Overview
ST AFFRIQUE wastewater treatment plant serves Saint-Affrique in Occitanie, France. It treats wastewater for approximately 7,168 people under the EU Urban Waste Water Treatment Directive.
ST AFFRIQUE is a wastewater treatment plant located in Saint-Affrique, a commune in the Aveyron department of Occitanie, southern France. The plant serves a population of approximately 7,168 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a French facility, ST AFFRIQUE operates within the framework of the EU UWWTD, which requires secondary treatment for agglomerations of this size discharging into freshwater. The plant's treatment processes are designed to meet national standards set by the French Ministry of Ecology, with oversight from local water agencies. The treated effluent is discharged into the local watershed, which ultimately drains into the Tarn River system and then to the Garonne River, reaching the Atlantic Ocean via the Gironde estuary. The plant plays a key role in protecting the water quality of the Aveyron region's rivers and supporting downstream aquatic ecosystems.
Environmental context
ST AFFRIQUE discharges into the Sorgues River, a tributary of the Tarn, which flows into the Garonne and eventually the Atlantic Ocean. The plant helps protect the sensitive karstic landscape of the Grands Causses region, which supports diverse aquatic life and is an important area for migratory fish species. Its operation is critical for maintaining water quality in the Tarn basin.
