PUJAUT Wastewater Treatment Plant, Pujaut, Occitanie, France

PUJAUT is a wastewater treatment plant located in Pujaut, a commune in the Gard department of Occitanie, southern France. The plant serves a population of 3,006 and has a designed capacity of 4,000 cubic meters per day, indicating it is sized for moderate local demand. As part of France's municipal infrastructure, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on population served and receiving environment sensitivity. The plant employs advanced treatment processes, which go beyond the standard secondary treatment to remove nutrients and other pollutants. This level of treatment is often required for discharges into sensitive areas or to meet stringent water quality standards. The plant's discharge volume of 536.27 cubic meters per day reflects its current operational load. Treated effluent from PUJAUT is discharged into local watercourses that ultimately drain into the Rhône River basin. The Rhône flows into the Mediterranean Sea, supporting diverse aquatic ecosystems and important migratory fish species. The advanced treatment helps protect downstream water quality and the ecological health of the Rhône delta and coastal waters.

PUJAUT is located inland in the Rhône River basin, which drains into the Mediterranean Sea via the Rhône delta. The region supports diverse aquatic life, including migratory fish such as eels and sturgeon. Advanced treatment at the plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and protect the sensitive coastal ecosystems of the Camargue and the Gulf of Lion.
