Overview
ONDRES wastewater treatment plant serves Ondres in Nouvelle-Aquitaine, France, with a designed capacity of 1.00 and a population equivalent of 6,730. It operates under the EU Urban Waste Water Treatment Directive.
The ONDRES wastewater treatment plant is located in Ondres, a commune in the Landes department of Nouvelle-Aquitaine, southwestern France. The facility serves a population of approximately 6,730 and has a designed capacity of 1.00, reflecting its role in managing municipal wastewater for this coastal community. As a French wastewater treatment plant serving a small agglomeration (under 10,000 population equivalent), ONDRES is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires appropriate treatment for discharges into sensitive areas, with secondary treatment being the minimum standard for inland and coastal waters. The regulatory framework ensures compliance with national and European standards. The plant's treated effluent is discharged into the local environment, ultimately reaching the Atlantic Ocean via the Adour River basin. The region's coastal and estuarine ecosystems are ecologically sensitive, supporting diverse aquatic life and migratory species. Proper wastewater treatment is essential to protect water quality in the Bay of Biscay and maintain the ecological health of nearby wetlands and beaches.
Environmental context
The ONDRES plant discharges into the Adour River basin, which flows into the Bay of Biscay in the Atlantic Ocean. This coastal region supports important habitats for fish, birds, and marine life, including migratory species. The proximity to the coast (within 50 km) means that treated effluent must meet stringent quality standards to prevent nutrient enrichment and protect bathing waters and shellfish areas.
