Overview
CHALAMONT wastewater treatment plant serves the commune of Chalamont in Auvergne-Rhône-Alpes, France. It provides advanced treatment for a population of 2,750 and has a designed capacity of 2,500 m³/day.
The CHALAMONT wastewater treatment plant is located in the commune of Chalamont, within the Ain department of the Auvergne-Rhône-Alpes region in eastern France. The facility serves a population of approximately 2,750 residents, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,500 m³/day and a current discharge volume of 490.60 m³/day, the plant operates well within its capacity, ensuring effective treatment of incoming wastewater. The treated effluent is discharged into local watercourses that ultimately drain into the Rhône River basin. The Rhône is one of Europe's major rivers, flowing into the Mediterranean Sea. The advanced treatment level helps protect downstream aquatic ecosystems and supports the ecological health of the Rhône watershed.
Environmental context
The plant discharges into local streams that are part of the Rhône River basin. The Rhône flows southward through southeastern France and into the Mediterranean Sea via the Camargue delta. This watershed supports diverse aquatic life and is an important ecological corridor. Advanced treatment at this plant helps reduce nutrient and pollutant loads, contributing to the protection of downstream water quality and the sensitive coastal environments of the Mediterranean.
