people and discharges 136.04 units of treated wastewater near the coast.
ETE Gran Ville das Artes is a wastewater treatment plant located in the Itinga neighborhood of Lauro de Freitas, within the Metropolitan Region of Salvador, Bahia, Brazil. The plant serves a population of approximately 11,836, classifying it as a small to medium agglomeration under Brazilian wastewater management frameworks. The plant provides secondary treatment, which is the standard level required by Brazilian regulations (CONAMA resolutions) for most urban wastewater before discharge. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is recorded at 136.04 units, indicating consistent operation. Situated within 10 km of the Atlantic coast, the plant's treated effluent likely drains into local watercourses that flow into the Baía de Todos os Santos, a large tropical bay supporting diverse marine life and mangrove ecosystems. The region's coastal environment is sensitive to nutrient inputs, making proper treatment essential for protecting water quality and aquatic habitats.
Environmental context
The plant is located in the coastal zone of Bahia, within the drainage basin of Baía de Todos os Santos, one of Brazil's largest and most ecologically significant bays. The bay supports extensive mangrove forests, seagrass beds, and coral reefs, providing critical nursery habitats for fish and crustaceans. Treated effluent from the plant ultimately reaches this bay, where nutrient and pollutant loads must be carefully managed to prevent eutrophication and protect biodiversity. The region's tropical climate and seasonal rainfall patterns influence runoff and dilution capacity.
