GLANDAPEC Wastewater Treatment Plant, Gland, Vaud, Switzerland

GLANDAPEC is a wastewater treatment plant located in Gland, within the canton of Vaud, Switzerland. It serves a population equivalent of approximately 31,218, placing it in the medium agglomeration category. The plant is situated along Route Suisse, near the shores of Lake Geneva, and is part of the region's municipal wastewater infrastructure. As a Swiss facility, GLANDAPEC operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment standards to protect water bodies. For agglomerations of this size, secondary treatment with nutrient removal is typically required, especially in sensitive areas like the Lake Geneva basin. The plant discharges into the local watershed that drains into Lake Geneva (Lac Léman), one of Europe's largest freshwater lakes. Lake Geneva is a critical ecological resource, supporting diverse aquatic life and serving as a drinking water source for the region. Downstream, the lake's outflow forms the Rhône River, which flows through France into the Mediterranean Sea. The plant's performance is vital for maintaining water quality in this internationally important water body.

GLANDAPEC discharges into the Lake Geneva watershed, which ultimately drains via the Rhône River into the Mediterranean Sea. Lake Geneva is a large, deep lake with significant ecological value, supporting fish species such as Arctic char and whitefish, and providing habitat for migratory birds. The plant's location near the lake requires stringent treatment to prevent eutrophication and protect recreational and drinking water uses.
