Overview
GHISONACCIA wastewater treatment plant serves the commune of Ghisonaccia in Haute-Corse, Corsica, France. It is located near the coast and handles a population equivalent of 14,236.
The GHISONACCIA wastewater treatment plant is situated in Ghisonaccia, a commune in the Haute-Corse department of Corsica, France. The plant serves a population of approximately 14,236 people, placing it in the medium agglomeration category under French regulations. Its location near the Mediterranean coast makes its discharge management critical for coastal water quality. As a French wastewater facility, the plant operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (between 10,000 and 15,000 population equivalent), the directive requires secondary treatment as a minimum, with more stringent treatment if the discharge enters a sensitive area. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a moderate-scale facility. The plant's treated effluent ultimately reaches the Mediterranean Sea, likely via a small coastal stream or direct marine outfall. Corsica's coastal waters are ecologically sensitive, supporting diverse marine life including seagrass meadows and important fish nursery habitats. The plant's performance is therefore important for maintaining the region's environmental quality and tourism appeal.
Environmental context
The plant discharges into the Mediterranean Sea, a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution. The surrounding watershed includes small coastal streams that drain the Corsican mountains. The coastal zone supports seagrass beds and rocky reef habitats that are important for biodiversity. Effective wastewater treatment is essential to prevent eutrophication and protect marine ecosystems.
Frequently asked questions
The GHISONACCIA wastewater treatment plant is located in Ghisonaccia, a commune in the Haute-Corse department of Corsica, France. Its address is Route de la Mer, Ghisonaccia.
The plant serves a population equivalent of 14,236 people, classifying it as a medium-sized agglomeration under French and EU regulations.
The plant discharges treated effluent into the Mediterranean Sea, likely via a coastal outfall or a small stream. Its proximity to the coast indicates a marine discharge.
As a French wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. French regulations also mandate compliance with national water quality standards.
For agglomerations between 10,000 and 15,000 population equivalent, the EU UWWTD requires secondary treatment (biological treatment). In sensitive areas, such as coastal zones, tertiary treatment may be required to reduce nutrients like nitrogen and phosphorus.
