Bergun_Bravuogn Wastewater Treatment Plant, Bergün Filisur, Switzerland

The Bergun_Bravuogn wastewater treatment plant is located in Bergün Filisur, in the canton of Graubünden, Switzerland. It serves a population of approximately 874 residents, providing secondary treatment as part of the municipal wastewater infrastructure. The plant is situated in the Alpine region, which influences its operational context. As a secondary treatment facility, the plant meets the standard requirements under Swiss wastewater regulations, which align with the EU Urban Waste Water Treatment Directive for smaller agglomerations. The designed capacity of 3,333 cubic meters per day indicates the plant is sized to handle peak flows, with current discharge volumes well below capacity. The treated effluent is discharged into the local watershed, which drains into the Albula River, a tributary of the Rhine. The Rhine ultimately flows into the North Sea. The Alpine environment supports sensitive aquatic ecosystems, and the plant's treatment helps protect water quality in this ecologically important region.

The plant discharges into the Albula River, part of the Rhine basin, which flows through Switzerland, Germany, and the Netherlands to the North Sea. The Alpine watershed supports diverse aquatic life, including fish species adapted to cold, oxygen-rich waters. The secondary treatment reduces organic pollutants and suspended solids, helping maintain the ecological health of the river system downstream.
