GINGINS CHESEREX Wastewater Treatment Plant, Gingins, Vaud, Switzerland

GINGINS CHESEREX is an advanced wastewater treatment plant located in Gingins, within the District of Nyon in the canton of Vaud, Switzerland. The facility serves a small population of 973 residents, reflecting its role in a rural or suburban community near the French border. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1625 m³/day and a current discharge volume of 441.67 m³/day, the plant operates well below its capacity, indicating room for future growth. Swiss wastewater treatment plants are regulated under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates high treatment standards to protect sensitive water bodies. The treated effluent from GINGINS CHESEREX ultimately drains into the Rhône River basin via local streams, contributing to the water quality of Lake Geneva (Lac Léman) and the Rhône River. The plant helps protect the aquatic ecosystem of the region, which supports diverse fish populations and is an important water resource for Switzerland and downstream France.

The plant discharges into local watercourses that flow into the Rhône River basin, eventually reaching Lake Geneva and the Rhône River. Lake Geneva is a large, deep alpine lake that supports diverse aquatic life, including endemic fish species and migratory birds. The advanced treatment at GINGINS CHESEREX helps minimize nutrient loading and protects the ecological balance of this sensitive watershed.
