Overview
LE BIOT Gys is a secondary treatment plant in La Baume, France, serving 100 people. It discharges 17.84 m³/day and is located within 10 km of the coast.
LE BIOT Gys is a municipal wastewater treatment plant located in La Baume, within the Auvergne-Rhône-Alpes region of France. The facility serves a small population of 100 people, reflecting its role in a rural or peri-urban setting near Thonon-les-Bains. The plant is situated in the Haute-Savoie department, close to the shores of Lake Geneva. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 100 m³/day and an actual discharge volume of 17.84 m³/day, the facility operates well below its capacity. French wastewater plants are regulated under national transposition of EU directives, with permits issued by local authorities. The treated effluent from LE BIOT Gys ultimately discharges into the Lake Geneva basin, one of the largest freshwater lakes in Western Europe. Lake Geneva supports diverse aquatic life and serves as a critical drinking water source for the region. The plant's proximity to the coast (within 10 km) means its discharge can influence the lake's water quality, making proper treatment essential for protecting this sensitive ecosystem.
Environmental context
The plant discharges into the Lake Geneva watershed, which drains through the Rhône River to the Mediterranean Sea. Lake Geneva is an ecologically sensitive freshwater body that supports diverse aquatic life, including endemic fish species, and serves as a major migratory corridor for birds. The lake's oligotrophic status requires strict nutrient control to prevent eutrophication.
