Overview
GRAND BORNAND ST JEAN de SIXT GRAND BORNE is a wastewater treatment plant serving 20,526 people in Saint-Jean-de-Sixt, Auvergne-Rhône-Alpes, France. It operates under the EU Urban Waste Water Treatment Directive.
GRAND BORNAND ST JEAN de SIXT GRAND BORNE is a wastewater treatment plant located in Saint-Jean-de-Sixt, within the Haute-Savoie department of the Auvergne-Rhône-Alpes region in France. The plant serves a population of approximately 20,526, classifying it as a medium-sized agglomeration under EU classification. As a French facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the discharge enters sensitive areas, which are common in the Alpine region due to the presence of lakes and rivers with ecological significance. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Arve River, a tributary of the Rhône. The Rhône flows into the Mediterranean Sea. The Alpine environment supports diverse aquatic life and is an important ecological corridor, making effective treatment essential to protect water quality and biodiversity.
Environmental context
The plant's treated effluent enters the local watershed, which feeds into the Arve River and then the Rhône River, eventually reaching the Mediterranean Sea. The Alpine region is ecologically sensitive, supporting diverse aquatic species and serving as a critical migratory corridor. Protecting water quality in this area is vital for maintaining the health of downstream ecosystems.
