GRYON Wastewater Treatment Plant, Gryon, Vaud, Switzerland

GRYON is a wastewater treatment plant located in Gryon, a municipality in the canton of Vaud, Switzerland. The plant serves a population of about 3,741 people, reflecting its role in managing domestic wastewater for this Alpine community. As a Swiss facility, it operates within the country's stringent water protection framework, which mandates advanced treatment to safeguard sensitive water bodies. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating a small-scale facility appropriate for its population size. Swiss regulations typically require tertiary treatment for plants discharging into sensitive environments, which is common in the Alpine region. The plant's operational status is active, supporting the local infrastructure. The treated effluent likely discharges into a local stream or river within the Rhône basin, as Gryon is situated in the Alpine foothills near the Rhône River. This water eventually flows into Lake Geneva (Lac Léman) and then via the Rhône to the Mediterranean Sea. The plant plays a key role in protecting downstream water quality, including aquatic habitats in the Rhône watershed.

GRYON plant is located in the Swiss Alps, within the Rhône River basin. The treated wastewater likely enters a local tributary that feeds into the Rhône, which flows through Lake Geneva before reaching the Mediterranean Sea. This watershed supports diverse aquatic life, including fish species such as brown trout, and is ecologically sensitive due to its Alpine character and downstream lake ecosystem.
