GAP VILLE Wastewater Treatment Plant, Gap, Provence-Alpes-Côte d'Azur

GAP VILLE is a municipal wastewater treatment plant located in Gap, Hautes-Alpes, within the Provence-Alpes-Côte d'Azur region of southeastern France. The plant serves a population of around 67,450, classifying it as a medium-to-large agglomeration under EU regulations. As a French facility, GAP VILLE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For discharges into sensitive areas, tertiary treatment may be mandated. Compliance with national and EU standards is expected. The plant discharges treated effluent into the local watershed, likely the Luye River or a tributary, which flows into the Durance River. The Durance is a major river in the region, eventually joining the Rhône near Avignon. The Rhône then flows into the Mediterranean Sea. The plant plays a key role in protecting the Durance and Rhône river ecosystems from nutrient pollution.

The treated effluent from GAP VILLE enters the Luye River, a tributary of the Durance River. The Durance flows into the Rhône, which discharges into the Mediterranean Sea. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The plant's operations help maintain water quality in these downstream environments.
