BUCHSFURTHOF Wastewater Treatment Plant, Buchs (ZH), Switzerland

BUCHSFURTHOF is a wastewater treatment plant located in Buchs (ZH), a municipality in the canton of Zürich, Switzerland. The plant serves a population of around 10,605 people, placing it in the small to medium agglomeration category. It is situated in the Furttal region, north of Zürich, and is part of the local infrastructure managed by the municipality. As a Swiss plant, BUCHSFURTHOF operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates appropriate treatment standards based on the size of the agglomeration and the sensitivity of the receiving water body. For plants serving between 2,000 and 15,000 population equivalents, secondary treatment with nutrient removal is typically required. It is expected to meet these national standards. The treated effluent from BUCHSFURTHOF is discharged into local watercourses that eventually drain into the Rhine River basin. The Rhine is a major European river flowing through Switzerland, Germany, and the Netherlands before reaching the North Sea. The plant's location inland and away from the coast reduces direct marine impact, but its discharge contributes to the overall water quality of the Rhine catchment, which supports diverse aquatic ecosystems and is used for drinking water supply downstream.

BUCHSFURTHOF discharges into local streams that feed into the Rhine River, which flows through Switzerland, Germany, and the Netherlands to the North Sea. The Rhine basin is ecologically sensitive, supporting diverse fish species and serving as a critical water source for millions. The plant's nutrient removal helps protect downstream water quality in this internationally important river system.
