Overview
MIREPOIX wastewater treatment plant serves Mirepoix in Occitanie, France. It treats wastewater for approximately 5,995 people under EU Urban Waste Water Treatment Directive standards.
The MIREPOIX wastewater treatment plant is located in Mirepoix, a commune in the Ariège department of Occitanie, southern France. The facility serves a population of approximately 5,995 people, placing it in the small-to-medium agglomeration category under European Union classification. As a French plant, MIREPOIX operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The directive also mandates appropriate treatment to protect sensitive areas, which may include nutrient removal if the receiving water body is designated as sensitive. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Hers-Vif River, a tributary of the Ariège River, and then into the Garonne River before reaching the Atlantic Ocean. The facility plays a key role in protecting the water quality of these rivers and supporting the ecological health of the Garonne basin.
Environmental context
The MIREPOIX plant discharges into the Hers-Vif River, which flows into the Ariège River, a major tributary of the Garonne River. The Garonne basin supports diverse aquatic life and is important for migratory fish species. The plant's treatment helps maintain water quality in this ecologically sensitive river system, which ultimately drains into the Atlantic Ocean via the Gironde estuary.
