Overview
PERROYAIBFP is a wastewater treatment plant serving Perroy, Vaud, Switzerland. It treats wastewater from approximately 3,058 people and operates under Swiss water protection regulations.
PERROYAIBFP is a wastewater treatment plant located in Perroy, a municipality in the District of Nyon, Canton of Vaud, Switzerland. The plant serves a population of approximately 3,058 people, placing it in the small-to-medium agglomeration category under Swiss water management frameworks. It is situated near the shores of Lake Geneva, a major freshwater body in Western Europe. Switzerland enforces stringent wastewater treatment standards under its Water Protection Act (Gewässerschutzgesetz), which requires appropriate treatment for all discharges into water bodies. For plants of this scale, secondary treatment with nutrient removal is typical, especially in sensitive areas like the Lake Geneva basin. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a modest facility tailored to local needs. The plant's treated effluent ultimately reaches Lake Geneva, which drains via the Rhone River into the Mediterranean Sea. Lake Geneva is a critical freshwater resource for drinking water, recreation, and biodiversity. The plant plays a key role in protecting the lake's water quality from nutrient pollution and pathogens, supporting the ecological health of this alpine lake and downstream ecosystems.
Environmental context
The plant discharges into the Lake Geneva watershed, which feeds into the Rhone River and eventually the Mediterranean Sea. Lake Geneva is a large, deep alpine lake that supports diverse aquatic life, including endemic fish species and migratory birds. Nutrient loading from wastewater can lead to eutrophication, so effective treatment is essential to preserve water quality and ecological balance in this sensitive lacustrine environment.
Frequently asked questions
PERROYAIBFP is located at 13, Chemin de Sus-Craux, Perroy, in the District of Nyon, Canton of Vaud, Switzerland. It is situated near the northern shore of Lake Geneva.
The plant serves approximately 3,058 people, classifying it as a small-to-medium agglomeration under Swiss wastewater management standards.
The treated effluent from PERROYAIBFP is discharged into the Lake Geneva watershed. Lake Geneva drains via the Rhone River into the Mediterranean Sea.
The plant operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates appropriate treatment levels to protect water bodies. For plants serving around 3,000 people, secondary treatment with nutrient removal is typically required, especially in sensitive areas like the Lake Geneva basin.
In Switzerland, wastewater treatment plants serving populations of 2,000 to 10,000 usually employ secondary biological treatment with phosphorus removal to meet strict effluent standards. This helps prevent eutrophication in receiving waters like Lake Geneva.
