The plant serves a small population of around 3,825 people, reflecting the scale of this inland community in the southern region of the country. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. For a plant of this size in Brazil, secondary treatment aligns with national regulations under CONAMA resolutions, which set effluent quality standards for wastewater discharges. The plant reports a daily discharge volume of 367.20 cubic meters. The treated effluent is released into local water bodies that drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and is vital for water supply, agriculture, and hydropower in the region. Proper treatment at ETE TERRA BOA helps protect downstream water quality and ecological health.

The plant discharges into local streams that flow into the Paraná River basin, which ultimately drains into the Río de la Plata estuary. This watershed supports a variety of freshwater species and is an important resource for communities and industries. Secondary treatment reduces organic pollutants, helping to maintain water quality in the receiving water bodies and minimize impacts on downstream ecosystems.
