The plant discharges into the Strei River, a tributary of the Mureș River, which flows into the Tisza River and then the Danube before reaching the Black Sea. The Mureș River basin supports diverse aquatic life and is an important ecological corridor in the Carpathian region. The advanced treatment helps reduce nutrient loading, protecting downstream water quality in this sensitive watershed.
