Overview
VIELLE AURE wastewater treatment plant serves the commune of Vielle-Aure in Occitanie, France. It treats wastewater from approximately 9,000 people and discharges into the local watershed.
VIELLE AURE is a wastewater treatment plant located in Vielle-Aure, a commune in the Hautes-Pyrénées department of Occitanie, southern France. The plant serves a population of around 9,000 people, making it a medium-sized agglomeration under French regulations. It is situated in the Pyrenees mountain region, near the border with Spain. As a French wastewater facility, VIELLE AURE operates under the European Union's Urban Waste Water Treatment Directive (UWWTD) 91/271/EEC, transposed into French law. For agglomerations of this size, the directive requires at least secondary treatment, with more stringent treatment if the discharge enters a sensitive area. It is expected to meet these regulatory standards. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Adour River basin. The Adour flows northward through the Pyrenees foothills and eventually reaches the Bay of Biscay in the Atlantic Ocean. The surrounding environment includes mountainous terrain and sensitive aquatic habitats that rely on proper wastewater treatment to maintain water quality.
Environmental context
VIELLE AURE discharges into the local watershed, which is part of the Adour River basin. The Adour River flows through the Pyrenees region and empties into the Bay of Biscay, a coastal area of the Atlantic Ocean. The downstream environment supports diverse aquatic life, including fish species such as salmon and trout, and the river's ecological health depends on effective wastewater treatment to prevent nutrient pollution and maintain oxygen levels.
