Overview
ETE Parque das Mangueiras is a secondary treatment plant in Camaçari, Bahia, Brazil, serving a small population. It discharges 1.56 million cubic meters of treated wastewater annually.
ETE Parque das Mangueiras is a wastewater treatment plant located in the Mangueiral neighborhood of Camaçari, Bahia, Brazil. It serves a small population of 22 people and operates within the Metropolitan Region of Salvador. The plant is situated in the Northeast Region of Brazil, an area characterized by a tropical climate and coastal ecosystems. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions), secondary treatment is typically required for inland discharges to protect water quality. The plant's discharge volume is 1.56 million cubic meters per year, indicating consistent operation. The treated effluent is discharged into local water bodies that drain into the Atlantic Ocean via the Baía de Todos os Santos, one of Brazil's largest bays. This bay supports diverse marine life, including mangroves and fish species, and is an important ecological and economic resource for the region. The plant's secondary treatment helps reduce nutrient and organic loads, contributing to the protection of downstream aquatic habitats.
Environmental context
The plant's discharge ultimately reaches the Baía de Todos os Santos, a large tropical bay that supports extensive mangrove forests, seagrass beds, and coral reefs. These ecosystems provide critical nursery habitats for fish and crustaceans and buffer against coastal erosion. The bay is also a key area for artisanal fishing and tourism. Secondary treatment reduces organic pollution, helping to maintain water quality in this ecologically sensitive coastal environment.
