Overview
SAINT CHAMOND wastewater treatment plant serves L'Horme, France, with a population equivalent of 71,221. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The SAINT CHAMOND wastewater treatment plant is located in L'Horme, within the Auvergne-Rhône-Alpes region of France. It serves a population equivalent of 71,221, placing it in the medium-to-large agglomeration category under EU classification. The plant is situated near Saint-Étienne and is part of the Loire department's wastewater infrastructure. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. For larger agglomerations discharging into sensitive areas, tertiary treatment may be mandated. Regulatory compliance ensures a minimum of secondary treatment. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Loire River. The Loire is one of France's major rivers, flowing over 1,000 kilometers to the Atlantic Ocean. The river supports diverse aquatic life and is an important ecological corridor. The plant's operations contribute to protecting water quality in this significant river basin.
Environmental context
The SAINT CHAMOND plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is a vital freshwater resource, supporting diverse fish species and migratory birds. The watershed includes sensitive areas that may require advanced treatment to prevent eutrophication. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its discharge affects downstream water quality in the Loire estuary.
