The plant serves a population of approximately 3,310 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant employs secondary treatment, which is the standard biological process for removing organic matter and suspended solids. As a facility of this size, it operates under Brazil's national environmental regulations, which require adequate treatment before discharge to protect water resources. The plant discharges a daily volume of 777.60 m³ of treated wastewater. The treated effluent is released into local water bodies that drain into the Piabanha River basin, part of the Paraíba do Sul River system. This river is a critical water source for the region, supporting agriculture, industry, and downstream communities. Proper treatment at ETE GRANJA BRASIL helps maintain water quality and ecological balance in this important watershed.

The plant discharges into the Piabanha River basin, which flows into the Paraíba do Sul River, one of Brazil's most important rivers. The Paraíba do Sul ultimately reaches the Atlantic Ocean near Campos dos Goytacazes. The watershed supports diverse aquatic life and provides water for millions of people. Secondary treatment reduces organic pollution, protecting downstream ecosystems and water quality.
