Overview
REDESSAN wastewater treatment plant in Redessan, Occitanie, France, serves 3,340 people with advanced treatment and a designed capacity of 5,000 m³/day.
The REDESSAN wastewater treatment plant is located in Redessan, a commune in the Gard department of Occitanie, southern France. It serves a population of approximately 3,340 people, placing it in the small agglomeration category under French regulations. 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. With a designed capacity of 5,000 m³/day and an average discharge volume of 595.85 m³/day, the facility operates well within its capacity. French wastewater treatment plants are regulated under national decrees transposing EU directives, with permits issued by the local prefecture. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River via the Gardon or Vistre rivers. The Rhône flows into the Mediterranean Sea, making the plant's advanced treatment important for protecting downstream aquatic ecosystems and coastal water quality in the Camargue region.
Environmental context
The plant discharges into the Gardon or Vistre river system, tributaries of the Rhône River, which flows into the Mediterranean Sea. The downstream environment includes the Camargue delta, a ecologically sensitive area supporting diverse birdlife and aquatic habitats. Advanced treatment helps reduce nutrient loading, protecting the Rhône's water quality and the Mediterranean coastal zone from eutrophication.
