The plant plays a role in safeguarding the ecological health of these water bodies and the downstream environment.

The plant discharges into the Strei River basin, which flows into the Mureș River, a major tributary of the Tisza River, and ultimately the Danube River. The area supports diverse aquatic life and is part of a broader ecosystem that benefits from pollution control measures. The plant's secondary treatment helps reduce organic load and nutrients, protecting downstream habitats.
