GRENADE 2 Wastewater Treatment Plant, Grenade, Occitanie, France

GRENADE 2 is a wastewater treatment plant located in Grenade, a commune in the Haute-Garonne department of Occitanie, southern France. The facility serves a population of about 6,823, classifying it as a small to medium agglomeration under EU regulations. It is situated near the Chemin du Pont du Diable, close to the Garonne River. As a French plant serving fewer than 10,000 people, GRENADE 2 is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. For agglomerations of this size, secondary treatment is typically mandated unless the receiving waters are designated as sensitive areas, which may require more advanced treatment. It operates within France's national regulatory framework enforced by the local water agency. The treated effluent from GRENADE 2 is discharged into the local watershed, ultimately flowing into the Garonne River. The Garonne is a major river in southwestern France, draining into the Gironde estuary and then the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Garonne, which supports diverse aquatic life and is used for agriculture, recreation, and drinking water downstream.

GRENADE 2 discharges into the Garonne River basin, which flows through Occitanie and Nouvelle-Aquitaine before reaching the Gironde estuary and the Atlantic Ocean. The Garonne supports a variety of fish species, including migratory fish like salmon and eels, and its floodplain provides important habitats. The plant's treatment helps maintain water quality in this ecologically significant river system.
