Overview
HABERE POCHE wastewater treatment plant serves Habère-Poche in Auvergne-Rhône-Alpes, France. It provides advanced treatment for a population of 2,189, with a designed capacity of 3,150 m³/day.
HABERE POCHE is a wastewater treatment plant located in Habère-Poche, a commune in the Haute-Savoie department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 2,189 people and is situated in a mountainous area near the Swiss border. The plant operates with advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive receiving waters. The plant has a designed capacity of 3,150 m³/day and currently treats an average daily flow of 390.51 m³, indicating ample reserve capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Dranse River and then into Lake Geneva (Lac Léman), one of Europe's largest freshwater lakes. Lake Geneva is ecologically sensitive and supports diverse aquatic life, making advanced treatment crucial for protecting water quality and preventing eutrophication.
Environmental context
The plant discharges into the local watershed that feeds the Dranse River, a tributary of Lake Geneva (Lac Léman). Lake Geneva is a large, deep alpine lake that supports a rich ecosystem, including endemic fish species and migratory birds. The lake is also a major drinking water source for the region. Advanced treatment at this plant helps reduce nutrient loading, protecting the lake from algal blooms and maintaining its ecological health.
Frequently asked questions
HABERE POCHE is located in Habère-Poche, a commune in the Haute-Savoie department of the Auvergne-Rhône-Alpes region in eastern France, near the Swiss border.
The plant serves a population of approximately 2,189 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is discharged into the local watershed, which flows into the Dranse River and ultimately into Lake Geneva (Lac Léman).
The plant provides advanced treatment, which includes nutrient removal beyond secondary treatment. This is typical for plants discharging into sensitive areas like Lake Geneva.
Under the EU UWWTD, agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have secondary treatment. HABERE POCHE exceeds this requirement with advanced treatment, reflecting the sensitivity of the receiving water body.
