Overview
Ventimiglia Lungomare Varaldo wastewater treatment plant serves approximately 42,550 people in Italy. Located within 50 km of the coast, it discharges into the Ligurian Sea.
The Ventimiglia Lungomare Varaldo wastewater treatment plant is a municipal facility serving the coastal city of Ventimiglia in Liguria, Italy. With a population equivalent of 42,550, it falls under the EU classification of a medium agglomeration, requiring secondary treatment under the Urban Waste Water Treatment Directive (91/271/EEC). As an Italian plant, it operates under national regulations implementing the EU UWWTD, which mandates secondary biological treatment for agglomerations above 2,000 population equivalent. The plant's proximity to the coast (within 50 km) suggests it may discharge into sensitive coastal waters, potentially requiring more advanced treatment to protect marine ecosystems. The treated effluent is discharged into the Ligurian Sea, part of the Mediterranean Sea. This coastal area supports diverse marine life, including seagrass meadows and fish nurseries. The plant plays a critical role in preventing untreated sewage from reaching bathing waters and marine habitats, contributing to regional water quality and tourism.
Environmental context
The plant discharges into the Ligurian Sea, a basin of the Mediterranean Sea. This coastal zone is ecologically sensitive, supporting seagrass meadows (Posidonia oceanica) and diverse marine fauna. The area is also important for tourism and fisheries, making nutrient and pathogen removal essential to prevent eutrophication and safeguard public health.
Frequently asked questions
The plant is located in Ventimiglia, a coastal town in the Liguria region of northwestern Italy, near the border with France.
The plant serves a population equivalent of approximately 42,550 people, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent is discharged into the Ligurian Sea, part of the Mediterranean Sea, likely via an outfall pipe. The plant's coastal location requires compliance with stringent discharge standards to protect marine water quality.
As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 PE. For coastal discharges, additional treatment may be required to meet sensitive area criteria.
For medium agglomerations in Italy, secondary biological treatment (e.g., activated sludge) is standard. Plants near sensitive coastal areas often incorporate nutrient removal (nitrogen and phosphorus) to prevent eutrophication.
