POZZAVEGLI Wastewater Treatment Plant, Lenola, Lazio, Italy

POZZAVEGLI is a wastewater treatment plant located in Lenola, in the Lazio region of Italy. It serves a population of approximately 3,000 people and is situated near the Tyrrhenian Sea coast. The plant is part of Italy's municipal wastewater infrastructure, which operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU directive for agglomerations of this size. Its designed capacity is 3,000 m³/day, and it discharges 593.89 m³/day of treated wastewater. The advanced treatment level indicates that the plant likely includes nutrient removal or other tertiary processes to protect sensitive coastal waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The coastal location means the plant plays a crucial role in preventing nutrient pollution and protecting marine ecosystems. The Lazio region's coastal waters support diverse aquatic life and are important for tourism and fisheries.

The plant discharges into the local watershed that flows to the Tyrrhenian Sea, a semi-enclosed sea within the Mediterranean. The coastal area is ecologically sensitive, supporting seagrass meadows and marine biodiversity. Advanced treatment helps reduce nutrient loads, mitigating eutrophication risks in the coastal zone.
