Overview
CAZERES wastewater treatment plant serves Cazères, Occitanie, France. It treats wastewater for approximately 6,400 residents under EU Urban Waste Water Treatment Directive standards.
The CAZERES wastewater treatment plant is located in Cazères, a commune in the Haute-Garonne department of Occitanie, southern France. The facility serves a population of approximately 6,400 people, placing it in the small-to-medium agglomeration category under European Union classification. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent are required to provide secondary treatment. The plant operates within this regulatory framework, ensuring compliance with French and European water quality standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Garonne River. The Garonne flows through southwestern France and into the Gironde estuary, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.
Environmental context
The CAZERES plant discharges into the Garonne River basin, which flows through the Occitanie region and eventually reaches the Gironde estuary on the Atlantic coast. The Garonne supports a variety of fish species, including migratory fish like salmon and eels, and its waters are used for irrigation and drinking water supply. The plant's treatment helps protect this ecologically important river system from nutrient pollution and pathogens.
