CHAMOUSSET PONT ROYAL Wastewater Treatment Plant, Chamousset, France

CHAMOUSSET PONT ROYAL is a wastewater treatment plant located in Chamousset, in the Auvergne-Rhone-Alpes region of France. It serves a population of approximately 2,468 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its treated effluent is discharged into the local watershed. The plant provides secondary treatment, which is the minimum standard required by the EU UWWTD for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 3,050 cubic meters per day and currently treats an average daily volume of 440 cubic meters, indicating ample reserve capacity for future growth or seasonal variations. The treated wastewater from CHAMOUSSET PONT ROYAL is discharged into the local river system, which ultimately flows into the Rhone River basin. The Rhone is a major European river that drains into the Mediterranean Sea. By treating wastewater to secondary standards, the plant helps protect the ecological quality of the receiving water bodies and supports the biodiversity of the Rhone watershed.

The plant discharges into the local watershed, which is part of the Rhone River basin. The Rhone flows through southeastern France and into the Mediterranean Sea, supporting diverse aquatic life and providing water for agriculture and communities. The region's Alpine terrain contributes to seasonal flow variations, and the plant's secondary treatment helps maintain water quality standards downstream.
