The plant discharges into the Kamp River, a tributary of the Danube, which flows into the Black Sea. The Kamp River supports diverse aquatic life and is part of a sensitive watershed where nutrient pollution can impact downstream ecosystems. Advanced treatment at this plant helps reduce nutrient loads, protecting the river's ecological balance and the broader Danube basin.
