The plant serves a population of around 151,000 people, placing it in the large agglomeration category for regulatory purposes. It is situated in the southeastern region of Brazil, an area characterized by tropical climate and significant agricultural and industrial activity. As a large-scale facility, ETE PARAIBA is expected to meet the treatment standards set by Brazil's National Environment Council (CONAMA) and the National Water Agency (ANA). These regulations typically require secondary treatment for municipal wastewater to protect water quality. The plant's designed capacity is 1. The plant discharges treated effluent into local water bodies that ultimately drain into the Atlantic Ocean via the Paraíba do Sul River basin. This river is a critical water source for the region, supporting agriculture, industry, and drinking water supplies. Proper treatment at ETE PARAIBA helps mitigate nutrient and pollutant loads that could impact downstream ecosystems and coastal waters.

The plant is located in the Paraíba do Sul River basin, which flows through the states of São Paulo, Rio de Janeiro, and Minas Gerais before emptying into the Atlantic Ocean near Campos dos Goytacazes. This river supports diverse aquatic life and is a vital resource for regional water supply. The downstream coastal environment includes important estuarine and marine habitats that are sensitive to nutrient pollution and require effective wastewater treatment to maintain ecological balance.
