Overview
ECLAGNENSSIEGEO is an advanced wastewater treatment plant in Goumoëns, Vaud, Switzerland, serving 1,122 people with a capacity of 1,875 m³/day.
ECLAGNENSSIEGEO is an advanced wastewater treatment plant located in the village of Eclagnens, part of the municipality of Goumoëns in the canton of Vaud, Switzerland. The plant serves a population of 1,122 and has a designed capacity of 1,875 cubic meters per day, with a discharge volume of 509.30 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for Swiss plants discharging into sensitive water bodies. Switzerland, though not an EU member, aligns with the EU Urban Waste Water Treatment Directive standards, and advanced treatment is often required for plants in sensitive areas like the Swiss Plateau. The plant's treated effluent likely discharges into a local stream that feeds into the Talent River, a tributary of the Venoge River, which flows into Lake Geneva (Lac Léman). Lake Geneva is a large, ecologically important lake that supports diverse aquatic life and provides drinking water for the region. The advanced treatment helps protect this sensitive ecosystem from eutrophication.
Environmental context
The plant discharges into the local watershed of the Talent River, a tributary of the Venoge River, which flows into Lake Geneva (Lac Léman). Lake Geneva is a large, deep lake that supports diverse aquatic life, including endemic fish species, and serves as a critical drinking water reservoir. Advanced treatment at this plant helps prevent nutrient loading that could lead to algal blooms and oxygen depletion in the lake.
