Overview
Beaulieu-sous-la-Roche's advanced treatment plant serves 1,617 people in Pays de la Loire, France. It discharges treated wastewater into the local watershed, ultimately reaching the Atlantic Ocean.
The Beaulieu-sous-la-Roche wastewater treatment plant, known as BEAULIEU SOUS LA ROCHE la Guissiere, is located in the commune of Beaulieu-sous-la-Roche in the Vendée department of Pays de la Loire, France. This facility serves a population of approximately 1,617 residents, making it a small-scale municipal treatment plant typical of rural French communities. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,000 cubic meters per day and a current discharge volume of 288.47 cubic meters per day, the plant operates well within its capacity. As a French facility, it is subject to national regulations transposing EU directives, with permits issued by the local water agency (Agence de l'Eau Loire-Bretagne). The treated effluent is discharged into the local hydrographic network, which drains into the Atlantic Ocean via the Vendée coastal rivers. The plant plays a key role in protecting the region's water quality, particularly the nearby wetlands and coastal ecosystems that support diverse aquatic life and migratory birds.
Environmental context
The plant discharges into small streams that flow toward the Atlantic coast of Vendée. This region features ecologically sensitive coastal wetlands and estuaries that provide critical habitat for migratory birds and fish species. The advanced treatment helps minimize nutrient loading into these waters, reducing the risk of eutrophication in downstream coastal areas.
