The surrounding region is ecologically significant, supporting diverse aquatic life and contributing to the overall health of the Miño-Sil river system. The plant plays a key role in protecting local water quality and downstream ecosystems.

The plant discharges into the Sil River basin, a tributary of the Miño River, which flows into the Atlantic Ocean at the Ría de Vigo. The Miño-Sil system is one of the most important river basins in Galicia, supporting diverse aquatic habitats and migratory fish species. The region's mountainous terrain and Atlantic climate contribute to high rainfall, making effective wastewater treatment crucial for maintaining water quality in this ecologically sensitive area.
