Overview
RASTEAU wastewater treatment plant serves 2,500 people in Rasteau, Provence-Alpes-Côte d'Azur, France. It provides advanced treatment and discharges 446 m³/day of treated effluent.
RASTEAU is a wastewater treatment plant located in Rasteau, a commune in the Vaucluse department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 2,500 residents, classifying it as a small agglomeration under French and EU 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 1,900 m³/day and currently treats 446 m³/day, indicating ample reserve capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River basin. The Rhône flows into the Mediterranean Sea, supporting diverse aquatic ecosystems. The advanced treatment helps minimize nutrient loading and protects downstream water quality in the region.
Environmental context
The plant discharges into a tributary of the Ouvèze River, which flows into the Rhône River near Avignon. The Rhône is a major European river that empties into the Mediterranean Sea. The downstream environment includes ecologically sensitive areas such as the Camargue delta, a critical habitat for migratory birds and aquatic species. Advanced treatment at RASTEAU helps reduce nutrient pollution that could otherwise contribute to eutrophication in the Mediterranean coastal zone.

The plant serves approximately 2,500 people in the commune of Rasteau and surrounding areas.
The treated effluent is discharged into a local watercourse that flows into the Ouvèze River, a tributary of the Rhône River, which ultimately reaches the Mediterranean Sea.
RASTEAU provides advanced treatment, which includes nutrient removal beyond secondary treatment. This is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive.
As a small agglomeration (under 10,000 population equivalent), RASTEAU is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates at least secondary treatment. The plant's advanced treatment exceeds this requirement, likely due to the sensitivity of the receiving waters in the Rhône basin.
