The plant discharges into local streams that flow into the Tietê River, a major tributary of the Paraná River basin. This basin drains into the Río de la Plata estuary, supporting diverse aquatic life and providing water for millions. The region's seasonal rainfall patterns influence flow rates, making consistent treatment important for maintaining ecological balance.
