Overview
Valence d'Agen Communale is a municipal wastewater treatment plant serving approximately 8,300 people in Valence, Occitanie, France. It operates under the EU Urban Waste Water Treatment Directive.
Valence d'Agen Communale is a wastewater treatment plant located in Valence, a commune in the Tarn-et-Garonne department of Occitanie, southern France. The plant serves a population of approximately 8,300 residents, classifying it as a small to medium agglomeration under EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment (biological treatment) for their wastewater. The regulatory framework ensures compliance with European standards for effluent quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River via the Tarn and Garonne rivers. The Garonne flows into the Gironde estuary and then the Atlantic Ocean. The plant plays a key role in protecting the water quality of these downstream water bodies, which support diverse aquatic life and are important for regional agriculture and recreation.
Environmental context
The plant discharges into the local watershed that feeds the Tarn River, a major tributary of the Garonne River. The Garonne flows into the Gironde estuary, a large estuary on the Atlantic coast of France. This watershed supports diverse aquatic ecosystems and is important for migratory fish species such as salmon and eels. The plant's treatment helps maintain water quality in this ecologically sensitive region.
