Overview
ETE MACEIÓ is a municipal wastewater treatment plant serving Maceió, Alagoas, Brazil. It treats wastewater from approximately 55,911 people and is located within 50 km of the coast.
ETE MACEIÓ is a wastewater treatment plant located in the Benedito Bentes neighborhood of Maceió, the capital of Alagoas state in northeastern Brazil. The plant serves a population of approximately 55,911 people, placing it in the medium agglomeration category under Brazilian regulatory frameworks. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and state-level environmental agencies. For plants of this scale, secondary treatment is typically required, with additional nutrient removal in sensitive coastal areas. The plant discharges into the local watershed, which ultimately drains into the Atlantic Ocean near Maceió. The coastal environment supports mangroves, estuaries, and coral reefs, making proper treatment essential to protect marine biodiversity and water quality for tourism and fisheries.
Environmental context
The plant's treated effluent enters the drainage network of the Mundaú Lagoon system, which connects to the Atlantic Ocean via the Maceió coastline. This coastal lagoon ecosystem supports diverse aquatic life, including mangroves and fish species, and is an important migratory corridor for birds. Nutrient loading from untreated or inadequately treated wastewater can lead to eutrophication, harming water quality and local fisheries.
