ETE Barbosa Lage is a municipal wastewater treatment plant located in the Barbosa Lage neighborhood of Juiz de Fora, Minas Gerais, Brazil. The plant serves an estimated population of 38,120 people, classifying it as a medium-sized facility within the region's sanitation infrastructure. As a Brazilian wastewater treatment plant, ETE Barbosa Lage is subject to CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997), which set effluent discharge standards and water quality goals. For a plant of this scale, secondary treatment is typically required to meet biochemical oxygen demand (BOD) and total suspended solids (TSS) limits before discharge. The plant's treated effluent is likely discharged into a local watercourse that drains into the Paraibuna River, a major tributary of the Paraiba do Sul River. This river system flows through the states of São Paulo and Rio de Janeiro before reaching the Atlantic Ocean near Campos dos Goytacazes. The downstream waters support diverse aquatic life and are used for water supply, agriculture, and recreation.
Environmental context
The plant's discharge enters the Paraibuna River watershed, which flows into the Paraiba do Sul River, one of Brazil's most important rivers. The Paraiba do Sul ultimately drains into the Atlantic Ocean, supporting coastal ecosystems including mangroves and estuaries. The region's tropical climate and seasonal rainfall patterns influence river flow and dilution capacity, making consistent treatment essential for protecting downstream water quality and aquatic biodiversity.
