Overview
ESSERT ROMAND MORZINE is a wastewater treatment plant in Essert-Romand, France, serving over 51,000 people. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
ESSERT ROMAND MORZINE is a wastewater treatment plant located in Essert-Romand, in the Auvergne-Rhône-Alpes region of France. The plant serves a population of approximately 51,021 people, classifying it as a large agglomeration under EU regulations. It is part of the SIVOM de la Vallée d'Aulps, a municipal syndicate managing wastewater services in the valley. As a facility serving over 50,000 people, ESSERT ROMAND MORZINE is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum. For larger agglomerations in sensitive areas, tertiary treatment may be required to reduce nutrients like nitrogen and phosphorus. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the community's wastewater load. The plant discharges treated effluent into the local watershed, which drains into the Dranse River and eventually into Lake Geneva (Lac Léman), one of Europe's largest freshwater lakes. Lake Geneva is ecologically sensitive, supporting diverse aquatic life and serving as a critical water resource. The plant's operation helps protect this downstream environment from nutrient pollution and pathogens.
Environmental context
The plant's treated effluent flows into the Dranse River, a tributary of Lake Geneva (Lac Léman), which is the largest alpine lake in Europe. Lake Geneva supports a rich ecosystem, including endemic fish species and migratory birds, and provides drinking water for millions. The watershed is sensitive to nutrient loading, which can cause algal blooms. The plant's compliance with EU standards helps mitigate these risks.
Frequently asked questions
ESSERT ROMAND MORZINE is located in Essert-Romand, in the Haute-Savoie department of the Auvergne-Rhône-Alpes region, France. The address is SIVOM de la Vallée d'Aulps, 184, Allée des Communailles, Le Déjeuner, Essert-Romand.
The plant discharges treated effluent into the local watershed, which flows into the Dranse River and ultimately into Lake Geneva. The exact discharge point is managed to meet regulatory standards for water quality.
The plant protects the Dranse River and Lake Geneva by treating wastewater before release. This helps maintain water quality in these water bodies, which are important for ecology and recreation.
As a plant serving over 50,000 people, it is classified as a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires secondary treatment as a minimum, and tertiary treatment if the receiving waters are sensitive to eutrophication.
In France, plants serving around 51,000 people typically employ secondary biological treatment, such as activated sludge or biofiltration. In sensitive areas like the Lake Geneva basin, additional nutrient removal (tertiary treatment) may be required to meet phosphorus and nitrogen limits.
