Overview
ETE Bom Jardim Rio Largo is a secondary treatment plant in Satuba, Alagoas, Brazil, serving 1,684 people. It discharges 124.35 m³/day of treated wastewater near the coast.
ETE Bom Jardim Rio Largo is a wastewater treatment plant located in Satuba, within the metropolitan region of Maceió, Alagoas, Brazil. The plant serves a small population of 1,684 people, reflecting its role in a smaller community in the northeastern region of the country. The plant provides secondary treatment, which is the standard biological treatment level required for municipal wastewater in Brazil under national regulations. The plant's discharge volume of 124.35 m³/day indicates its operational scale. Brazilian environmental legislation, such as CONAMA resolutions, sets effluent quality standards for secondary treatment plants to protect receiving water bodies. The plant is situated within 10 km of the coast, meaning its treated effluent likely drains into coastal waters or an estuary. This proximity to the Atlantic Ocean makes proper treatment essential to prevent nutrient pollution and protect marine ecosystems, including coral reefs and mangroves common along the Alagoas coast.
Environmental context
The plant discharges into a coastal watershed that ultimately reaches the Atlantic Ocean. The region's aquatic ecosystems include estuaries and mangrove forests that serve as nurseries for fish and crustaceans. Nutrient loading from wastewater can lead to eutrophication in coastal waters, so secondary treatment helps mitigate this risk. The nearby Mundaú Lagoon and its associated wetlands are ecologically sensitive areas that depend on good water quality.
