KALLNACH Wastewater Treatment Plant, Kallnach, Bern, Switzerland

KALLNACH is a wastewater treatment plant located in Kallnach, a municipality in the Verwaltungskreis Seeland of Bern, Switzerland. The facility serves a population of approximately 1,500 and is part of the region's municipal wastewater infrastructure. The plant employs advanced treatment processes, ensuring a high level of pollutant removal. It has a designed capacity of 3,600 m³/day and currently discharges an average of 680.88 m³/day of treated wastewater. As a Swiss facility, it operates under the national water protection ordinance (Gewässerschutzverordnung), which sets stringent standards for effluent quality. The treated effluent is discharged into local water bodies that eventually drain into the Aare River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic ecosystems and is a critical waterway for Europe. The plant's advanced treatment helps protect downstream water quality and aquatic life.

The treated wastewater from KALLNACH enters the local drainage network, which flows into the Aare River and ultimately the Rhine River. The Rhine basin is ecologically significant, supporting diverse fish populations and migratory birds. The plant's advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream lakes and the North Sea.
