ECLEPENS Wastewater Treatment Plant, Eclépens, Vaud, Switzerland

The ECLEPENS wastewater treatment plant is located in the industrial zone of Eclépens, a municipality in the District of Morges, Vaud, Switzerland. This facility serves a population of 1,213 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. As a Swiss plant, it operates under national regulations aligned with the EU Urban Waste Water Treatment Directive, which mandates advanced treatment for sensitive areas. The plant has a designed capacity of 1,975 m³/day and currently discharges 550.61 m³/day, indicating ample reserve capacity. The plant's discharge ultimately reaches the Rhône River basin via local waterways, contributing to the protection of Lake Geneva and the broader Mediterranean ecosystem. Its coastal proximity underscores the importance of advanced treatment in preventing nutrient enrichment in downstream waters.

The plant discharges into local streams that drain into the Rhône River, which flows into Lake Geneva and eventually the Mediterranean Sea. This watershed supports diverse aquatic life and is ecologically sensitive due to its role in maintaining water quality for downstream ecosystems. Advanced treatment helps minimize nutrient loading and protects the lake from eutrophication.
