Overview
MARIGNIER CLUSES wastewater treatment plant serves Vougy, Auvergne-Rhône-Alpes, France, handling a population equivalent of 73,332. It operates under the EU Urban Waste Water Treatment Directive.
The MARIGNIER CLUSES wastewater treatment plant is located in Vougy, within the Auvergne-Rhône-Alpes region of France. It serves a population equivalent of 73,332, classifying it as a medium-to-large agglomeration under EU regulations. The plant is situated near the Autoroute Blanche in the Haute-Savoie department. As a French facility of this scale, the plant is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations between 10,000 and 150,000 population equivalent, secondary treatment is mandatory, with tertiary treatment required if the receiving waters are sensitive areas. The plant's designed capacity is 1. The plant's treated effluent discharges into the local watershed, which ultimately drains into the Arve River and then the Rhône River, flowing towards the Mediterranean Sea. The Arve River is a significant tributary of the Rhône, supporting diverse aquatic life and providing water for agriculture and recreation in the region.
