Overview
Cuarny wastewater treatment plant in Vaud, Switzerland serves 135 people with secondary treatment. It discharges 61.28 m³/day and operates under Swiss water protection regulations.
Cuarny wastewater treatment plant is located in the municipality of Cuarny, in the Vaud canton of Switzerland. It serves a small population of 135 residents, reflecting the rural character of the area. The plant is situated in the Jura-Nord vaudois district, near the Clos-du-Moulin area. The plant provides secondary treatment, which is the standard biological treatment required under Swiss federal water protection law (Gewässerschutzgesetz). With a designed capacity of 317 m³/day and a current discharge volume of 61.28 m³/day, the facility operates well below its capacity. Swiss regulations mandate that all wastewater treatment plants meet strict effluent standards to protect receiving waters. The treated effluent likely discharges into a local stream or river within the Rhone basin, eventually reaching Lake Geneva (Lac Léman) and then the Mediterranean Sea via the Rhone River. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution.
Environmental context
The plant's discharge enters a small watercourse in the Vaud countryside, part of the Rhone basin. This water flows toward Lake Geneva, a large alpine lake that supports diverse aquatic life and is a critical drinking water source. Downstream, the Rhone River carries water through southern France to the Mediterranean Sea. Protecting this chain from nutrient loading is essential for preventing eutrophication in Lake Geneva and maintaining water quality in the Rhone delta.
