Overview
Vallecrosia wastewater treatment plant serves Ventimiglia, Liguria, Italy, with a designed capacity of 1.00 and a population equivalent of 35,000. It operates under the EU Urban Waste Water Treatment Directive.
The Vallecrosia wastewater treatment plant is located in Ventimiglia, within the Liguria region of northwestern Italy. It serves a population equivalent of approximately 35,000 people, placing it in the medium agglomeration category under EU classification. The plant is situated near the coast, reflecting the region's Mediterranean coastal geography. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment for agglomerations of this size, with potential tertiary treatment if the receiving waters are designated as sensitive areas. The designed capacity is noted as 1.00, though the unit is unspecified; typical capacities for such plants range in the thousands of cubic meters per day. The plant's treated effluent likely discharges into the Ligurian Sea, part of the Mediterranean Sea, via local watercourses or directly. The Ligurian coast supports diverse marine ecosystems, including seagrass meadows and rocky reef habitats. Proper treatment is essential to protect coastal water quality and the region's tourism and fishing industries.
Environmental context
The Vallecrosia plant discharges into the Ligurian Sea, a basin of the Mediterranean Sea. The coastal waters of Liguria support ecologically sensitive habitats, including Posidonia oceanica seagrass meadows, which are crucial for biodiversity and carbon sequestration. The region's steep terrain and urbanized coastline make effective wastewater treatment vital to prevent nutrient enrichment and protect marine life.
