DUEBENDORF Wastewater Treatment Plant, Dübendorf, Zürich, Switzerland

The DUEBENDORF wastewater treatment plant is located in Dübendorf, a municipality in the canton of Zürich, Switzerland. It serves a population of approximately 55,542 people, classifying it as a medium-sized agglomeration under Swiss water protection standards. The plant is situated near the Glatt River, which flows through the Glatt Valley and ultimately drains into the Rhine. As a Swiss wastewater facility, DUEBENDORF is subject to the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment for plants serving agglomerations over 10,000 people. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a substantial infrastructure to handle the region's wastewater. Swiss regulations typically require mechanical-biological treatment with phosphorus removal and, in sensitive areas, nitrogen removal. The treated effluent is discharged into the Glatt River, a small river that flows through the Zürich region and joins the Rhine near Koblenz. The Rhine is a major European waterway, and the plant's discharge contributes to the overall water quality in the Rhine basin. The plant plays a critical role in protecting the local aquatic ecosystem and downstream water bodies from pollution.

The DUEBENDORF plant discharges into the Glatt River, which flows through the Glatt Valley and joins the Rhine River near Koblenz. The Rhine ultimately drains into the North Sea. The Glatt River supports diverse aquatic life and is an important corridor for fish migration. The plant's operations are crucial for maintaining water quality in this sensitive river system, which is part of the larger Rhine basin, a region with high ecological and economic significance.
