Overview
ETE APOLO is a wastewater treatment plant serving Monjolos in São Gonçalo, Rio de Janeiro, Brazil. It serves a population of approximately 25,972 and is located within 50 km of the coast.
ETE APOLO is a wastewater treatment plant located in the Monjolos district of São Gonçalo, within the Rio de Janeiro metropolitan area, Brazil. The plant serves a population of about 25,972, placing it in the medium agglomeration category under Brazilian regulatory frameworks. It is situated in the Southeast region, a densely populated and industrialized area. As a plant serving a medium-sized population, ETE APOLO is expected to comply with Brazilian national standards for wastewater treatment, which typically require secondary treatment or higher for such agglomerations. The plant operates under the regulatory oversight of environmental agencies in Rio de Janeiro state. The plant's treated effluent likely discharges into local water bodies that drain into Guanabara Bay, a large coastal bay in Rio de Janeiro. Guanabara Bay is an ecologically significant estuary that supports diverse aquatic life and is surrounded by urban and industrial areas. The bay ultimately connects to the Atlantic Ocean, making the plant's performance important for coastal water quality.
Environmental context
The plant is located within the watershed of Guanabara Bay, a large estuarine system in Rio de Janeiro state. The bay receives freshwater from several rivers and channels, and its waters mix with the Atlantic Ocean. Guanabara Bay supports mangrove forests, fish populations, and migratory birds, but faces pressures from urbanization and industrial activities. Proper wastewater treatment at plants like ETE APOLO is critical to reducing nutrient and pollutant loads that can cause eutrophication and harm aquatic ecosystems.
Frequently asked questions
ETE APOLO is located in the Monjolos district of São Gonçalo, in the state of Rio de Janeiro, Brazil. The full address is Rua Porto Calvo, Santa Luzia, Monjolos, São Gonçalo, Rio de Janeiro.
ETE APOLO serves a population of approximately 25,972 people, classifying it as a medium-sized agglomeration under Brazilian wastewater treatment standards.
The treated effluent from ETE APOLO is likely discharged into local water bodies that drain into Guanabara Bay, which then flows into the Atlantic Ocean.
ETE APOLO operates under Brazilian national wastewater treatment regulations, which are enforced by state environmental agencies such as INEA in Rio de Janeiro. Plants of this scale are typically required to meet secondary treatment standards to protect water quality.
For medium-sized agglomerations in Brazil, secondary treatment is standard, often involving biological processes such as activated sludge or aerated lagoons. Advanced treatment may be required if the discharge is into sensitive water bodies.
