MORNAS Wastewater Treatment Plant, Mornas, France - Advanced Treatment for 2,600 Residents

The MORNAS wastewater treatment plant is located in Mornas, a commune in the Vaucluse department of Provence-Alpes-Cote d'Azur, France. It serves a population of approximately 2,600 residents, classifying it as a small agglomeration under French and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The facility provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 2,700 cubic meters per day and currently treats an average daily flow of 463.84 cubic meters, indicating significant spare capacity. This advanced treatment level likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into a local watercourse that ultimately drains into the Rhone River, one of Europe's major rivers flowing into the Mediterranean Sea. The Rhone basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The plant's advanced treatment helps minimize nutrient and pollutant loads, contributing to the ecological health of the downstream environment.

The MORNAS plant discharges into a tributary of the Rhone River, which flows southward through the Camargue delta into the Mediterranean Sea. The Rhone basin is ecologically significant, supporting diverse aquatic life and serving as a key migratory route for fish such as the European eel. The advanced treatment at this plant helps reduce nutrient enrichment and protect downstream water quality in this sensitive riverine and coastal ecosystem.
