Overview
MONTAGNAC bourg is an advanced wastewater treatment plant in Montagnac, Occitanie, France, serving 4,300 people with a designed capacity of 5,000 m³/day and an average discharge of 767 m³/day.
MONTAGNAC bourg is a municipal wastewater treatment plant located in Montagnac, a commune in the Hérault department of Occitanie, southern France. The plant serves a population of approximately 4,300 residents and is designed to handle up to 5,000 cubic meters of wastewater per day, with an average daily discharge of 767 cubic meters. 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. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) and possibly tertiary filtration or disinfection, ensuring high-quality effluent before discharge. The treated effluent is discharged into local watercourses that eventually flow into the Mediterranean Sea via the Hérault River or coastal lagoons. The plant plays a key role in protecting the sensitive aquatic ecosystems of the region, including the Thau Lagoon and the Mediterranean coastal zone, which support diverse marine life and are important for tourism and fisheries.
Environmental context
The plant discharges into the Hérault River basin, which flows into the Mediterranean Sea near the Thau Lagoon, a ecologically sensitive coastal lagoon that supports oyster farming and diverse aquatic species. The advanced treatment helps minimize nutrient loading and protect downstream water quality in this region, which is subject to EU regulations for sensitive areas.
