Overview
MAENNEDORF wastewater treatment plant serves the municipality of Männedorf in Zürich, Switzerland. It is located on the shore of Lake Zurich, treating wastewater from a population of approximately 13,825.
The MAENNEDORF wastewater treatment plant is situated in Männedorf, a municipality in the district of Meilen in the canton of Zürich, Switzerland. The plant serves a population of about 13,825 residents and is located along the northern shore of Lake Zurich, a major water body in the region. As a Swiss wastewater treatment facility, the plant operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates stringent treatment standards to protect water quality. For a community of this size, secondary treatment with nutrient removal is typically required to meet the high environmental standards of the country, particularly given the sensitivity of Lake Zurich as a drinking water source and recreational area. The treated effluent from the plant is discharged into Lake Zurich, which is part of the Rhine basin. Lake Zurich drains via the Limmat River, which flows into the Aare River and eventually into the Rhine, reaching the North Sea. The plant plays a crucial role in maintaining the water quality of Lake Zurich, supporting aquatic life and safeguarding the lake's ecological health.
Environmental context
The MAENNEDORF plant discharges into Lake Zurich, a deep, oligotrophic lake that serves as a drinking water reservoir for the region. The lake drains via the Limmat River into the Aare and then the Rhine, ultimately reaching the North Sea. Protecting Lake Zurich from nutrient pollution is critical to prevent algal blooms and maintain water clarity, supporting diverse aquatic life and recreational uses.
