Overview
ETE LAGOA DE TRATAMENTO is a secondary treatment plant serving Marechal Deodoro, Alagoas, Brazil. It discharges 483.39 m³/day of treated wastewater near the coast, supporting local sanitation infrastructure.
ETE LAGOA DE TRATAMENTO is a wastewater treatment plant located in the Barro Vermelho area of Marechal Deodoro, in the state of Alagoas, Brazil. The plant serves a population of approximately 5,424 people, making it a small-scale facility within the region's sanitation network. It operates as part of the municipal wastewater system for this coastal municipality in northeastern Brazil. The plant provides secondary treatment, which is the standard biological treatment process required for most urban wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Located less than 10 km from the Atlantic coast, the plant's discharge ultimately flows into coastal waters of the South Atlantic Ocean. The region's aquatic ecosystems include estuaries and mangrove areas that are sensitive to nutrient loading. Proper treatment at this facility helps protect local water quality and marine biodiversity in the vicinity of Maceió and the broader Alagoas coastline.
Environmental context
The plant's treated effluent discharges into a coastal watershed that drains into the Atlantic Ocean near Marechal Deodoro. The receiving environment includes estuarine and mangrove ecosystems that support diverse aquatic life and serve as nursery habitats for fish and crustaceans. Nutrient and pathogen removal through secondary treatment is critical to prevent eutrophication and protect downstream coastal waters, which are important for local fisheries and tourism.
Frequently asked questions
ETE LAGOA DE TRATAMENTO is located in the Barro Vermelho area of Marechal Deodoro, in the state of Alagoas, northeastern Brazil.
The plant serves approximately 5,424 people, making it a small-scale municipal wastewater treatment facility.
The plant discharges treated effluent at an average rate of 483.39 m³ per day. Given its proximity to the coast (less than 10 km), the discharge likely enters a local watercourse that flows into the Atlantic Ocean.
The plant provides secondary treatment, which is the standard biological treatment required for most urban wastewater in Brazil. This process reduces organic matter and suspended solids before discharge.
In Brazil, wastewater treatment is regulated by CONAMA resolutions and state environmental agencies. Secondary treatment is typically mandated for urban areas to meet effluent quality standards. Plants of this scale are subject to discharge permits that specify limits for parameters like BOD and TSS.
