Overview
AINHOA DANCHARIA 2012 is an advanced wastewater treatment plant in Saint-Pée-sur-Nivelle, Nouvelle-Aquitaine, France, serving 1,696 people with a designed capacity of 2,500 m³/day.
AINHOA DANCHARIA 2012 is an advanced wastewater treatment plant located in Saint-Pée-sur-Nivelle, within the Pyrénées-Atlantiques department of Nouvelle-Aquitaine, France. The plant serves a population of 1,696 and has a designed capacity of 2,500 m³/day, with a current discharge volume of 302.56 m³/day. It is situated near the coast, less than 10 km from the Atlantic Ocean. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), advanced treatment is required for discharges into sensitive areas, such as coastal zones. For a small agglomeration of this size, the directive mandates secondary treatment as a minimum, but the plant's advanced level indicates a higher standard of environmental protection. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Nivelle River and the Bay of Biscay. The coastal environment supports diverse marine life and is an important area for migratory fish species. The plant's advanced treatment helps protect these ecosystems from nutrient pollution and other contaminants.
Environmental context
The plant discharges into the Nivelle River basin, which flows into the Bay of Biscay on the Atlantic coast. This coastal region supports diverse marine habitats, including estuaries and wetlands that serve as nurseries for fish and stopover sites for migratory birds. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in the sensitive coastal waters.
Frequently asked questions
The plant is located in Saint-Pée-sur-Nivelle, in the Pyrénées-Atlantiques department of Nouvelle-Aquitaine, France, near the Atlantic coast.
The plant serves a population of 1,696 people.
The treated effluent is discharged into the Nivelle River basin, which flows into the Bay of Biscay on the Atlantic Ocean.
The plant provides advanced treatment, which includes nutrient removal beyond secondary treatment, as required for sensitive coastal areas under the EU Urban Waste Water Treatment Directive.
As a French plant serving fewer than 2,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's advanced treatment exceeds this requirement, reflecting the sensitivity of the coastal receiving environment.
