CANDILLARGUES bourg Wastewater Treatment Plant, Candillargues, Occitanie

CANDILLARGUES bourg is a wastewater treatment facility located in Candillargues, a commune in the Hérault department of Occitanie, southern France. The plant serves a population of approximately 1,700 residents and is situated near the Mediterranean coast, less than 10 km from the shoreline. 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. Its designed capacity is 2,500 m³/day, and it currently discharges 303.28 m³/day of treated wastewater. As a French facility, it operates under national regulations transposing EU directives, with permits issued by the local water agency (Agence de l'Eau). The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The coastal environment supports diverse marine life and is an important ecological zone. The plant's advanced treatment helps protect the sensitive coastal waters from nutrient pollution and other contaminants.

The plant discharges into the local watershed that flows into the Mediterranean Sea near the Gulf of Lion. This coastal area supports seagrass meadows and diverse marine species, making it ecologically sensitive. Advanced treatment reduces nutrient loads, helping to prevent eutrophication and protect the marine ecosystem.
