LERONE Wastewater Treatment Plant, Cogoleto, Liguria, Italy

The LERONE wastewater treatment plant is located in Cogoleto, within the province of Genova in the Liguria region of Italy. It serves a population of approximately 3,000 people, classifying it as a small agglomeration under Italian and EU regulations. The plant is situated near the coast, within 10 km of the Ligurian Sea. The plant operates with primary treatment only. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are generally required to provide secondary treatment or equivalent. However, discharges into coastal waters may be subject to less stringent requirements if studies show no adverse environmental impact. The designed capacity of 17,000 m³/day suggests the plant has potential for future expansion or serves additional industrial flows. The treated effluent is discharged into the Ligurian Sea, a part of the Mediterranean Sea. The coastal waters in this region support diverse marine life and are important for tourism and fisheries. The plant's proximity to the coast underscores the need for effective treatment to protect bathing waters and marine ecosystems.

LERONE discharges into the Ligurian Sea, a basin of the Mediterranean Sea. The coastal area near Cogoleto is ecologically sensitive, supporting seagrass meadows and diverse marine species. The plant's primary treatment level may pose risks to local water quality, particularly during tourist seasons when coastal pressures increase.
