Mouguerre Nouvelle Wastewater Treatment Plant | Mouguerre, Nouvelle-Aquitaine, France

Mouguerre Nouvelle is an advanced wastewater treatment plant located in Mouguerre, within the Pyrénées-Atlantiques department of Nouvelle-Aquitaine, France. It serves a population of approximately 2,900 residents and has a designed capacity of 12,000 m³/day, with a current discharge volume of 517.35 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The plant's scale places it in the small agglomeration category, but its advanced treatment level suggests it discharges into a sensitive environment. The treated effluent is discharged into the local watershed, which ultimately drains into the Bay of Biscay via the Adour River. The plant's proximity to the coast (within 10 km) underscores its role in protecting coastal water quality and marine ecosystems from nutrient pollution.

The plant discharges into the Adour River basin, which flows into the Bay of Biscay, a part of the Atlantic Ocean. The coastal waters support diverse marine life, including fish and migratory species. Advanced treatment helps reduce nutrient loads, protecting the estuary and coastal zone from eutrophication and algal blooms.
