CAPDENAC Agglo Wastewater Treatment Plant, Capdenac-Gare, Occitanie

CAPDENAC Agglo is a wastewater treatment plant located in Capdenac-Gare, within the Occitanie region of southern France. The facility serves a population of around 31,087, classifying it as a medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in the Aveyron department, near the Lot River valley, and plays a key role in managing municipal wastewater for the local community. As a French plant of this scale, CAPDENAC Agglo is required to meet secondary treatment standards under the EU UWWTD, which applies to agglomerations with a population equivalent (PE) above 2,000. The plant's design and operation align with national regulations transposed from the directive, ensuring compliance with European water quality standards. The treated effluent from CAPDENAC Agglo is discharged into the local watershed, which ultimately drains into the Lot River, a tributary of the Garonne River. The Garonne flows into the Gironde estuary and then the Atlantic Ocean. The plant's operations help protect the Lot River's water quality, supporting aquatic life and downstream ecosystems in the Garonne basin.

The CAPDENAC Agglo plant discharges into the Lot River watershed, which flows into the Garonne River and eventually the Gironde estuary and Atlantic Ocean. The Lot River supports diverse aquatic habitats and is important for regional biodiversity. The plant's treatment processes help maintain water quality in this river system, which is used for recreation and supports fish populations such as pike and perch.
