Overview
CREISSELS MILLAU wastewater treatment plant serves Creissels and Millau in Occitanie, France. It treats wastewater for approximately 39,467 people under EU Urban Waste Water Treatment Directive standards.
The CREISSELS MILLAU wastewater treatment plant is located in Creissels, near Millau in the Occitanie region of southern France. It serves a population of approximately 39,467 people, classifying it as a medium-sized agglomeration under EU regulations. As a French plant serving this population tier, it is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive mandates that agglomerations of this size must have appropriate treatment to protect receiving water bodies. The plant's operational context aligns with national French regulations that implement these EU standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Tarn River, a major tributary of the Garonne River. The Garonne flows into the Atlantic Ocean via the Gironde estuary. The Tarn River supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
The plant's treated effluent enters the Tarn River watershed, which flows through the scenic Gorges du Tarn before joining the Garonne River. The Garonne then reaches the Atlantic Ocean through the Gironde estuary. This river system supports diverse fish populations, including migratory species, and is ecologically sensitive to nutrient loading. Proper treatment helps maintain water quality in this important regional drainage basin.
