Overview
The CALVI wastewater treatment plant serves the city of Calvi in Haute-Corse, Corsica, France. It treats wastewater for a population of approximately 29,564 under the EU Urban Waste Water Treatment Directive.
The CALVI wastewater treatment plant is located in Calvi, a coastal town on the northwest coast of Corsica, France. The facility serves a population of about 29,564, classifying it as a medium agglomeration under EU regulations. The plant is situated near the historic citadel and the Mediterranean coastline. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The directive also mandates more advanced treatment if the receiving area is designated as sensitive. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale. The treated effluent is discharged into the Mediterranean Sea, which is a sensitive marine environment supporting diverse aquatic life and tourism. The plant plays a key role in protecting the coastal waters of the Gulf of Calvi, which are important for local fisheries, recreation, and the region's ecological balance.
