The plant serves a population of about 24,314 residents in the coastal region of Niterói, which is part of the Greater Rio de Janeiro metropolitan area. As a municipal facility, it plays a key role in managing wastewater from this growing urban area. The plant operates under Brazil's national environmental regulations, which require appropriate treatment for discharges into sensitive coastal waters. For a plant of this scale serving approximately 24,000 people, secondary treatment is typically expected to meet effluent quality standards. The designed capacity is noted as 1.00, though the unit is unspecified, indicating the plant's intended scale. The plant's treated effluent is discharged into the coastal waters of the Atlantic Ocean near Niterói, which is part of the Guanabara Bay watershed. This bay is an ecologically important estuary that supports diverse marine life and is a key economic and recreational resource for the region. Proper treatment at ETE ITAIPU helps reduce nutrient and pollutant loads, protecting water quality and aquatic habitats in this sensitive coastal environment.

ETE ITAIPU discharges into the Atlantic Ocean via the coastal waters of Niterói, which are part of the Guanabara Bay ecosystem. Guanabara Bay is a large, semi-enclosed estuary that receives freshwater from several rivers and supports mangroves, fish, and bird species. The bay's health is critical for local fisheries, tourism, and biodiversity, making effective wastewater treatment essential to prevent eutrophication and contamination.
