Overview
ST ANDRE DE SANGONIS wastewater treatment plant serves Saint-André-de-Sangonis, Occitanie, France. It has a designed capacity of 1.00 and serves a population of 6,600.
The ST ANDRE DE SANGONIS wastewater treatment plant is located in Saint-André-de-Sangonis, a commune in the Hérault department of Occitanie, southern France. The plant serves a population of approximately 6,600 residents and has a designed capacity of 1.00, reflecting its role in managing municipal wastewater for this small agglomeration. As a French wastewater facility serving fewer than 10,000 people, the plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving environment. For small agglomerations, secondary treatment is typically mandated unless the discharge is into a less sensitive area. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Hérault River and then into the Mediterranean Sea. This coastal drainage system supports diverse aquatic life and is important for regional water quality, particularly given the agricultural and tourism activities in the Occitanie region.
Environmental context
The plant discharges into the Hérault River basin, which flows southward to the Mediterranean Sea near Agde. The downstream environment includes ecologically sensitive coastal lagoons and wetlands that support migratory birds and fish species. Maintaining proper treatment levels is crucial to prevent nutrient enrichment and protect marine biodiversity in the Gulf of Lion.
