Overview
CAUSSADE wastewater treatment plant serves Caussade, Occitanie, France, with a population equivalent of 16,132. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The CAUSSADE wastewater treatment plant is located in Caussade, a commune in the Tarn-et-Garonne department of Occitanie, southern France. The facility serves a population equivalent of approximately 16,132, classifying it as a medium-sized agglomeration under European Union regulations. As a plant of this scale in France, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River via the Tarn River system. The Garonne flows into the Gironde estuary and then the Atlantic Ocean. This waterway supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
The CAUSSADE plant discharges into the Tarn River basin, a tributary of the Garonne River. The Garonne flows through southwestern France into the Gironde estuary, a major Atlantic coastal ecosystem. The watershed supports diverse aquatic species and is a critical migratory route for fish such as Atlantic salmon and European eel. The region's agricultural and industrial activities place demands on water quality, making effective wastewater treatment essential for protecting downstream habitats.
