Overview
VIA S PAOLO is an advanced wastewater treatment plant in Isola del Liri, Lazio, Italy. It serves 3,300 people with a designed capacity of 3,500 m³/day and discharges 653.28 m³/day of treated effluent.
VIA S PAOLO is an advanced wastewater treatment plant located in Isola del Liri, a town in the province of Frosinone, Lazio, Italy. The facility serves a population of approximately 3,300 residents, reflecting its role in managing municipal wastewater for this small community. The plant's designed capacity is 3,500 cubic meters per day, with an average discharge volume of 653.28 cubic meters per day, indicating operational headroom for future growth. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) and enhanced pathogen reduction, ensuring high-quality effluent. As an Italian facility, it operates under national regulations that transpose EU directives, with oversight from regional environmental authorities in Lazio. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tyrrhenian Sea via the Liri River and its tributaries. The Liri River basin supports diverse aquatic ecosystems and is part of a region known for its karst springs and waterfalls. The advanced treatment helps protect downstream water quality, particularly in sensitive areas where nutrient loading could impact coastal marine environments.
Environmental context
The plant discharges into the Liri River basin, which flows through central Italy before reaching the Tyrrhenian Sea near Gaeta. The Liri River is part of a karstic landscape with significant groundwater interactions, supporting diverse freshwater species. Downstream, the river passes through agricultural areas and eventually enters the Tyrrhenian Sea, a semi-enclosed basin with sensitive marine ecosystems. Advanced treatment at this plant helps reduce nutrient and pollutant loads, mitigating eutrophication risks in coastal waters.
